The detection of coating thickness will be conducive to the effective control of the thickness uniformity of the film layers, but for multi-layer film if you want to accurately measure the thickness of each coating, in the corresponding thickness testing equipment will need to have a very large investment, and with the increase in the number of layers of film and increase the economic burden on the enterprise. The more economical way is to part of the expensive coating materials for coating thickness testing, while strengthening the overall thickness of the film to achieve the overall thickness test to achieve effective control of other layers of material thickness uniformity of the role.
For film thickness measurement, Shenzhen Dacheng Precision has been continuously increasing investment in research and development and constantly committed to technological innovation. Dacheng Precision Optical Interference Thickness Gauge developed specifically for transparent film optical interference thickness gauge can well realize the thickness measurement of single-layer or multi-layer transparent film. Extremely high precision, wide range of applications, especially suitable for thickness measurement of transparent multi-layer objects requiring thickness up to the nanometer level.
