Paper Abstract

In an optical shop, during the process of manufacture of optical surfaces, is necessary the testing of the surfaces until to obtain the quality required; there are traditional techniques divided mainly in two groups: the geometric tests (Ronchi, knife, etc.), and inteferometric tests (Newton, Fizeau, etc.). When the surfaces are aspherical, it is difficult to use these techniques, because is required an elaborate experimental arrangement for the surface under test, and is necessary to use an auxiliary optics with the same or superior optical quality them the surface under test. In this work we introduce a new method for testing conic surfaces using a Fizeau interferometer, without auxiliary optics o compensators, in particular we applied this testing to a paraboloidal surface.
