ABSTRACT:
A system for the automatic measurement of parameters of optical elements such as radii of curvature, thickness, power, index of refraction, and focal length including the radii of curvature of convex or concave optical surfaces such as those of lenses, molds, lathe turned optics, inserts, ball bearings or micro-optics. The system includes a computer for control, operator interfacing, and analysis, along with an optical head for providing signals from which parameters can be calculated.
