Depolarizers are used where a linearly polarized light is undesirable such as with polarization sensitive devices. The depolarizer converts the polarized input into a pseudo-randomly polarized output. Our depolarizers are optically contacted and AR coated for high power operation. Lyot depolarizers consist of two quartz waveplates one being exactly twice the thickness of the other and assembled with their optic axes 45° apart. This combination creates various degrees of elliptical polarization as a function of wavelength and therefore, Lyot depolarizers cannot be used with monochromatic beams. |
