WebIn contrast to the antireflection film, the reflectivity of the optical surface can be increased by plating a film with a refractive index higher than the base material on the optical surface. The simplest multilayer reflection is formed by alternating evaporation of two materials with high and low refractive index. WebIn contrast, dielectric thin-film coatings operate by utilizing optical interference. A simplified schematic of how this works is shown in Figure 1, which depicts a light ray incident upon a material having a single-layer thin film on its surface. Part of the ray energy is reflected at the air-coating interface, and part of it is transmitted ... side effects when you get off of azathioprine
