# HighPower Co2 Laser 90 Phase Si, Cu Mirror

HighPower Co2 Laser 90 Phase Si, Cu Mirror 90 degree Phase Retarder, also commonly called circular polarizer, are used to transform the laser's linear polarization into a circular polarization. It is generally used as last mirror prior to focusing lens.
