Polarizer

A polarizer is an important optical component that is widely used in laser systems to generate the linear

polarization laser. Foctek makes following polarizers with five materials, a-BBO, Calcite and YVO, Quartz

MgF, , suitable for the widest spectrum and high polarization purity applications.
