一、前言光学仪器在使用和贮存过程中,一种严重的危害是光学元件遭受到,湿热、霉菌、盐雾等自然环境因素的腐蚀。多年来,对这个问题国内外光学仪器研制工作者都给予了极大的注视。为了制造具有“双防”或“三防”性能良好的光学仪器,工作者们考究了许多方法,探索了许多具有双防或三防性能的新材料,用于提高光学仪器的使用寿命。目前,据我们了解,在光学元件上涂双 I. Introduction Optical instruments in use and storage process, a serious hazard is the optical components suffered, damp heat, mold, salt spray and other natural environmental factors corrosion. Over the years, this issue has given great attention to the development of optical instruments at home and abroad. In order to create optical instruments that perform well with “double or triple” defenses, workers have studied many ways and explored many new materials with double or triple guards to increase the useful life of optical instruments. At the moment, as far as we know, double the optics
