CRYLINK thin film polarizer is protected by two N-BK7 window plates. The contact surface between the window plate and the air is coated with antireflective film. In addition, because the polarizer is very sensitive to stress, in order to prevent improper installation from affecting the performance of the polarizer, the thin film polarizer is installed in a metal clasp, which is suitable for low-power applications and can achieve ultra-high extinction ratio. The edge and front of the metal clasp of the polarizer are engraved with product model and polarization direction marking line, which is convenient for customers to identify and use.
