FMD Lamp/Optical Flat

The Hyprez® FMD lamp is the most advanced flatness measurement device, replacing a conventional helium lamp. A green light (wavelength: 5,461 Å) backs up the optical flat to clearly indicate a fringe pattern on a mirror surface. Also, it can take a clear photograph of the fringe pattern with ASA400 film.
