 Aerotech’s ANT-20G goniometers represent a significant
breakthrough in the high-accuracy angular alignment of
components. This unique design utilizes Aerotech’s best-in-class
direct-drive noncontact motor technology. When used
with Aerotech’s controllers, the ANT-20G series provides an
industry-leading positioning speed of 150 degrees per
second.
High-precision bearings, direct on-axis encoder feedback, and
noncontact and noncogging direct-drive technology ensure
the highest level of performance and make excellent
repeatability and in-position stability a reality. The goniometer
cradles can be mounted orthogonally to provide pitch and roll
about the same point in space. Combining this with a rotary
stage under the orthogonal assembly adds a third rotation
axis (pitch, roll, yaw) through the same point.
The critical elements of the ANT-20G goniometers, as with all
other ANT series nanopositioners, were selected to operate in
a 24/7 manufacturing environment. Unlike worm- or piezo-driven
goniometers, the ANT-20G series will not require
periodic adjustment or maintenance. This will assure many
years of trouble-free operation. The ANT-20G cradles are
available in four sizes.
