The Preparation And The Analysis Of Characters Above The Windows Of Infrared Detector

The infrared window is a key device about the military system。 Only are the proper material and structure chosen,the good infrared windows can be made,at the same time,the demand of military and detector must be considered。 The parameter is designed according to the systematic method。The method of research is introduced and the characters are analyzed above the infrared windows in this paper。 The compound of KBr and PE or the compound CsI and PE is discussed in the paper, the working range is between fifteen micrometer and fifty micrometer,the material is a kind of Alkalescent-bittern compound and polyethylene,which belongs to inorganic-organic composite meterial and the meterial has good quality。 The material is used widely in the far-infrared optical windows and lenses。 Heat-press method is used in this paper,the method has a lot of merits,such as simply manipulating,quick confection and short period。 Only are the proper velocity,appropriate temperature and the good press chosen well,the infrared window can be made well.The temperature of working is controlled under the one hundred and fifteen centigrade。 The mean transmission rate is under percent fifteen from one micrometer to fifteen micrometer and above percent fifty from fifteen micrometer to fifty micrometer according to the testing result。 The mechanical intensity can arrive the best when the diameter is ten times the thickness of infrared window。...
