OPTICAL SYSTEMS FOR REMOVAL OF POLARIZATION SPECTRA

In the article optical systems are presented that are developed by the authors and have been used for many years to remove the polarization properties of anisotropic molecules. Both systems are designed for visible and close to ultraviolet spectral regions. In this case, the double Fresnel parallelepiped plays the role of an achromatic quarter of the wave plate. They are used in the Jasco-20 dichrograph after the Pockels cell. As a result, the sensitivity of the device increases from to of the value of the differences in optical density.
