Surface accuracy means .surface quality and surface figure.
Surface quality includes scratches and digs. Surface figuring means surface flatness measured in fractional λ values of the wavelength used.
such surfaces found on micrometers, measuring machines, gage blocks, snap gages, ring seals, valve seats and precision flat lapped parts are measured using optical flats.
Who we are
The directors are associated with the precision optical field since 1984. From a Tiny Sector Unit at Ambattur Industrial Estate, Chennai, Tamil Nadu, India, it has grown to a Corporate Body under the name and style of NIRMAL OPTRONICS PVT Ltd in 2008
Optics: Manufacturing of precision optical components lenses and prisms in micro (from 6mm dia onwards ) to macro sizes of customers' requirement.
Optical flats from optical glass and optical silica at present up to the size of dia 100 mm with
We do not claim to manufacture all the optical components listed in the literature. We manufacture the most common ones. Our list is limited to some types of lenses and prisms.
In short, one type of products are from our manufacturing Centre.
