Zinc sulfide (ZnS) optical window
PRODUCT CATEGORIES
Zinc sulfide (ZnS) is divided into two materials, one is a white multispectral material and the other is a yellow primary material. It is a chemically inert material with the characteristics of high purity, insoluble in water, moderate density and easy processing. Due to the wide transmission band (500-10000nm) of zinc sulfide (ZnS), it is widely used in the manufacture of infrared windows, fairings and infrared optical elements.
