The Yuzuki - 50 mm Optical Flat is a piece of optical glass that has been lapped and polished to be exceedingly flat on one or both sides, often to a few tens of nanometres (billionths of a meter). The 50 mm Optical Flat is used to measure various surfaces’ flatness (surface accuracy), whether optical, metallic, ceramic or otherwise, using a monochromatic light. When an Optical Flat is lit and put on another surface, light waves reflect off both the flat’s bottom surface and the surface it is sitting on. The Yuzuki - 50 mm Optical Flat
