AR Coating
Of all the possible applications,antireflection coatings have the greatest impact on optics.
AR Coating can reduce surface reflection. In some applications,it is necessary to eliminate
ghost images or veiling glare.
AR coating can be a single layer having virtually zero reflectance at just one wavelength,also a multilayer system of more than one layer,having virtually zero reflectance over aspectrum range. The type used in any particular application will depend on a variety of factors ,including the substrate material,the wavelength region,the required performance and the cost.
