聚光镜是一个熔融石英制的透镜。它是隔离放置光学系统的真空室及电极架的小室之间的窗户。即把分光器的真空状态和外界空气隔开,所以对聚光镜主体板的表面加工精度要求十分严密,否则破坏真空室内部的真空度,就无法分析碳、磷、硫、硼、砷、锡。由于分析这些元素要位于2000以下的 The condenser is a fused silica lens. It is a window separating the vacuum chamber in which the optical system is placed from the chamber in the electrode holder. That is to say, the vacuum state of the optical splitter is separated from the outside air. Therefore, the surface precision of the main body of the condenser lens is very strict, otherwise the carbon, phosphorus, sulfur, boron, arsenic and tin can not be analyzed because the vacuum inside the vacuum chamber is damaged. Due to the analysis of these elements to be located below 2000
