Michelson (2.5X and 5X) and Mirau (10X, 20X and 50X) Objectives Available Infinity Corrected 200mm Tube Lens Design Interferometry bives are used in non-contact optical profile measurement devices to obtain surface maps and surface measurement beters. They can be used to examine surface topography with very high precision—to within a frb of the wavelength of light. In these bives, a light beam passes through a beamsplitter, which directs the light to both the surface of the sample and a built-in reference mirror. The light reflected from these surfaces recombines and a fringe interference pattern is bed. The Michelson bives provide comparatively longer working distances, wider fields of view and larger depth of focus, whereas the Mirau bives are used in applications requiring higher magnification and/or numerical apertures. Use of the Nikon 200mm tube lens (#58- 520) allows these bives to be integrated to a C-Mount camera.
