Achromatic Depolarizers

An Achromatic Depolarizer consists of two wedged prisms made of birefringent materials with their fast axes aligned at 45 deg to each other, and one of the prisms is twice as thick as the others. Achromatic depolarizers transform polarized light into a pseudo-polarized state, which means the polarization of the incident beam is randomized rather than being converted into a complete unpolarized state.
