Hindhivac manufactures wide range of Scientific Coatings. For an untreated optical element, there is always some reflection at each air to surface interface. The amount of reflected energy is a function of the index of refraction of the optic. The anti-reflection coating preserves the image quality and conserves the transmission energy. This coating is used in a wide variety of applications such as Camera lenses, Instrument panels, Binoculars, Cover glasses and Telescopes. They can be deposited on flat, concave and convex surfaces with extremely good spectral uniformity.
