 Aerotech’s ANT-20G goniometers represent a significant
breakthrough in the high-accuracy angular alignment of
components. This unique design utilizes Aerotech’s best-inclass
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
assure 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.
