CRYLINK’s quartz Lyot depolarizer converts a polarized beam into a pseudo-random polarized beam. Regarding Linearly polarized beam from a monochromatic source, the output beam is converted to pseudo-depolarized beam with polarization state varies spatially. Linearly polarized beam comes from a broadband source which is transmitted through a quartz Lyot depolarizer will have a polarization that varies spatially as well as with wavelength. CRYLINK’s quartz Lyot depolarizer consists of two crystal quartz wedges, the thickness of one is twice of the other. The optical axis of each wedge is in the plane of aperture, the orientation angle between two optical axes is 45°. The unique design of the quartz Lyot depolarizer does not require orienting the optical axes of a depolarizer at a specific angle, which is especially useful where the initial polarization state of the light is unknown or varies with time.
