Abstract:

This paper discusses the features of methods of testing aspheric primary mirrors of telescopes with lens-based, mirror–lens-based, and holographic correctors. Methods are described for simultaneously testing the same surface of an optical item with different correctors to achieve and confirm the required parameters of the aspheric (vertex radius and conic constant). Results are given for testing the correctors with a holographic mirror simulator to verify the fabrication accuracy of the correctors themselves and, if necessary, of the wave-front correction of the lens correctors.

Keywords:
