A ZnSe window is a high-performance, chemically vapor-deposited optical element designed for demanding infrared applications. These windows provide an expansive transmission range from 0.5 μm to 22 μm, making them essential for high-power CO2 laser systems and thermal imaging. Engineered for durability, they offer exceptional resistance to thermal shock and maintain ultra-low IR absorption to prevent thermal lensing and energy loss.
