rotary aperture stage, 2.0" optic

RSA series rotation stages with an aperture for polarization applications provide smooth, continuous angular positioning for a variety of components. Aperture versions come with two Delrin® retaining rings to securely hold optics without damage. RS series rotation stages use our unique integrated bearing design. This ball bearing design is a robust but cost-effective alternative to more expensive bearing packages. Our knurled drive system coupled with the bearing system ensures smooth positioning throughout the full 360° of continuous rotation.
