Abstract

Some experimental qualitative results are presented with a setup that uses a knife edge for producing partial interferograms, in order to obtain the quality of a lens under test. However, the same method can be extended to test an optical surface. The knife edge is located near the focal point of the lens, covering almost half of the incident laser light beam. The different observed interferograms correspond to the orientation of the knife edge with respect to the optical axis, and its distance to the focus of the lens.
