China Optical Low-Order Waveplate Low Order Waveplate Optical Waveplate

>> Product Description
Waveplates (retardation plates or phase shifters) are made from materials wInsulation hich exhibit birefringence. The velocites of the extraordinary and ordinary rays through the birefringent material varies inversely with their refractive indices.
Low-Order Waveplates are much better than the multi-order wave-plates because of its thinner thickness (less than 0.5 mm). Better temperature (38), Wavelength (1.5nm) and incident angle (4.5° )bandwidth and high damage threshold make it widely used in common application.
