Abstract

Leta Nanie

In this paper, the theoretical calculation of the characteristics of the optical film, including the basic theory of the film, the calculation of the characteristics of the single-layer film, and the calculation of the characteristics of the multilayer film, to achieve a certain degree of understanding of the characteristics of the optical film. And through the optical anti-reflection film The design principle, material selection, and process mastering have a deeper understanding of the anti-reflection film. The transmission spectrum is used to calculate the “envelope method” The refractive index, thickness, absorption coefficient, an extinction coefficient of the film to analyze the optical performance of the film.
