第一胶片厂质检科工程师牟秀芳等同志,采用新技术,经过三个月的努力,使原来的光楔质量有重大突破,生产出了高质量的标准光楔,为我国胶片感光测定实现标准化作出了贡献。标准光楔是胶片感光仪中控制不同曝光量的主要元件,由一系列不同密度值的石墨层组成。在感光测定检验中,就是靠标准光楔做成试片光楔,再通过测算来绘制胶片的感光特性曲线的。感光材料
The first film factory quality inspection department engineer Mou Xiufang and other comrades, the use of new technologies, after three months of hard work, so that the quality of the original wedge a major breakthrough in the production of high-quality standard optical wedge for our film standardization Made a contribution. Standard optical wedge is a film photometer in the control of different exposure of the main components, by a series of different density values of the graphite layer. Sensitivity test in the test, is made by the standard optical wedge test wedge, and then through the calculation of the film to draw the photosensitive characteristics of the curve. Photosensitive material
