摘要
基于机载光电设备红外窗口的性能要求,对几种8～12μm波段红外材料的性能进行了比较,分析ZnS材料作为长波红外窗口的优越性,并对两种不同工艺制备的ZnS的光学、力学和热性能进行了分析和比较,对以ZnS为基底的窗口材料的镀膜选择进行了分析.介绍了一种红外窗口厚度的确定方法,并对不同厚度及镀膜前后的ZnS样品进行了透过率的测试.
The property requirements of infrared window for the airborne photoelectric equipment has been explained and the properties of the material for 8 ～ 12μm infrared region have been compared. The superiorities of gnS as a material long wave infrared window were descrobed, and gnS optics, mechanics and hot function of two kinds of different crafts are analyzde and comparde. The choice of window material coating on the gnS has been analysed, and the method of ascertain lng the thick of infrared window has been introduced. The transmittance of gnS has been compared between different thickness and coating or not.
