(25.4 mm) wave plates, polarizers, and beamsplitter cubes. Precise, 100 TPI adjustment screws on the tip/tilt mechanism feature new knobs with an integral hex hole to allow adjustment with increased sensitivity. Independent locks for each axis help maintain stable optical alignment. The integrated rotation stage has a full ball bearing race providing continuous 360° rotation with graduations marked in 2° increments. Tightening the screw on the end of the knob securely locks rotation.
