This paper presents methods and facilities created at the State Institute of Applied Optics Scientific Manufacturing Organization, some fairly recently, for fabricating and monitoring off-axis aspheric optical elements. These methods are useful in the short-run optical production of such items. © 2011 Optical Society of America. Source

This paper proposes a setup for monitoring concave aspheric surfaces, using an axial synthesized holographic compensator with a spacing from the test surface greater than the vertex radius of curvature of this surface, and presents experimental verification that it is workable. This way of placing the holographic compensator is most convenient for monitoring concave aspheric surfaces with a moderate radii of curvature at the vertex, as is characteristic, in particular, of small-scale fast objectives. © 2011 Optical Society of America.

This paper discusses the features of using an interferometer to monitor the shape of concave parabolic and elliptical surfaces and presents results based on the properties of the anaberrational points of these surfaces. The interferometer brings about a single reflection of the rays from the test surface, and it therefore is suitable for testing aspheric surfaces that possess large deviations from a specified shape at the initial stage of their polishing. Such a situation is encountered when aspheric surfaces with large asphericity and slope are being shaped. © 2011 Optical Society of America. Source
