45° elliptical zinc selenide polished window
For specialized scenarios of 45° optical path beam splitting, beam calibration, and infrared imaging, we launch a 45° elliptical zinc selenide (ZnSe) polished window, using high-purity substrate + ultra-precision polishing process to solve the industry pain points of conventional circular windows such as optical path obstruction, poor adaptability, and relatively high optical loss, providing high-performance optical accessories for mid-infrared laser systems, scientific research detection, and industrial equipment. It uses high-quality CVD-deposited zinc selenide material with high purity and very few impurities, reducing scattering loss at the root. It has extremely low absorption for the CO2 laser band, is heat-resistant and impact-resistant, and can stably adapt to high-power laser working environments. Unlike conventional circular lenses, the exclusive 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 accuracy is controllable, the splitting ratio is stable, and optical path transmission has no offset and no stray light interference, perfectly adapting to the assembly needs of compact and high-precision optical equipment.
