石英偏振旋光片
Polarization rotators offer 45deg or 90deg rotation at a number of common laser wavelength, the optical axis in a polarization rotator is perpendicular to the polished face of the optic. The result is that the orientation of in put linearly polarized light is rotated as it propagates through the device. Left-handed and right-handed rotators can be offered by MT-Optics,Inc.
