Overview of CVD ZnSe Window
CVD zinc selenide window are made from zinc selenide (ZnSe) material synthesized through chemical vapor deposition (CVD). ZnSe is a yellow-transparent polycrystalline material known for its high purity, strong environmental adaptability, and ease of processing. It exhibits low optical transmission loss and excellent transmittance, making it particularly suitable for high-power laser systems.
Features of CVD ZnSe Window
CVD ZnSe windows exhibit high transmittance in the 600 nm to 16 �¼m wavelength range, making them well-suited for infrared spectroscopy applications.
Material Characteristics:
High Purity: The material boasts high purity, strong environmental adaptability, and ease of processing.
Low Absorption: It features a low absorption coefficient of less than 0.0005 cm^-1 at a wavelength of 10.6 �¼m.
Thermal Shock Resistance: The material has excellent thermal shock resistance, making it ideal for high-power CO2 laser systems.
Low Hardness: Due to its relatively low hardness, ZnSe is prone to scratches and typically requires a high-hardness anti-reflective coating for protection.
Applications for CVD ZnSe Window
High-Power CO2 Lasers:
Due to its high purity, strong environmental adaptability, ease of processing, and low optical transmission loss, CVD ZnSe is the optimal window material for industrial high-power CO2 lasers.
Infrared Applications:
CVD znse lenses excels in infrared applications, making it suitable for thermal imaging, FLIR (Forward-Looking Infrared) systems, and medical systems. Its low absorption coefficient and high resistance to thermal shock make it widely used in these systems.
