AAS-1原子吸收仪是东德蔡司出厂的仪器,这种仪器国内有一定数量。该机的外光路部分有几块反射镜片,虽然安装在机壳内。但由于长期暴露于实验室潮湿气氛之中,经年累月,镜片镀膜层腐蚀严重。以我们所使用的仪器为例,镜面从表面看去,布满大大小小霉斑,这样必将引起测试光束在传输光路中的损失。为此,于1983年4月,将图1中的反射镜1,2,3进行了维修,重新镀铝膜。因原仪器所附说明书有关这方面内容不详,工作中一边摸索一边干,实践证明这一方法是有效的。
AAS-1 atomic absorption instrument is the East German Zeiss factory equipment, there are a certain number of such instruments. The machine outside the light part of the road there are several pieces of reflective lenses, although installed in the chassis. However, due to long-term exposure to the humid atmosphere in the laboratory, over the years, serious corrosion of the lens coating. Take the instrument we used as an example, the mirror surface is covered with large and small mold spots, which will surely cause the loss of the test beam in the transmission light path. To this end, in April 1983, the mirror 1, 2, 3 were repaired, re-aluminized film. Due to the original instrument attached to the manual on this aspect is unknown, while working to explore while dry, the practice proved that this method is effective.
