anti-reflection coating | Also 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. |
coronene | The first ultraviolet phosphor to be tried on the surface of a CCD. |
Lumogen | Fluorescent 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. |
