Abstract

The main problem with manufacturing of large convex mirrors is in their optical testing that requires high-precision optical components with clear diameters exceeding the mirror under the test. To avoid this problem there is a side illumination scheme, in which a narrow collimated beam propagates normal to the axis of the testing mirror. Wavefront reflected from the mirror contains information about shape of the mirror. Different methods to analyze the wavefront reflected are discussed. A lens raster wavefront analyzer is developed.
