硫化锌(ZnS)是一种重要的红外光学材料，在8~10μm波段范围内拥有较高的透过率，广泛应用于导弹整流罩、红外天文卫星、红外光谱仪、测量仪和热像仪等领域。采用高温后处理工艺方法可促进晶粒生长，并起到消除热压多晶ZnS内部的残余六方相和气孔的作用，进而可提升材料光学透过性能。对于厚度5 mm的热压ZnS试验片，1.064μm处透过率达到60%，2~10μm平均透过率达到73%。经后处理的光学窗口其抗冲击性能测试结果表明，材料保留了原有热压ZnS材料的力学特性，且在400益的条件下能够满足光电探测系统清晰成像的要求。

Zinc sulfide (ZnS) is an important infrared material because of its optical characters in 8-10μm. It is widely used in the area of missile dome, infrared astronomical satellite, infrared spectrometer, measure instrument and thermal imager. The high temperature treatment make hot-pressed ZnS crystal develop, therefore, hexagonal ZnS and crystal pores are eliminated in the polycrystal ZnS samples. The infrared transmittance is increased. The average transmittance of post-treatment ZnS sample is 73% in the range from 2μm to 10μm, and 60% at 1.064μm, with 5 mm in thickness. The thermal shock resistance test results that the post-treatment ZnS reserve mechanics characters of hot-pressed ZnS before, and it make optical-electro detecting system imaging clarity through post-treatment ZnS window at 400℃.
