Optical Flats

Optical Flats provide the fast, sure and accurate method of obtaining flatness measurement under Monochromatic Check-lite. It is always necessary to have reflective, clean and dry surface of finished component before measuring its flatness. Flatness measurements are accomplished by reading interference (light) bands which appear on the surface of the work piece when placed under a optical flat. Fringes appear when the flat is placed gently on work piece surface under Monochromatic Checklite. The optical flats are available in various diameters.
