High precision film thickness monitor for high vacuum evaporation coating machine

The working principle of the CY high-precision film thickness controller involves technologies such as photomultiplier tubes, optical systems, vibrating slits and DC signals. These components work together to enable the film thickness controller to achieve precise control of film thickness. Specifically, the photomultiplier tube is used to detect the growth of the film, the optical system ensures the accuracy and efficiency of the detection, the vibrating slit is used to control the flow of the evaporated material, and the DC signal provides the necessary control signal. The CY film thickness controller has a wide range of application value and important technical advantages in the field of film preparation and quality control.‌‌‌‌

CY film thickness controller is a device used to accurately control the thickness of vacuum evaporated metal or non-metallic films. It can accurately measure and control the thickness of coatings, coatings and films, thereby ensuring the accuracy and quality of surface treatment processes. It is mainly used in magnetron sputtering coating machines, high vacuum evaporation coating machines, electron beam evaporation systems, PLD pulsed laser sputtering deposition equipment, multifunctional thin film deposition systems, etc.

Features:

1.High precision：Thickness controllers can provide high-precision measurement results. For example, high-precision film thickness gauges use imported high-quality sensors with a thickness measurement resolution of up to 0.1 microns, ensuring the stability and accuracy of the test results.

2.Wide application：The film thickness gauge is suitable for measuring the thickness of a variety of materials and products, including metals, plastics, ceramics, glass, etc. This is because these materials are good conductors of sound and can achieve high-precision detection services. In addition, the film thickness gauge can also be equipped with a variety of dual crystals with different frequencies and different chip sizes to achieve efficient product thickness measurement.

3.Intelligent control：LCD display, simple operation, equipped with USB interface, can record, store, print data and connect to computer and printer.

4.Small size：small and beautiful appearance, simple and easy to operate, long service life.
