1£®Brief Description£º

Pressing the polycrystalline zinc sulfide is zinc sulfide of high purity raw materials, pressed under high temperature vacuum conditions, a wide band of infrared optical materials with excellent optical properties of the infrared lens, the impact resistance and the mechanical properties of the overload good thermal properties. Since the sphere can be directly compressed into a variety of window radius of curvature and large-size panels, it is widely used in a variety of sizes infrared detector window. In addition, the product is a good quality coating materials.
