ZnSe Windows

Zinc selenide optical windows are widely valued in optical engineering for their outstanding performance characteristics. They exhibit excellent transmission in the mid-infrared (mid-IR) spectral range—typically reaching 70–80%—making them ideal for high-efficiency infrared optical systems where maximum IR throughput is critical. Mechanically, ZnSe windows offer superior hardness and strength compared to many alternative optical materials, delivering enhanced resistance to physical impact and abrasion. Chemically, they demonstrate remarkable stability, maintaining integrity even in mildly corrosive environments. Furthermore, ZnSe lends itself well to precision fabrication: it can be readily machined, ground, and polished into a wide variety of shapes and dimensions to meet the exacting requirements of custom optical systems.
