Nirmal Optronics (P) Ltd.

Optical flats are mainly used for the measurement of the surface flatness of polished surface for checking the flatness using monochromatic light source.

The main applications of optical flats are listed below:

• Calibration of flatness of various optical surface.

• Inspection of gauge blocks

• Testing of filters, mirrors, and prisms

• Spectrophotometry

It is mainly used ins in automobile, aerospace optical and in calibration labs. In optical industry, it is used to check the flat-ness of a surface such windows, prisms, etc. The surface flatness requirement varies to application to application. Monochro-matic light source such as sodium vapour lamp which has a single wavelength is used to create sharp contrast fringe pat-tern to check the flatness.

Optical flats are available in optical material such as N-BK7 equivalent glasses. Fused Quartz Optical Flats quote will be pro-vided against specific requirement.
