ZnSe, CVD material introduction:
The ZnSe synthesized by the chemical vapor deposition (CVD) method has substantially no impurity absorption, and the scattering loss is extremely low. A to of 10.6 [mu] low absorption to the wavelength of light m become producing high-power CO.'s 2 laser system optics first selected material.
Zinc selenide - a compound of II-VI, belonging to a wide band gap material, a yellow transparent polycrystalline material having a crystal grain size of about 70 μm, a light transmission range of 0.5-15 μm, and a melting point of 1520 °C. The refractive index is 2.408, and the transmission range is 0.45 μm-20 μm. It belongs to a long-wave infrared transmission material, and the transmittance is usually about 71.6% after 1 μm.
