The optical system is not coated, and due to interface reflection, the transmitted light energy is very weak, reducing the imaging quality and resolution of the system. Therefore, in order to solve this problem, it is necessary to plating AR T ≥ 98.6%. jpg on the surface of optical devices. An optical system subjected to antireflection treatment can not only improve transmittance, but also greatly reduce the energy of continuous reflection of light between components, improving image clarity.
In applications, in general, single wavelength antireflection uses a single or double layer film, dual wavelength or a certain band antireflection uses a multilayer film, and broadband antireflection designs can also use non-uniform films. In addition, the antireflection film design is also related to factors such as substrate material, antireflection band width, and coating cost.
