Optical Cell Kinematic Mounts provide highly stable kinematic movement with two axis tilt (pitch and roll) provided by a precise ball pivot adjustment and an orthogonal three-point suspension. Adjustment is made by three 64-pitch screws (two 64-pitch screws for 1-2" diameter model). Adjustment is made by two 64-pitch screws for 6" diameter model and three 32-pitch screws for 8" up to 12.5" diameter models. Fine pitch screws permit 50% greater resolution than a micrometer. Angled base allows for stand-alone installation and mounting. These mounts have integral optic cell design allowing optics to be held undistorted.
