ZnS can be divided into raw ZnS and multispectral ZnS. Multispectral ZnS is grown by the chemica vapor deposition (CVD) process.Multispectral ZnS is obtained from native ZnS through a hot isostatic pressing treatment. ZnS has a transmission range covering visible and infrared light. Multispectral ZnS features high hardness and strong resistance to wind and sand erosion, and is widely applied in the manufacture of lR windows and lR optical components.
