(Aerotech: Pittsburgh, PA) -- Aerotech Inc. is a designer and manufacturer of motion control, positioning tables/stages, and positioning systems. Its 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. 

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. Multiple APR stages can be combined for high-accuracy azimuth/elevation or azimuth/roll systems. Vacuum-prepared and other customized versions are available for specialized applications.
