The detection of coating thickness will help to effectively control the thickness uniformity of each film. However, for multilayer films, if we want to accurately measure the thickness of each layer, we need to invest a lot of money in the corresponding thickness detection equipment, and it will increase with the growth of the film layer, which will bring greater economic burden to enterprises. The more economical way is to test the coating thickness of some expensive coating materials, and at the same time strengthen the test of the overall thickness of the film to effectively control the thickness uniformity of other layers of materials.
For film thickness measurement, Shenzhen Dacheng Precision has been increasing R&D investment and constantly committed to technological innovation. Dacheng Precision Optical Interference Thickness Gauge The optical interference thickness gauge specially developed for transparent films can well measure the thickness of single-layer or multi-layer transparent films. It has high precision and wide application, and is especially suitable for thickness measurement of transparent multilayer objects with nanometer thickness requirements.
