随着光学刻度技术的发展,对感光化学及材料的研究和应用巳显得非常重要。在工业照相领域,从标牌制作、印刷制版、量具刻度、印刷线路、光学刻度、全息照相乃至电子工业的大规模集成电路,都与感光材料密切相关。作为记录介质和中间掩膜的感光材料,种类繁多,工艺各别。它们可通过照相系统缩微各种图形,也能和母板接触复制各种分划。不同的感光膜层依靠光化学反应能记录精密刻划机械投影图形或接触式光刻图形,加工出明暗不同、正反各异的刻度模板,并
With the development of optical scaling technology, it has become very important for the research and application of photochemical chemistry and materials. In the field of industrial photography, everything from plate making, plate making, gauging, printed wiring, optical scales, holography and even the electronics industry to large scale integrated circuits are all closely related to photographic materials. As a recording medium and the mask of the photosensitive material, a wide range of different technology. They can microfilm various graphics through the camera system, as well as being able to come into contact with the motherboard to replicate various divisions. Different photosensitive layer relies on photochemical reaction can be recorded precision lithography mechanical projection graphics or contact lithography graphics, processed out of different shades, positive and negative scale template, and
