AG-PR100 is a polarizer rotator which features 360° continuous rotation for 1" diameter waveplates and polarizers. This high precision unit features Newport’s new Agilis piezo step direct motor which provides ultra-high adjustment sensitivity and convenient remote operation. The Agilis piezo motor is directly coupled to the moving carriage with no intermediate screw or gear. Precision motion is achieved by a proprietary ball-bearing that ensures better than 100 μrad wobble. When idle, the holding force of the motor locks the position for true set-and-forget, long-term stability.

The AG-PR100 offers all the benefits of a motorized component in an ultra-compact, lightweight casing, at a price comparable to that of a high quality manual stage. Compared with alternative screw-driven designs, it compromises neither adjustment range nor lifetime, and has no backlash.
