1. Cells | 1.1 Material and Technical Information
1.1.1 Material
Our cells are manufactured from various types of glass. The most important criterion for
the choice of a particular type of glass is the spectral range for which the cell is intended
as well as the conditions of use. Coloured logos are fused onto each Hellma cell, thus
indicating the spectral range over which the cell can be used.
In general we divide the glass materials that we use into two groups: Quartz and
Optical Glass.
Quartz consists exclusively of silicon dioxide (SiO2) and shows some remarkable
properties:
■ Quartz displays a high UV transmission, in highly purified synthetic Quartz down to
well below 200 nm.
■ The thermal expansion of Quartz is extremely low, its coefficient of thermal expansion
being 6 x 10 -7 K -1 between 20 °C and 300 °C.
■ Quartz is chemically very resistant and maintains its shape, even at high temperatures
up to approximately 1000 °C.
Common criteria for all types of Optical Glass are
■ that the cells made from it are used in the visible range of the spectrum,
■ that the glasses we use are characterised by relatively low values of refractive index
and dispersion,
■ that they display good resistance to chemicals.

1.1.3 Material Codes
Identification Logos for UV Cells
J is the identification logo which indicates that quartz of the
highest purity and homogeneity has been used for the window. Because it is produced from a silicon compound, it is
also called synthetic quartz. We use quartz from Heraeus
Quarzglas GmbH and SCHOTT Lithotec AG, which gives
transmission values of more than 80 % over a spectral
range of between 200 nm and 2500 nm for an empty cell.
Identification Logos for Cells
for the Visible Spectrum
J indicates that SCHOTT type UK 5 is used for cells referred to in the catalogue as manufactured from “Special
Optical Glass”. This crown glass is made from exceptionally
pure raw materials, which gives an improved transmission
in the near ultraviolet range. An empty cell will give a transmission of more than 80 % over a spectral range of between 320 nm and 2500 nm.
J is a trademark that distinguishes cells which are not
used in spectrophotometry. Here, a glass is used, which we
refer to in the catalogue as “Optical Glass”. We use B 270
Superwite from SCHOTT DESAG and “Borofloat 33” from
SCHOTT JENAer Glas GmbH, a colourless highly transparent crown glass in the form of drawn panes with fire-polished surfaces. The quality of the surfaces is so high that the
components can be fused using the Hellma process without further grinding and polishing. An empty cell made of
B 270 Superwite will give a transmission of more than 80 %
over a spectral range of between 360 nm and 2500 nm.

1.1.4 Transmission
Transmission values are established by means of measurements performed on empty
cells with windows of 1.25 mm thickness. Depending on the wavelength transmission
values will be 5 % to 8 % higher if measurements are carried out with filled cells (distilled
water). When comparing the transmission values of cells or of windows made by different
companies, you should make sure that the conditions under which measurements were
made are the same. It is important to know whether measurements were made with
empty or filled cells and how thick the windows were.

1.1.5 Spectral Measurements
As a result of the improvements in glass production and through the perfection of the
polishing process, all cells are produced with transmission values, which within the limits
of the measuring uncertainty, agree with the theoretical transmission.
On request all cells can be spectrally calibrated and assembled into sets of equal transmission values (measuring uncertainty ± 1 %). These cells are provided with a three digit
calibration code number containing coded data about the material and the transmission
at a wavelength typical for the cell material.
In the case of a repeat order please be aware that, through usage, your cells will probably
not have the same high transmission values as the new cells.

1. Cells | 1.4 Other Supplies and Accessories
1.4.1 Other Supplies
Besides the standard cells shown here we also make cells for special purposes according to our customers’ specifications. Of special interest are our cells made of CaF2 used,
for instance, in DUV applications.
The well known selection of cells from our parent company, Hellma GmbH & Co. KG,
79371 Müllheim, Germany, represents an additional range of cells available to our customers. On request we would be happy to send you information about these. Items available include standard and flow-through cells, fibre-optical probes, and calibration standards
for all kinds of applications.
1.4.2 Mirror Coating
For some purposes (e.g. fluorescence measurements) mirror coated cells are used.
Both the rear window to the incident light and the left adjacent window are mirror-coated
on the outside. The standard mirror coating consists of a layer of vacuum-evaporated
aluminium that has a degree of reflection of more than 80 % over the spectral range
between 190 nm and 2500 nm. This coating is covered with a protective layer which is
extremely hard and durable. Additionally, the mirror-coated windows are protected
against external scratches by a layer of black lacquer.
On request we can also
supply metal coatings with
different reflective properties and with the coated
surfaces in other positions.
Reflectance of an aluminium layer
1.4.3 Accessories
Replacement lids and stoppers made of PTFE are available for cells with an external
width of 12.5 mm.
1.4.4 Cleaning of Cells
Hellmanex® II is an alkaline liquid concentrate for the efficient cleaning of cells and other
optical parts made of quartz and glass. It automatically and completely removes even the
most stubborn contaminants such as fats, oils, waxes, dried blood, proteins, pigments,
silicon oil, and traces of many other organic and inorganic substances.

2. Slides
Slides made of quartz are chemically very durable and are well suited for UV applications. We also offer slides made of high-index optical glass, which can be used if the difference in refractive indexes is a problem. Slides made of optical glass supplied by
SCHOTT can be made upon request. Here is a selection of slides with standardised
dimensions.

3. Optical Components and Special Optics
Additionally we offer our customers diverse flat optics (substrates, spacers, retarders,
prisms, wedges, etc.), cylindrical lenses, torical lenses, parts with conical surfaces (cones)
and optical filters.
Generally speaking optical components can be made of any glass offered in SCHOTT’s
catalogues (“SCHOTT Optical Glass” and “SCHOTT Optical Glass Filters”). Additionally
the materials SCHOTT Borofloat, SCHOTT Duran, SCHOTT Zerodur and DESAG 270 as
well as quartz from SCHOTT Lithotec and from Heraeus or any equivalent materials from
other producers can be used.
Other materials: CaF2, sapphire, silicon, germanium, etc.
Using modern equipment and the advantages of new techniques we are able to offer
components with polished surfaces of such high quality that they are well-suited for laser
technologies. In order to avoid misunderstandings which can arise due to unclear or
incomplete specifications, one should be sure to pay attention to the following points.
The quality of polished surfaces is characterised by two mutually independent criteria:
first the surface must be free of any flaws such as scratches and holes as well as any
dull, unpolished spots. Secondly the evenness of the glass surface must be considered.
For demanding jobs such as occurs with interferometer mirrors, the requirements for
evenness should take into consideration what kinds of deformations are acceptable for
an even wave, which is reflected from or which passes through an “uneven” surface.
9
3. Optical Components and Special Optics
The designation of acceptable wavefront deformations in windows is especially important
because it accounts for the influence of both glass surfaces and by doing so the designation of evenness of both surfaces and their parallelism to one another becomes superfluous.
Various specifications
The thickness of a window in this case only has to conform to mechanical criteria
(pressure resistance, installation standards) – tolerances can be made correspondingly
larger. The designation of wavefront deformation should also be made for wedges in
analogous fashion.
If so desired, the flat optical parts can also be supplied with mirror coatings or AR coatings.
For AR coatings, please include the wavelength range and the required reflection percentage so that the optimal layer system can be determined. For mirror coatings, we offer a
standard aluminium layer which is protected by a layer of evaporated quartz in order to
improve durability.
Please send us your technical drawings including all important dimensions and the desired
quantity so that we can prepare an individualised price estimate.
If you are interested in these products simply request our product overview “Flat Optics /
Cylindrical Optics”.
