Recently, the technology research and development department of Chengdu Zhongke Weishi Instrument Co., Ltd. has independently designed and completed the task of developing optical film thickness intelligent measurement and control devices.
The traditional optical coating uses the extreme value method to monitor the film thickness. Correctly determining the extreme point is an important operating technique for coating operators, which determines the quality of each coating. During the coating process, the coating operator must pay full attention to the change in the film thickness relative value displayed by the film thickness monitor in order to correctly determine whether the thickness of this layer is reached. Since the number of coated layers of an optical element is often several to several tens of layers, it is quite labor-intensive for a coating person. For a long time, scientists and technicians have been looking for ways to overcome this phenomenon.
Only real company developed "Intelligent light control film thickness monitor" can correctly and automatically give the extreme points, not only to reduce the labor intensity of the coating operator, but also greatly improve the quality of the coating. The introduction of this monitor to the market to replace the original controller will have great economic and social benefits, and it will be applicable to a large number of mid- to low-grade coating users, with large market capacity and considerable benefits.
