Quartz Polarization Rotator
Due to the rotation activity of natural quartz crystal, it also can be used as polarization rotators so that the plane of input linearly polarized beam will be rotated at special angle which is determined by the thickness of quartz crystal. Left-handed and right-handed rotators can be offered by Tuniu Optics now.
- Made of quartz, 200-2500 nm
- Up to 100 mm diameter
- Custom rotation angle available
