• Introduction：

Zinc Selenide (ZnSe) crystal is a yellow transparent polycrystalline material with a light transmission range of 0.5-15μm. Due to the small absorption of 10.6μm wavelength light, it is known as the material of choice for optical devices in high-power CO₂ laser systems. Zinc Selenide crystal material has a high ability to withstand thermal shock. When used as a high-power laser device, it is necessary to use the least destructive polishing technology and the highest optical quality coating process. ZnSe is widely used in laser, medicine, astronomy and infrared night vision and other fields.
