Antireflective coating is also known as anti-reflection film, and its major function is to reduce or eliminate the optical surfaces such as lens, prism, level crossing
Reflected light, so as to increase the light transmission capacity of these elements, reduce or eliminate the veiling glare of system.
Simplest anti-reflection film is monofilm, and it is relatively low thin of one layer of refractive index being plated on optical element optical surface
Film.If the optical thickness of film layer is a quarter of a certain wavelength, the optical path difference of adjacent two-beam is exactly π, i.e. vibration side
To on the contrary, the result of superposition makes optical surface reduce the reflected light of the wavelength.Thin-film refractive index is suitably selected, at this moment optics table
The reflected light in face can be completely eliminated.
Generally, preferable antireflective effect is extremely difficult to using single layer anti reflective coating, in order to realize that zero is anti-in Single wavelength
Penetrate, or the antireflective effect reached in wider spectral regions, often using double-deck, three layers even antireflective coating of more layers number.
Antireflective coating is a kind of optical thin film most widely used, that yield is maximum, and therefore, it is still optical film technique so far
