Aerotech’s APR series rotary stages employ precision-machined and ground stage parts coupled with high-precision angular contact bearings and an Aerotech direct-drive motor to produce exceptionally low error motions, accuracy errors, and repeatability errors. The addition of high-resolution optical encoders provides excellent pointing capability with low-jitter velocity tracking.

Applications
APR stages are ideal for rotary testing, pointing, optical calibration systems, and metrology systems in applications including single and multi-axis electro-optic sensor testing, resolver or optical encoder accuracy testing, missile seeker testing, antenna testing, inertial navigation device testing, photonic component alignment, high-accuracy laser machining, and precision wafer inspection.
