The compact Ultra Precise Rotational Stage (UPRS-2D1F-001) is a positioning device for ultra-precise rotational orientation, along two orthogonal rotational axes, of photonics or other components. Its frictionless design allows for ultra-precise positioning without hysteresis and backlash.

The heart of the UPRS-2D1F-001 is our patented fine rotation Flex Plate. The range of rotation of the UPRS-2D1F-001 Flex Plate is 480 μrad (1500 stepper motor steps) with a resolution of 0.3 μrad/step. The Flex Plate can be customized with ranges and/or resolutions to fit customer needs.

Two coarse positioning motors provide a range of 0.2 radians with a resolution of 33 μrad/step (6,000 stepper motor steps). The course positioning can be customized with ranges and/or resolutions to fit customer needs.
