Optical coating is a mixture of thin layers of films that produce interference effects to improve transmission & reflection properties of an optical system. These coatings are manufactured with oxides, metals, and rare earth materials. The performance of optical coating depends on the number of layers, thickness of different layers, coating material, and the difference in refractive index at the layer interface.
