Using laser scanning, spectral confocal microscopy, capacitance method, eddy current method, photo-thermal method, and other measurement techniques, YZS Precision has developed various film thickness measurement systems. We offer mature measurement solutions for wet films, dry films, coatings, plating films, and more.
1. High-Precision Motion Platform
*XYZθ Multi-axis Combined Motion Solution
*Repeat positioning accuracy up to 0.1μm
*Automatic focusing function
*Automatic triggering of optical system for
image acquisition
We independently design and manufacture high-precision multi-axis motion platforms for film thickness measurement systems, with customizable motion range options.
2. Error Compensation Algorithms
*Geometric Error Compensation for Motion
Mechanisms
*Equipment Temperature Compensation
*Calibration Error Compensation
Professional compensation algorithms that address geometric errors in motion mechanisms, temperature variations, and calibration errors, achieving high precision.
3. Multiple Measurement Methods
*Spectral Confocal Method
*Laser Triangulation Method
*Capacitance Method
*Eddy Current Method
For different types of measured film materials, we employ different measurement methods. For transparent films, we use spectral confocal microscopy; for metal coatings, we utilize eddy current testing, etc.
4. Self-developed Motion Controller
*Multi-axis Motion Control
*Direct Input of Probe Data into Controller
*Support for EtherCAT Communication
*Support for Multiple Probe Connections
Probe data can be directly input into the
controller via EtherCAT protocol, significantly
enhancing real-time data acquisition from the
probes. Various commonly used probes can
be connected to the controller.
