With a resolution better than 0.011° and an overall thickness of just 0.63" (16.0 mm), the compact Picomotor™ Rotary Stages can be used for a number of applications, including positioning wave plates and polarizers . Each rotary stage includes an adapter for mounting components with a 1" (25-mm) diameter. For motorized beam-steering applications, use our 45° adapter model 9922. For applications requiring high accuracy and repeatability, the 8410 Closed-Loop Picomotor Rotary Stage includes an encoder for superior position feedback. The closed-loop version provides microradian level of precision and continuous 360° rotation.

The central aperture of the stage is 1.563-20 threaded through a 0.62 inch depth. It can directly hold 1.5 inch diameter optic using two  retaining rings. Each stage also comes with two adapters for mounting components with a 1 inch (25.4 mm) or 0.5 inch (12.7 mm) diameter. For motorized beam-steering applications, use our model  45° mounting adapter.
