Abstract

See full text

An optical test system and corresponding method disclosed herein provides highly accurate test data for both sides of a lens simultaneously and efficiently to analyze the surface topography and/or geometric parameters of a lens or lens system. More particularly, the optical test system and corresponding method moves the lens in test plane to align a plurality of points of a test pattern on a lens surface with a vertical axis while probes aligned with the vertical axis and on opposing sides of the lens simultaneously collect wavelength-specific data for both lens surfaces. The optical test system uses the collected wavelength-specific data to produce a surface topography and/or the associated lens geometric parameters for each lens surface.
