45° Elliptical ZnSe Polished Window
For the dedicated scenarios of 45° optical path beam splitting, beam calibration, and infrared imaging, we introduce the 45° elliptical zinc selenide (ZnSe) polished window, using a high-purity substrate + ultra-precision polishing process to solve the industry pain points of conventional round windows such as optical path obstruction, poor adaptability, and high optical loss, providing high-performance optical support for mid-infrared laser systems, scientific research detection, and industrial equipment. It adopts high-quality CVD-deposited zinc selenide material with high purity and very few impurities, reducing scattering loss from the root. It has extremely low absorption in the CO2 laser band, is heat-resistant and impact-resistant, and can stably adapt to high-power laser working environments. Different from conventional round lenses, the dedicated 45° elliptical special-shaped structure precisely matches the angled optical path design, effectively avoiding equipment structural interference and maximizing the use of clear aperture. The standard 45° tilt angle has controllable precision and a stable beam splitting ratio, with no offset in optical path transmission and no stray light interference, perfectly adapting to the assembly requirements of compact, high-precision optical equipment.
