Anti-reflective Coating, Multilayer

Application ID: 19279

The simplest example of an anti-reflection coating is a quarter-wavelength layer. One big disadvantage of such a single-layer coating is that there is generally no practical material with the required refractive index to achieve a low reflectance. A combination of several layers can be used to reduce the reflection coefficient over a much wider range of wavelengths than a single layer while allowing a wider variety of real materials to be used. In this model, a quarter-quarter and a quarter-half-quarter structure are modeled.

This model example illustrates applications of this type that would nominally be built using the following products:
