>> Product Description
1.Optical performance: It has good transparency, a wide transmission band, generally between 0.5 μ m-22 μ m, high transmittance throughout the entire transmission band, low scattering, and low optical transmission loss.
2. Physical properties: Zinc selenide is a yellow crystalline powder, insoluble in water, non hygroscopic, isotropic in material, and free from birefringence. Its density is 5.26g/cm ³, with a Mohs hardness of about 2.5 and a Knoop hardness of 120. The texture is relatively soft and prone to scratches.
3. Chemical properties: The chemical properties are relatively stable and it is a chemically inert material, but it easily decomposes and emits harmful hydrogen selenide gas when exposed to acid.
4. Thermal performance: With high thermal conductivity, it has a high ability to withstand thermal shock and can withstand rapid temperature changes without breaking.
>> Application
1. Laser system: Due to its low absorption of 10.6 μ m wavelength light and its ability to withstand the thermal effects caused by high-power lasers, it has become the preferred material for producing optical components such as mirrors, beam splitters, and windows in high-power CO2 laser systems.
2. Infrared imaging: In thermal imaging systems, infrared night vision devices, and other equipment, zinc selenide window plates can allow infrared light to pass through, providing a clear optical path for imaging. They are widely used in security, industrial testing, and other fields.
Spectral analysis: In infrared spectrometers, it is used as a window to allow specific wavelength ranges of infrared light to pass through, for qualitative and quantitative analysis of substances.
3. Medical field: Infrared optical components that can be used in medical instruments, such as infrared diagnostic equipment, laser treatment equipment, etc., to assist doctors in disease diagnosis and treatment.
4. Astronomy: In astronomical observation equipment, it is used for observing the infrared band, helping astronomers study the infrared radiation characteristics of celestial bodies.
