    • Zinc Selenide Wedge Windows

    Zinc selenide wedge windows have a wedge-shaped design, used to separate the interior and exterior of optical systems, protect internal devices, and change the deflection path of light. It has characteristics such as high transparency, high anti reflection, and high thermal stability. It has high transmittance in both visible and infrared bands, as well as low reflectivity and low absorption. It can be coated with reflective film, anti reflective film, filter film, spectroscopic film, polarizing film, and metallization film systems.
