ZnSe Protective window

Zinc selenide protective windows are protective components commonly used in infrared optical systems, characterized by the following features: 1. Broadband transmission: They exhibit high transmittance in the wavelength range of 0.6μm to 22μm, particularly suitable for 10.6μm CO₂ laser systems, effectively transmitting infrared light signals. 2. Low absorption and low dispersion: With a low absorption coefficient, they minimize signal attenuation, and their good dispersion characteristics reduce chromatic aberration and signal distortion in optical systems. 3. Thermal shock resistance: They can operate stably within a certain temperature range, making them suitable for scenarios involving thermal effects such as high-power laser applications. 4. Mechanical properties: The material is relatively soft (Knoop hardness approximately 120), requiring attention to avoid scratches and mechanical impacts; they are typically used with protective coatings or special installation methods.
