1. Wide spectral transmission range: Zinc Selenide has good transmission in the wavelength range of 600 nm to 16 µm (even up to 21 µm), especially in the mid-infrared region (2-12 µm).
2. High refractive index: At a wavelength of 10.6 µm, its refractive index is 2.403, which is suitable for manufacturing high-precision optical components.
3. Low absorption rate: Low absorption in the infrared band, suitable for high-power laser systems, such as CO₂ lasers.
4. Good environmental adaptability: high purity, chemically inert, able to maintain stable optical properties in a variety of environments.
5. Thermal shock resistance: Able to withstand rapid temperature changes, suitable for high-power laser optics.
