Abstract

The new methods for antireflection of optical surfaces with use of the transition layers and diffraction gratings, is researched. The optimal profile of refractive index variation for transition layer is determined. For antireflection of the boundary ldquotransparent dielectric-airrdquo the relief diffraction grating is shaped on surface of dielectric. The profiles of grating groove that minimize of reflectance, is searched.
