Abstract

A numerical method for synthesis of achromatic antireflection coatings on dielectric and metal surfaces in the visible and infrared regions of the spectrum is considered in this paper. Metal and dielectric films are used in the coatings created in the required spectral range. Antireflective coatings with different requirements for the spectra of reflection and transmission in the spectral ranges of 0.3–0.8 µm and 5–15 µm are synthesized. To analyze the possibility of the implementation of the coatings, we study the stability of the synthesized structures with respect to errors in the thickness of the films used during the manufacture.
