南通光学仪器厂自己设计、研制的我国第一台使用激光进行无损检测的仪器——JJJ-1型激光定焦仪在南通市通过省级鉴定。参加会议的有来自国内有关科研所和压力容器生产厂等近20个单位的代表,其中有:上海锅炉厂高级工程师马铭刚、上海光学仪器研究所总工程师陆汉民、江苏省锅炉设备公司总工程师蔡诗国、江苏省机械设计院主任工程师孟沪龙等。 JJJ-1型激光定焦仪采用He-Ne激光器发出的激光束代替不可见的X射线,捕捉检测目标清晰、形象、直观,它能精确、快速、方便地显示或选择工件的透视中心(指向),测定或选择透视焦距(定焦),还能协助确定被探容器中心。
Nantong Optical Instrument Factory own design, development of China’s first non-destructive testing using laser instruments - JJJ-1-type laser focusing device in Nantong City, passed the provincial appraisal. There are representatives from nearly 20 units including research institutes and pressure vessel manufacturing plants in China, including: Ma Minggang, Senior Engineer of Shanghai Boiler Works, Lu Hanmin, Chief Engineer of Shanghai Institute of Optics and Instrumentation, and Cai Shi Guo, Chief Engineer of Jiangsu Boiler Equipment Company , Jiangsu Province, Mechanical Design Institute director Meng Hailong and so on. The JJJ-1 Laser Focusing System uses a laser beam emitted by a He-Ne laser instead of invisible X-rays to capture a clear, vivid image of the inspection target. It displays, or selects, the center of the workpiece accurately, quickly and easily ), Determine or select the perspective focal length (fixed focus), but also to help determine the center of the probe being explored.
