Miniature rotary stages are compact, accurate and economical
Aerotech's MPS-GR series rotary stages provide accurate, repeatable positioning in a miniature, low-profile and economical package. Available in two sizes - the MPS50GR and MPS75GR - they are engineered for both the confines and requirements of a laboratory setting as well as for 24/7 industrial manufacturing. MPS-GR stages are suitable for optics, measurement, alignment, inspection and other demanding applications.
Each MPS-GR stage incorporates a precision worm-gear drive and bearings for accurate and repeatable positioning. They are available with DC servo or stepper motors and either a 20mm (MPS50GR) or 30mm (MPS75GR) clear aperture. The clear aperture enables the MPS-GR stages to be used for applications requiring a through-hole or mountings for optics, including articulation of beam polarising lenses, through-holes for cabling or air lines, or vision/camera/inspection applications. The DC servomotors for the MPS-GR stages are equipped with a square-wave rotary encoder and the MPS75GR includes a manual adjustment knob.
MPS-GR rotary stages provide performance of up to 80 arc-seconds accuracy, 1 arc-second resolution, 6 arc-seconds repeatability and 180 degrees/s maximum speed. Maximum load capacity is 12kg and tilt error motion is 40 arc-seconds.
Vacuum applications
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) makes it easy to mount standard lenses over the stage aperture.
The MPS50GR and MPS75GR are members of Aerotech's MPS (Miniature Positioning Stage) family of linear, rotary, goniometer and vertical-lift stages. It is easy to mount two or more stages together in numerous combinations using standardised mounting patterns with adapter plates and brackets. In addition, Aerotech manufactures a wide range of positioning stages, drives and controls to provide a fully integrated and optimised motion solution.
