<p>A polarization independent optical device capable of eliminating the apparent polarization dependence of a dielectric multi-layer film (24) and permitting the design of an optical path at an optional angle of incidence of light beam. The polarization independent optical device comprises a tapered double-refractive crystal disposed so that an optic axis thereof is perpendicular to an incident optical path, and a dielectric multi-layer film (24) disposed on an exit side of light beam with respect to the tapered double-refractive crystal (26). <IMAGE></p> |
