Abstract
A simple and inexpensive technique for obtaining the interference microtopographs of crystal surfaces is reported. The method consists of forming a low angle air wedge by placing a thin glass sheet (cover slide) on the surface of the sample. Interferograms are taken under reflected sodium light.
