Modified polarizing prism

We accomplish the production of linearly polarized light by modifying our earlier design of a non-deviating dispersion prism for three cases by setting, (i) the angle of incidence equal to the inverse of the cotangent of the refractive index (n), (ii) twice the angle of incidence equal to the angle of refraction plus the inverse of the cotangent of the refractive index (n), and (iii) the angle of incidence equal to the difference of twice the inverse of the cotangent of the refractive index (i?), and the angle of refraction. Finally, we present a design for an achromatic polarizer using a penta prism. These designs and their salient features are discussed in the light of Cervantes' review and other polarizers. Some possible applications are given. (C) 1998 Elsevier Science Ltd. All rights reserved.
