(Aerotech: Pittsburgh) -- Compact, low-profile MPS-GR rotary stages from Aerotech, designer and manufacturer of precision motion control products, provide accurate, economical positioning for both laboratory and industrial applications. Clear apertures of 20 mm or 30 mm allow the stages to be used effectively where through-holes are required. These applications include articulation of beam polarizing lenses, through-holes for cabling or air lines, or vision and camera inspection.

Designed for 360° measurement, alignment, and inspection in optics, photonics, and lasers, the stages incorporate a precision worm-gear drive mechanism and bearing components. They are available with DC servo or stepper motors. Accuracy is up to 80 arc seconds, resolution is 1 arc second, repeatability is 6 arc seconds, and maximum speed is 180° per second. Top load capacity is 12 kg.
