Aerotech’s MPS-GR series feature precision worm-gear drive with DC servo or stepper motor.
Aerotech introduced its MPS-GR series rotary stages. Available in two sizes — the MPS50GR and MPS75GR — the stages incorporate precision worm-gear drive and are available with DC servo or stepper motors and either a 20 mm (MPS50GR) or 30 mm (MPS75GR) clear aperture. The DC servomotors for the MPS-GR stages are equipped with a square-wave rotary encoder and the MPS75GR includes a manual adjustment knob.
The MPS-GR rotary stages provide performance of up to 80 arc seconds accuracy, 1 arc second resolution, 6 arc seconds repeatability and 180 degrees per second maximum speed. Top load capacity is 12 kg and tilt error motion is 40 arc seconds. Both stages are available with optional vacuum preparation to 10-6 torr including a vacuum-rated motor/feedback connector. An optional breadboard mounting plate provides direct mounting to both English and metric optical tables and a Lens Mount Option (LMO) permits easy mounting of standard lenses over the stage aperture.
