goniometers are used in applications where 90° of angular travel is needed
with the payload at the center of rotation, or where two axes of rotation are
needed about a common point. AGC goniometers can be mounted to standard optical
tables, as well as standard Aerotech rotary stages, to provide roll, pitch,
and yaw about a common 3-axis intersection. Performance includes ±12
arc sec accuracy, ±10 arc sec repeatability, 3.5 arc sec resolution,
a maximum speed of 78 degrees/second, and a maximum load of 50 kg. This flexible
stage series is ideal for optical alignment, payload tip/tilt, beam steering,
sensor calibration, laser applications, automated manufacturing and/or testing,
and multi-axis diffractometer systems.
Construction Features
Multiple AGC goniometers can be mounted on one another to form a rotary system
with all axes of rotation sharing a common intersection point. This allows compact
pitch/roll/yaw systems to be created easily from a standard stage platform and
without special adapter plates or mating fixtures. The drive mechanism for AGC
stages is a precision gear and matched worm that are preloaded to reduce backlash.
All AGC stages include optical limit switches and hard stops to define a ±45°
range of travel. Innovative direct feedback technology yields stable performance
and negligible performance drift over the life of the stage. This is in stark
contrast to other designs that must be continually adjusted to compensate for
worm wear. All stage tabletops feature hard coated aluminum, with stainless
steel Heli-Coil® inserts to prevent thread wear.
Flexible Options
Options include flexible motor selections as well as a direct encoder mounted
along the stage travel to offer outstanding repeatability and to minimize hysteresis
and backlash. Vacuum-compatible versions, for use in pressures as low as 10-6
torr, are also available.
A Complete Motion
Solution
Standard AGC stage configurations feature Aerotechs brushless servomotors,
while stepper and brushed motors are available. Aerotech offers a complete motion
solution by offering advanced single and multi-axis motion controllers, linear
and PWM drives, calibration and performance documentation, and all accessories
necessary for your system.
