Abstract

A heterodyne interferometer was developped to be used in the visible and in the infrared. If the RMS wavefront error is used to determine a datum focal plane, MTF measurements differ by less than 3% from calculated values for two special test lenses. The interferometers are compared to other MTF measuring techniques.
