Advanced Quartz Lyot Depolarizer

This DAQ series of depolarizers is an improved Quartz Lyot Depolarizer,which consists of two quartz crystal wedges with their optic axis lying in the plane of the plates,and aligned at 45° to each other.It has the advantages of both Lyot and Wedge Depolarizer.One plate of the two quartz wedge is exactly twice the thickness of the other.The result is then a variable retardation plate over the aperture,which produces depolarization for all wavelengths.By this specially designed structure,we can get much better depolarization result than DQW type.
