10 Precision Balls for use with the PSM for alignment and assembly of optical systems.
Description
These 0.5” (12.7 mm) diameter chrome steel balls are Grade 5, the best quality available as a commodity item. The balls are round to 125 nm with a surface finish of 1.25 nm rms. The balls are near diffraction-limited convex mirrors with a reflectivity of about 65%. They are ideal for use with the PSM in transferring optical to mechanical datums, and vice versa to better than 1 µm. Typically, the balls are supported on the ends of lens posts used as kinematic mounts. Where the mounting surface is not horizontal, use the magnetic nests listed under ball/nest pairs.
