Newport MKS Optic Rotation Mount, Kinematic Tip-Tilt, 25.4 mm, 100 TPI M1-1PR

The M1-1PR Kinematic Polarizer Rotation Mount provides tip/tilt positioning for 1 in. (25.4 mm) wave plates, polarizers, and beamsplitter cubes. This mount combines the tip/tilt adjustments of a kinematic mirror mount with that of a polarizer rotation mount. It features precise, 100 TPI adjustment screws for tip/tilt adjustment with increased sensitivity. A rotation lock on the rotation mount helps maintain stable optical orientation. The integrated rotation stage has a full ball bearing race providing continuous 360° rotation with graduations marked in 2° increments. We've moved the scale to the same side as the knobs to make it easier to read during adjustment. Tightening the screw on the end of the knob securely locks rotation. Each unit is supplied with a Delrin retaining ring for mounting an optic. A 1/2 inch diameter polarizer or waveplate can be mounted to the M1-1PR mount using the PRA-05 Adaptor, which screws into the 1.063-20 thread. The PRA-05 Adaptor includes a retaining ring.
