Scientific reports of Bukhara State University


Optical systems developed by the authors and used for many years to study the polarization properties of anisotropic molecules are presented. Both systems are designed for visible and close to ultraviolet spectral regions. In this case, the double Fresnel parallelepiped plays the role of the achromatic quarter wave plate. They are used in the Jasco-20 dichrograph after the Pokels cell. Causing the sensitivity of the device increases from deg·sm-1 to 3 the magnitude of differences of the optical density.
