coating comparison table
Subject has definition
anti-reflection coatingAlso AR coating. A layer of material of lower refractive index of just the right thickness (1/4 wave) is deposited on the optical surface to be coated. More complex coatings are possible which cover a large wavelength range.
coroneneThe first ultraviolet phosphor to be tried on the surface of a CCD.
LumogenFluorescent UV coating which improves the blue sensitivity of a CCD by emitting light at approximately 540 to 580 nm when excited with light of wavelengths shorter than 450 nm.
