Annotation
Peculiarities of synthesis of broadband coatings for separation of achromatic light in the spectral range of 1,5—25 microns to be used in Fourier spectrophotometers of intermediate and far IR, are considered. Methods for the synthesis of multilayer coatings and the stability analysis of coatings are developed. The films are created from materials based on Ge and ZnS, the optical constants of Ge and ZnS films are determined in the spectral range from spectrophotometerс data with the use of correction of optical spectra for absorption. Two synthesized multilayer coatings with 4 and 5 layers are tested. The both coatings meet the requirements and are recommended for the use as coatings for separation of achromatic light for Fourier spectrophotometers of intermediate and far IR. Comparison of the coatings in the required spectral range demonstrate a higher resistance of the 4-layer coating to errors in the layers, has the smaller criterion of stability and feature quality, and is easy to manufacture. intermediate and far IR.
