Abstract

The present report is devoted created interferometer for large convex optical aspheric surfaces. The testing method is also presented. It is based on an orthogonal ray scheme, where the convex testing surface is illuminated by a collimated beam, that is perpendicular to the optical axis of the surface. The interference pattern is formed on a screen by the interaction of the reference beam passing over the test surface and the object beam reflected from the test surface. The interference pattern is a system of quasi-straight fringes, containing information about the shape of the tested surface as the distance between those fringes. The experimental data obtained on the interferometer and presented.
