Thick-Film Coatings

TERMS
antifog coating A coating that is capable of stopping the condensation of moisture on an optical surface.
antireflection coating A thin layer of material applied to a lens surface to reduce the amount of reflected energy. Ideally the index of refraction of that material should be equal to the square root of the product of the indices of the material on either side of the...
dielectric coating A high-reflectance coating consisting of alternating layers of quarter-wave film of a higher refractive index and lower refractive index than the substrate. Such coatings can be made very specific to a reflected wavelength or, by varying the layers'...
hard coating Usually a dielectric coating on glass or plastic optics; a coating that is comparable in hardness to glass itself.
multilayer coating A coating made up of many layers of material having alternating high and low refractive index. In this way, it is possible to produce coatings with a great variety of properties. These may be spectrally high-pass, low-pass, bandpass, antireflection...
