Quatz Silica Wedge Depolarizer

This DQW series of depolarizer consists of a crystalline quartz wedge together with a compensating fused silica wedge to correct the angular deviation.The optic axis of the quartz wedge lies in the plane of the wedge and at 45 deg to the input polarization.The result is then a variable retardation plate over the aperture,which produces depolarization for all wavelengths.So,this DQW depolarizer is thus effective with monochromatic light.
