Abstract

We developed a new interferometric method of measuring the wedge angles of beamsplitters and the deviation angles of penta prisms. This method could easily be extended to certify the angles on other optical pieces as well. We built the interferometer and analyzed the images using equipment that we already had in the lab, including a helium-neon laser, a CCD camera, framegrabbing computer hardware, and standard optical components.
