Nutfield Technology's QS-7 and 10
use low inertia, high stiffness
materials and an innovative
architecture to provide industry
leading performance. The QS-7 /10
has faster step response and higher
signal-to-noise position detection
compared to any scanner in its
class.
The QS-7/10 offers tremendous
torque in a small outline. This means
it can be packaged into a smaller
volume and still provide peak
performance. The Patent Pending
ceramic rotor design has
exceptionally low inertia and high
stiffness, which results in higher
bandwidth performance.
The QS-7/10 Position Detector was
designed with a high-output
feedback signal for the best possible
accuracy. NTI galvanometers have
three times greater signal-to-noise;
the highest in the industry. This
means greater pointing accuracy
and repeatability in your application.
High Torque/Inertia
♦ Patented SLR Stator
Design For Higher
Bandwidth
QuantumScan-7™
For 5-10 mm Beam Apertures
Another breakthrough is our stator
design, which is the first to
incorporate Patented Side Load
Reduction (SLR) technology to
reduce off axis magnetic forces on
the rotor. The benefit is higher
bandwidth and faster step response
resulting from less stator induced
side forces.
Nutfield Technology provides a
range of digital and analog control
options to meet your time to market
and budget requirements. Call us

customize a solution for your
application.

QuantumScan-30
Moving Magnet Galvanometers
Nutfield Technology's QS-30 uses
exotic materials and an innovative
architecture to provide industry
leading performance. The QS-30 has
faster step response, higher signalto-noise position detection and
improved thermal management
compared to any scanner in its class.
The Industry’s First
♦ Ceramic Rotor For
Faster Step Response
♦ Thermally De-Coupled
Stator For Lower Drift
♦ SLR Stator Design For
NTI continuously performs research
to improve scanner performance so
that your products remain
competitive in the marketplace. This
research has lead us to a patent
pending ceramic rotor design. This
first of a kind rotor has exceptionally
low inertia and high stiffness, which
results in higher bandwidth
performance.
Signal / Noise >100,000:1
The QS-30 Position Detector was
designed close to the mirror for the
best possible accuracy. Further
position detector refinements give
NTI galvanometers up to 8 times
greater signal-to-noise; the highest
in the industry. This means greater
pointing accuracy and repeatability
in your application.
NUTFIELD TECHNOLOGY, INC.
The galvanometer’s stator is
thermally isolated and located far
away from the position detector.
This reduces thermally induced
drift; a patent pending feature found
only in NTI galvanometers.

Nutfield Technology’s Flexure
Galvanometers have lower cross

scanners in the market. They
operate just like a galvanometer with
a constant spring force attached to
the rotor.

NTI flexure galvanometers use cross
flexure pivots instead of ball
bearings. Flexures are superior to
bearings in several ways including
long service life. Our flexures are
constructed from high quality
stainless steel spring material with
an endurance rating over 100 kPSI.
Our scanners run at low stress
levels, typically less than 10 kPSI.
They operate in the "infinite life"
portion of the stress curve. This
means that these units can run
continuously for many years.
Flexure pivots scan smoother
because there is no rolling friction or
surface finish issues between the
balls and raceways. The most
demanding raster imaging systems
use flexures because of their
excellent smoothness and
repeatability.
Flexure galvanometers have no
lubricants; so there is not an issue
with out gassing, which is important
in some vacuum applications.
Ball bearings are designed to rotate
through large enough angles to
sufficiently distribute lubrication
HarmonicScan-15™
For 7 - 15 mm Beam Apertures
within the bearing. Several problems
can arise when a ball bearing is
used in a galvanometer. Lubricant
can be displaced from the contact
area when the scan angle is small,
causing the balls and raceways to
wear.
Flexure based galvanometers are
not appropriate for all applications.
Call our experienced team for
assistance in selecting the
appropriate galvanometer for your
application.

* Flexure Scanners are best used in raster or small angle vector applications. Applications where the command
signal keeps the mirror positioned away from center by more than 7 degrees optical, for extended periods of
time, could cause over heating due to the spring force of the flexures.
