Simultaneous characterization of the quality and orientation of cylindrical lens surfaces

摘要

A diffractive grazing-incidence interferometer for the test of cylindrical lenses is described. Besides surface aberrations from the ideal shape, the interferometer allows for the simultaneous determination of the relative position and orientation of surfaces to another. The measurement principle as well as a classification of deviation types is given. Measurement results for planar concave lenses are presented. (c) 2005 Optical Society of America.
