Determination of the Optical Parameters of Uniaxial Crystals with Allowance for the Imperfection of the Spectrophotometric Complex Elements

Abstract

The influence of the imperfection of a polarizer, an analyzer, and a photoelectron multiplier of a spectrophotometric complex on the intensity of light passed through a plane-parallel plate of a uniaxial transparent or absorbing crystal has been theoretically investigated. Expressions for calculating the birefringence and dichroism at different wavelengths are obtained and analyzed. It is established that the influence of the imperfection of optical elements is stronger for calculating the birefringence value, as compared with the calculation of dichroism.
