What Are Light bands? Light bands formed by using an optical flat and a monochromatic light source represent an inexpensive yet accurate method of checking surface flatness. The monochromatic light on which the following diagrammatic interpretations are based comes from a Sodium filled tube source which eliminates all colours except a ...
There are a number of ways to measure the flatness of a surface. The most common method within the Flat Lapping sector is by using a Monochromatic Sodium light unit and an Optical Flat. This gives extremely precise measurements, more accurate than most CMM measurements, in an economical way.

Lapmaster Wolters Monochromatic Lights are used to measure surface flatness within millionths of an inch. These self-contained units use a helium light tube to produce a glare free light of known wavelength (23.2 millionths of an inch).
Produced from Quartz, Kemet Optical Flats are available in single and double sided, 1/4 light band or 1/10 light band accuracy. Special optical flats are available on request. Kemet offers an optical flat reconditioning and calibration service.
An optical flat is a contact optical measurement device used in conjunction with a monochromatic light source to measure precision flat surfaces. Lapmaster optical flats are manufactured from high quality fused quartz.
Van Keuren monochromatic lights use a helium source with a light of 23.13 millionth wavelength (587.6 mm) and are available in three styles. Our lights are made with fine woods. *Call for pricing on Models L-1A and L-2A.
