Construction Features

The MPS-GR stages incorporate a precision worm-gear drive mechanism and bearing components for highly accurate positioning performance over the lifetime of the product. They are available with DC servo or stepper motors. The DC servomotors for both stages are equipped with a square-wave rotary encoder. The MPS50GR has a 20 mm aperture and the MPS75GR has a 30 mm aperture. The MPS75GR includes a manual adjustment knob.

Vacuum and Mounting Options

Both stages are available with optional vacuum preparation to 10-6 torr including a vacuum-rated connector. An optional breadboard mounting plate provides direct mounting to both English and metric breadboards. Also available is an aperture Lens Mount Option (LMO) for easy mounting of standard lenses over the stage aperture.

The MPS50GR and MPS75GR are members of the MPS (Miniature Positioning Stage) family of linear, rotary, goniometer and vertical lift stages. Two or more stages can easily be mounted together in numerous combinations using standardized mounting patterns with adapter plates and brackets.
