贵钢1984年引进美国750V直读光谱仪,随机只有一块聚光镜,仪器经两年连续使用,造成聚光镜透光率逐渐下降,这直接影响了分析精度。如向国外申请购买,手续相当麻烦,申请外汇也很困难。为了保证仪器能正常投产使用,我们着手自行设计聚光镜,委托新光仪器公司加工。聚光镜主体板应由铝合金制成,此材料一时无法买到,我们用铜取代,透镜材料
In 1984, Guigang introduced the 750V direct-reading spectrometer in the United States. There was only one condenser at random. After two years of continuous use, the light transmittance of the condenser decreased gradually, which directly affected the analysis accuracy. To apply for a purchase abroad, the procedure is rather troublesome and it is also very difficult to apply for foreign exchange. In order to ensure that the instrument can be put into operation normally, we set out to design a condenser and commissioned Shin Kong Instruments. Condenser body panel should be made of aluminum alloy, this material can not be bought for a while, we use copper to replace the lens material
