Zinc selenide right-angle prism is a high-performance optical component designed for superior infrared transmission, exceptional chemical stability, and minimal absorption. Manufactured from high-purity ZnSe, it offers outstanding optical clarity, precise light redirection, and excellent mechanical durability. This prism is widely used in infrared imaging systems, laser optics, aerospace applications, and precision scientific instruments, ensuring accurate beam manipulation and reflection in advanced optical assemblies.
Product Overview
The Zinc Selenide (ZnSe) right-angle prism is an optical element made from high-quality ZnSe material, widely used for optical path deflection and image deviation. This prism can deflect the image formed in an optical system by 90°, making it ideal for beam displacement, image combining, and other applications requiring precise control of optical paths. ZnSe, as an excellent optical material, offers good transmission and low absorption across a wavelength range of 600 nm to 16 µm, ensuring high performance across ultraviolet, visible, and infrared spectra.
The prism also features excellent thermal shock resistance and high stability, maintaining stable optical performance even in high-temperature environments. Its unique 45° and 90° angular design makes installation more convenient, while providing strong mechanical stress resistance.
