Overview of Light-Curing Systems
SPOT-LAMP SYSTEMS
Dymax spot-lamp systems provide high intensity (up to 17,000
mW/cm2 (320-395 nm)) curing over a small area (typically <½",
5 mm diameter). These intensities usually result in a
0.5-5 second cure time. Available in both UV, visible, and LED
light-curing models, Dymax spot-curing systems utilize an
integral timed/manual shutter and typically require little
external shielding. An intensity adjustment feature aids users
in both validating and controlling a light-curing process.
Spot-lamp systems are ideal for curing small areas quickly and
can be easily integrated into an automated assembly process
or used as a turnkey bench-top systems. Learn more about
Dymax spot-curing lamps on pages 7-10.

SPOT/FLOOD-LAMP SYSTEMS
Dymax offers flexible LED light-curing systems which can be
easily configured as a spot lamp or a flood lamp. These units
provides all the benefits of Dymax’s advanced LED light-curing
technology in a flexible system design that can adapt to meet
changing business and application needs. Learn more about
Dymax spot/flood curing systems on pages 11-12.
BlueWave® LED DX-1000 Spot/Flood Lamp System
LIGHT-CURING FLOOD-LAMP SYSTEMS
Dymax light-curing flood-lamp systems offer moderate to high
intensity (75-225 mW/cm2) over a larger area (typically 5" x 5"
or 8" x 8" (127 mm x 127 mm or 203 mm x 203 mm)). UV,
visible, and LED light-curing models are available. These lamps
are ideal for curing areas larger than ½" (12.7 mm) in diameter
or curing many small parts simultaneously.
Dymax light-curing flood-lamp systems can be incorporated
into conveyors, automated assembly systems, or used as
turnkey bench-top units. Learn more about Dymax light-curing
flood-lamp systems on pages 15-17 of this guide.

Overview of Light-Curing Systems
CONVEYORS
Dymax conveyors incorporate either flood or focused-beam
curing systems. The benefits of light-curing conveyors include
consistent cure times and the ability to cure larger parts.
Conveyors also completely shield operators from UV light.
Dymax conveyors have 12" wide belts, and can be configured
for 6" and 12" width curing with UV flood lamps or 5" and 10"
with LED flood arrays. Conveyor speed is tightly controlled and
typically ranges from 1-32 feet per minute. Dymax light-curing
conveyors can be outfitted with different types of lamps and
up to four lamps on a single conveyor. Learn more about
Dymax light-curing conveyors on pages 20-24.
RADIOMETERS
A radiometer is a device that measures the intensity and/or
dose associated with light of specified wavelengths. UV light is,
by definition, not visible and so a radiometer is required to
determine UV intensity. Dymax’s ACCU-CAL™ radiometers are
ideal for measuring the intensity of spot lamps, flood lamps,
and conveyors. These radiometers measures intensity and
dose in the UVA (320-395 nm) range. The ability to measure
light intensity is useful for three reasons: maintaining a
controlled light-curing process, providing a “worker friendly”
light-curing process, and measuring light-transmission rates
through substrates. Learn more about Dymax radiometers on
pages 25-26 of this guide.

This guide contains the most popular Dymax light-curing
systems and radiometers. Additional turnkey equipment and
accessories are available including additional conveyors
(wider, shorter, faster, or higher clearance), dispensing
systems (time/pressure syringe dispensers, and valve/
pressure pot systems), dispensing needles, and more. In some
cases, Dymax will custom design a light-curing system to fit
your specific needs. Contact Dymax directly for more

Fundamentals of Light Curing
Developing a successful light-curing process requires
knowledge of the following key concepts.
Higher Intensity = Faster Cures – Intensity is the light energy
reaching a surface per time and it is often measured in
mW/cm2. Higher intensity light (of the proper wavelengths)
will generally provide faster cure.
Shortwave and Longwave Bulbs – Dymax UV light-curing
systems can be outfitted with either shortwave bulbs
(emphasizing UVB and UVC) or longwave bulbs (emphasizing
UVA and visible light). Longwave bulbs are recommended for
curing most Dymax (and similar) light-curing materials due to
their superior depth of cure and substantial visible-light
intensity. The chart at the bottom of this page describes the
portion of the electromagnetic spectrum emitted by standard
Dymax longwave bulbs.
Distance and Substrates Affect Intensity – Distance from a
light-curing lamp always affects intensity. Intensity decreases
with increasing distance from both spot lamps and floodcuring systems, especially spot lamps. Intensity decreases with
increasing distance from the focal point for focused-beam
systems. Intensity is also reduced when curing through
substrates that transmit less than 100% of the light used for
curing. Advances in light-curable adhesive technology now
allow curing through most translucent substrates, even those
that block UV completely.
that curing is complete when further light exposure no longer
improves product properties. Quantitative testing of cured
specimens can be used to determine the minimum exposure
time and/or minimum intensity required for complete cure.
The graph on page 28 shows how this method could be used
in a bonding application.
Shadows – Light-curable materials will not cure unless
exposed to light of appropriate wavelength, intensity, and
duration. For applications where shadowed areas may be an
issue, Dymax offers a line of light-curable materials that are
formulated to also cure over time with heat or moisture.
Oxygen Inhibition – In some cases, light-curable adhesive
surfaces exposed to oxygen during curing may remain tacky
after cure. This is caused by oxygen inhibition. Oxygen in the
air actually slows the cure at the top-most layer of an airexposed coating surface. This tackiness does not necessarily
indicate incomplete cure and can be observed with some
materials, even after complete cure. In general, there are four
ways to minimize or eliminate the tackiness associated with
oxygen inhibition:
■
Longer and/or Higher Intensity Cure – In many cases, curing
longer or with higher intensity will minimize or eliminate a tacky
surface.
■
Use of “Shortwave” Bulb – Use of a UVB (shortwave) bulb instead
of a UVA (longwave) bulb may also help to eliminate surface
tack. A UVB bulb may, however, result in a limited depth of cure.
Limited Depth of Cure – Since light-curable materials themselves absorb light, each has a maximum depth of cure. For
most Dymax products, this depth is between ¼" (6.35 mm) and
½" (12.7 mm).
■
Choose an Alternate Dymax Material – An alternate formulation
may cure “tack free” more readily.
■
Blanket with Inert Gas – Blanketing exposed resin surfaces with
inert gas (like nitrogen or argon) during cure can often eliminate
the problem of oxygen inhibition completely.
Determining Complete Cure – Changing from a liquid to a solid
is a simple definition of cure. A more complete definition is

Designing a Light-Curing Process
There are several factors to consider when designing a lightcuring process.
beneath three separate lamps. Brief interruptions during cure
are acceptable.
Intensity – A well-designed light-curing process incorporates a
curing system with excess intensity. Excess intensity provides
both a safety margin and long bulb life. See page 28 “Setting
Up and Monitoring a Light-Curing Process” for specific
intensity and safety margin guidelines.
Safety – Proper equipment set-up and operator training are
the keys to developing a safe light-curing process. Always
follow the operation manual to ensure safe installation. Proper
shielding, protective equipment, and eye protection are
required to ensure a safe light-curing process.
Spectral Output – It is important to match the spectral output
of the lamp to the material and application. Dymax supplies
both shortwave bulbs (also called Mercury or “H”) and
longwave bulbs (also called Metal Halide or “D” bulbs). In
general, longwave bulbs emit primarily UVA providing superior
depth of cure, while shortwave bulbs emit primarily UVB/UVC
providing superior surface cure for coatings and inks.
Longwave bulbs are recommended for most applications
involving Dymax materials.
Controls – Unless exposed to light of sufficient wavelength,
intensity, and duration, most light-curing materials will remain
uncured. To insure a consistent exposure time, timed shutters
are standard on spot lamps and available for most flood and
focused-beam systems. A digital speed controller on Dymax
conveyors insures consistent exposure times.
Curing Area – The size of the area to be cured may dictate
which type of lamp is appropriate. Spot lamps are typically
used to cure areas less than ½" (12 mm) in diameter. Flood or
focused-beam lamps are used when curing large areas (up to
8" x 8" (203 mm x 203 mm)). Multiple flood lamps or
conveyors can be used to cure even larger areas.
Avoid Creating a “Bottleneck” – Ideally, the light-curing
process is designed to be faster than the limiting or
“bottleneck” step in the overall manufacturing process.
Dispensing, assembling, testing, or packaging parts while other
parts are curing will maximize efficiency.
Lamp intensity should be regularly monitored with a
radiometer. Bulb replacement and/or appropriate lamp
maintenance should be conducted when intensity dips below
a pre-determined minimum value.
Bulb Life – The cost of replacement parts can be an important
consideration when selecting a light-curing system. Generally,
low bulb-replacement costs are achieved by selecting a lamp
with intensity to spare, thereby extending allowable bulb life.
Price Per Bulb x Frequency = Bulb Replacement Cost
Curing Multiple Parts Simultaneously – In some cases, it is
more efficient to cure many small parts simultaneously using a
flood or conveyor than to cure each part individually. For
example, a spot lamp may cure one small part every three
seconds (or 20 parts-per-minute) whereas a flood lamp may
cure 20 small parts every 15 seconds (or 80 parts-per-minute).
Multiple Cure Stations – On an automated production line
where the required cure time exceeds the index/cycle time,
multiple cure stations can be used. For example, if a part
requires nine seconds to cure and the index/cycle time is only
three seconds, each part can be cured for three seconds

Lightguides for Spot Lamp Systems
LIGHTGUIDES
Lightguides transmit UV and visible light from a source
mounted inside of a spot-curing unit to the curing area. There
are several factors to consider when choosing a lightguide.
Length – Lightguides are commonly one meter long although
other lengths are available.
Curing Area/Intensity vs. Distance – The UV and visible light
emitted from a lightguide diverges. As a result, intensity
decreases and curing area increases with distance from the
end of the light guide. The chart below describes this
relationship clearly for the 5-mm liquid lightguide.
Diameter – Single-pole lightguides are available with 3-mm,
5-mm, or 8-mm inside diameters. Although the 5-mm
lightguide will register a higher intensity, the 8-mm lightguide
provides more curing power (intensity x area) because a larger
lightguide opening captures more of the light emitted from the
bulb. Each pole of a multi-pole lightguide has an inside
diameter of 3 mm.
Multiple Poles – Light emitting from a spot lamp can be
channeled through a single lightguide (single pole) or split
between multiple lightguides (multiple poles). Each pole of a
multi-pole lightguide emits equal intensity (typically  10% for
liquid-filled lightguides) and all share a common shutter. Both
liquid-filled and quartz-fiber multi-pole lightguides are
available from Dymax.
Connection – There are basically two types of connectors used
in the spot lamp industry, “Wolf” and “D” connectors. Dymax
provides lightguides with both connector types, although “D”
connectors are an industry standard and compatible with
current Dymax lamp designs (older Dymax designs utilized
“Wolf” connectors).

CURING WITH LIGHT EMITTING DIODES (LEDS)
The BlueWave® LED flood lamp generates curing energy using
high-intensity LEDs. LEDs offer many advantages over
conventional bulbs including constant intensity, no required
warm-up time, and a life span of over 20,000 hours. The
relatively narrow frequency band produced by LEDs also
generates cooler curing temperatures making this unit ideal
for use with thermally sensitive substrates.
17
BlueWave® LED Flood Lamp System Shown with VisiCure™
Array and Standard Mounting Stand
When compared to other LED units, the BlueWave® LED Flood
provides much higher intensity and more overall uniformity
across the active area. These benefits allow shorter cure times,
and in turn, faster manufacturing throughput.
The following graph illustrates the Dymax BlueWave® LED
Flood’s high uniformity when multiple arrays are positioned
next to each other. This is especially important in conveyor
applications to ensure a consistent cure across the entire
substrate.

MOUNTING STANDS
Standard Mounting Stand Kit – A simple and cost effective

Turning a bulb off and on between cycles is not practical since
each off/on cycle shortens bulb life and requires a 5-minute
warm-up period. A shutter, however, can be used to shield a
flood system between cycles. Shutters control exposure time,
reduce heat on the work surface, and shield operators from
exposure to UV light. There are two types of shutters pictured
below. Both ZIP™ and manual shutters are compatible with
Dymax flood lamps.

Radiometers for Light-Curing Systems
A radiometer is a device that measures the intensity and/or
energy associated with light of specified wavelengths. UV light
is, by definition, not visible and so a radiometer is required to
determine UV intensity. Dymax offers the ACCU-CAL™ 50 for
spots, floods, and conveyors. The ability to measure light
intensity is useful for three reasons:
1.
2.
3.
Maintaining a light-curing process – A radiometer can
measure whether a light-curing system is providing
intensity above the “bulb change” intensity. A radiometer
is to a light-curing process what a thermometer is to a
heat-curing process.
Providing a worker-friendly light-curing process – A
radiometer is required to determine if any UV light is
reaching operators or bystanders.
Measuring transmission rates through substrates – A
radiometer can be used to measure the transmission rates
of various wavelengths through substrates that absorb UV
and/or visible light. To assure an effective curing process
it is critical to measure the light intensity reaching the
light-curable material below the intervening substrate.
ACCU-CAL™ 50 RADIOMETER
Dymax’s ACCU-CAL 50 is capable of measuring both the UV
intensity (mW/cm2) and dose (J/cm2) emitted from spot
lamps*, flood lamps, and conveyors. This easy-to-use
radiometer is compatible with 3-mm, 5-mm and 8-mm
lightguides and only requires re-calibration once per year.
Please refer to Dymax literature #Lit159 for more information.

The ACCU-CAL 50V radiometer is simple to operate and offers
repeatable measurement of visible light. The ACCU-CAL 50V
can measure visible light energy emitted from lightguides
(3 mm, 5 mm, and 8 mm), flood systems, and conveyors. With
a spectral sensitivity from 395 to 465 nm (blue portion of the
visible spectrum), the ACCU-CAL 50V measures intensities
from 1 mW/cm2 to 40 W/cm2. A specially designed photo
sensor assembly protects the photo sensor from the high
temperatures sometimes associated with today’s highintensity spot lamps. Please refer to Dymax literature #Lit236
for more information.
Dymax’s ACCU-CAL 150 can measure UV light up to 10 W/cm2
emitted from stationary light-curing flood lamps or lamps used
in conveyorized processes. This radiometer can be used to
determine intensity (mW/cm2) or total energy as derived from
intensity and exposure time (mJ/cm2). Calibration is
recommended every six months to ensure proper operation of
the radiometer. Please refer to Dymax literature #Lit290 for
more information.

Light-Curing Safety
Dymax ultraviolet light-curing technology has been used
successfully for over 30 years. The fast cure, one-component
nature of our UV light-curing technology has made it the
process of choice for many manufacturers requiring a “Cure on
Demand” assembly process. There are three common
questions/concerns related to UV light-curing systems: UV
exposure, ozone, and bright visible light.
SHIELDING THE SOURCE OF UV
Any substrate that blocks UV light can be used as a shield to
protect workers from stray UV light. The following materials
can be used to create simple shielding structures or blind
corners:
■
Sheet Metal – Aluminum, steel, stainless steel, etc.
Sheet metal should be coated black or black anodized to
minimize reflection of UV and visible light.
■
Rigid Plastic Film – Transparent, UV-blocking plastics
(typically polycarbonate or acrylic) are commonly used
to create shielding where transparency is also desired.
These rigid plastic films are available either water-clear
or tinted, (to reduce visible light glare).
■
Flexible Film – UV-blocking, flexible urethane films can
be used to quickly create workstation shielding. This UVblocking, flexible urethane film is available from Dymax.
UV EXPOSURE
Standard Dymax UV light-curing systems and bulbs have been
designed to primarily emit UVA light1. UVA light is generally
considered the safest of the three UV ranges: UVA, UVB, and
UVC. Although OSHA does not currently regulate ultraviolet
light exposure in the workplace, the American Conference of
Governmental Industrial Hygienists (ACGIH) does recommend
Threshold Limit Values (TLVs) for ultraviolet light. The
strictest interpretation of the TLV (over the UVA range) for
workers’ eyes and skin is 1 mW/cm2 (intensity), continuous
exposure. Unless workers are placing bare hands into the
curing area, it is unusual to exceed these limits. To put
1 mW/cm2 limit into perspective, cloudless summer days in
Connecticut regularly exceed 3 mW/cm2 of UVA light and also
include the more dangerous UVB light (primarily responsible
for sun burns) as well.
The human eye cannot detect “pure” UV light, only visible
light. A radiometer should be used to measure stray UV light
to confirm the safety of a UV light-curing process. A
workstation that exposes an operator to more than 1 mW/cm2
of UVA continuously should be redesigned. UV adhesive light
curing can be a regulatory-compliant, “worker-friendly”
manufacturing process when the proper safety equipment and
operator training is utilized. There are two ways to protect
operators from UV exposure: Shield the operator and/or
shield the source.
SHIELDING THE OPERATOR
■
UV-Blocking Eye Protection – UV-blocking eye protection
is recommended when operating UV light-curing systems.
Both clear and tinted UV-blocking eye protection is
available from Dymax.
■
UV-Blocking Skin Protection – Where the potential exists
for UV exposure upon skin, opaque, UV-blocking clothing,
gloves, and full face shields are recommended.
27
OZONE
Standard Dymax bulbs (UVA type) generate an insignificant
amount of UVC and therefore essentially no ozone1. Some UV
light-curing systems, like those used to cure UV inks, emit
primarily “shortwave” (UVB and UVC) energy. Upon exposure
to UVC light (specifically <240 nm), oxygen molecules (O 2) split
into oxygen atoms (O) and recombine with O2 to create Ozone
(O3). The current, long-term ozone concentration limit
recommended by ACGIH, NIOSH, and OSHA is 0.1 ppm
(0.2mg/m3).
BRIGHT, VISIBLE LIGHT
The bright, visible light emitted by some UV light-curing
systems may be objectionable to some workers and may cause
eyestrain. Tinted eye protection and/or opaque/tinted
shielding can be utilized to address this concern.
SUMMARY
UV light sources can be more “worker friendly” than many
commonly accepted industrial processes, provided the
potential concerns are addressed. Contact your Dymax
representative for information regarding the proper use of
Dymax UV light-curing systems.
1Dymax
also provides special order “shortwave” bulbs that emit primarily UVB and UVC
light. Contact Dymax directly for information regarding the use of “shortwave” bulbs.
Setting Up & Monitoring a Light-Curing Process
There are two parameters that must be considered to ensure
a successful light-curing process, 1) intensity at the curing
location and 2) cure time. Dymax recommends setting up and
monitoring a UV light-curing process as follows:
1.
Choose a Light-Curing Material (LCM) – Select an LCM
that satisfies the performance requirements of the
application.
2.
Determine available light-cure time – Determine the cure
time available so that the UV curing process is not a
“bottleneck” in the manufacturing process. For example,
if dispensing and assembly requires 12 seconds per part in
a one piece flow process, the maximum available cure
time is 12 seconds. For a light-curing conveyor, determine
the minimum line speed required.
3.
Choose a light-curing system – Choose the appropriate
light-curing system that will fully cure the LCM within the
cure time available. Dymax Applications Engineering can
help you identify the best light-curing system for a specific
application.
4.
Determine the lowest acceptable intensity – The lowest
acceptable intensity is that which fully cures the LCM in
the available cure time (determined above). The lowest
acceptable intensity can be determined through
quantitative testing of parts cured at various intensities as
shown in the diagram to the right. In the case of a
focused-beam lamp on a conveyor, determine the lowest
acceptable dose‡, not intensity.
5.
Monitor and maintain intensity – Using a radiometer,
monitor the UV light intensity at the bond line. If the
intensity reaches the “bulb change” intensity, install a new
bulb or conduct appropriate maintenance (see page 29
“Maximizing Lamp Performance”). In the case of a
conveyor, dose (not intensity) should be monitored.
If the resulting cure process is causing heat damage, a
cooling fan or shorter cure time is recommended. If the
resulting bulb life is too short, a longer cure time or higher
intensity lamp is recommended.
‡Both
residence time and intensity varies with lamp height on conveyors with
focused-beam lamps. For this reason, it is better to monitor dose (J/cm2) on
these systems rather than intensity. The most practical way to artificially
lower the dose on these systems is to adjust the line speed.
The following techniques may be used to artificially
modify intensity to facilitate determining the lowest
acceptable intensity.
■
Increase distance – Since light emitting from lightcuring lamps diverges, the intensity decreases as the
distance from the lamp increases. This is especially
useful for flood lamps.
■
Adjust Intensity – Some UV light-curing systems (like
the BlueWave® 200 with intensity adjustment
feature) allow users to adjust intensity.
Note: As with any manufacturing process, it is advisable
to operate with a safety factor. Dymax recommends a
“bulb change” intensity that is 50-100% higher than the
“lowest acceptable intensity”.
28
Maximizing Light-Curing Lamp Performance
There are three ways to maximize lamp performance:
1.
Proper Set-Up – The first key to maximizing lamp
performance is proper set-up. Reference the operation
manual provided with each Dymax lamp for instructions
on proper set-up. After ignition, wait five (5) minutes
before use to allow the lamp to reach full intensity. Then,
use the following techniques to maximize intensity at the
curing location.
■
Spot-Cure Systems – Maximize curing intensity by
minimizing distance from the end of the lightguide to
the light-curable material, while still covering the
curing area. Positive airflow can prevent those vapors
commonly emitted during cure from condensing on
the end of a lightguide. Be aware that excessive
bending, clamping, or set-screw tightening can
damage lightguides. The minimum bend radii for
standard lightguide diameters are as follows:
■
■
■
2.
3-mm lightguides – 40-mm bend radius
5-mm lightguides – 60-mm bend radius
8-mm lightguides – 100-mm bend radius
■
Flood Lamps – Minimize distance from the bottom of
the flood housing to the light-curable material. Note
that distances 3" (76.2 mm) or more from the lamp
housing provide the most uniform intensity across the
curing area.
■
Focused-Beam Lamps – Place light-curable material
at the focal point of the focused-beam lamp for
maximum intensity. The focal distance for the
Fusion® F300S is 2.1" (53.34 mm) below the lamp
housing.
Optimizing Bulb Life – The intensity of light being emitted
from UV bulbs gradually decreases with usage (except in
the Fusion F300S). This degradation cannot be avoided,
but it can be minimized through proper operation.
The longest bulb life is obtained by simply using the lamp
continuously (not turning it off). The more often the lamp
is cycled on and off, the more quickly the bulb degrades.
The general rule of thumb is to leave the lamp on if it will
be used again within an hour.
29
Once ignited, do not turn the lamp off for at least five
minutes. Turning the lamp off before it has reached its
operating temperature can damage the bulb. In addition,
do not attempt to re-start a UV light-curing system until it
has been allowed to cool for five (5) minutes.
3.
Proper Maintenance – As with all production equipment,
routine maintenance will optimize performance. In the
case of a spot lamp, keep the end of the lightguide clean
and replace it if it no longer transmits enough light (a
lightguide simulator is available from Dymax to help
determine lightguide transmission).
See Lit#069
Lightguide Simulator for more information on lightguide
and bulb maintenance. In the case of a flood lamp, the
reflector and lamp base (sockets that the bulb fit into)
should be cleaned and/or replaced as necessary. Please
refer to the user guide for each light-curing system for
further guidance on proper maintenance.
