越来越多的现代照相机采用“钢片快门”作为控制摄影曝光量的时间控制机构,这是因为钢片快门机构作为一个完整组件,可以进行专业化生产。因此在规范的工艺及技术标准监督下,钢片快门的质量可以批量监控,这样制造成本可以大大降低,相机的使用质量也可充分得到保证。凤凰光学股份 More and more modern cameras use a “steel shutter” as the time control mechanism for controlling the amount of exposure to photography because the steel shutter mechanism as a complete unit can be professionally manufactured. Therefore, under the supervision of standard technology and technical standards, the quality of the steel shutter can be monitored in batches, thus the manufacturing cost can be greatly reduced and the quality of the camera can be fully guaranteed.
