Abstract

Perfect testing of optical prism elements for a laser interferometer is based on interference measuring methods complying with strict requirements concerning the choice of optical elements for systems of coherence optics. Interference testing methods for measurements of the absolute angular deviation of optical surfaces forming the right angle and measurements of corner-cube prisms with the unambiguous determination of the angular deviation of the functional part of individual sectors of the measured prism are described.
