Abstract
Experimental studies have been carried out to evaluate the refractive indices of zinc selenide single crystals of the same type ZnSe CVD from different batches in the spectrum range of 1.3-25 μm. A technique for determining refractive indices based on the spectrophotometric method using the reflection and transmission spectra of the plates and the reflection spectra from the sample surface is presented. The results of the study showed not only the correctness of the proposed methodology, but also the fact that the obtained performance indicators for different samples of zinc selenide from different batches in the investigated part of the infrared range differ more from each other than indicated in reference books, which should be taken into account when developing products of transmission optics.
