The Möller-Wedel Optical Micro-Interferometer VI-direct extends the range of flatness testing to the domain of smallest diameters. The Fizeau-type interferometer is able to measure the surface flatness of optical parts with a diameter between approx. 0.8 mm to 3.6 mm. The cost effective Micro-Interferometer VI-direct can be used for testing of optical parts like micro-prisms, laser crystals, fiber endings etc.
