Abstract
The Fresnel rhomb is used for the production 0of 0cirularly polarized light. In this paper, we propose a set of two 45 -90 -45 prisms which is equivalent to the Fresnel rhomb. The analysis of polarization properties of such a set of prisms was done and it was found that fo orginary experiments on polarizatin, it may satisfactory to use two 45 -90- 45 prisms for producing the circularly polarized light. It is not necessary to fabricate a special prism i.e. the Fresnel rhomb with special angles. If the faces of the prisms are coated with antireflection coatings, a high degree of circularly polarized light is obtained. The polarization calculations were done and verified by experiment.
