Laser Thickness Measurement System

Laser thickness gauges measure thickness by emitting a laser beam onto the surface of a material and calculating the time difference or phase change of the reflected light. They are used for real-time measurement of materials such as films, coatings, and plates, and are applied in production lines and quality inspection processes.
Selection
When selecting, consider the measurement range covering the sample thickness, accuracy meeting inspection requirements, material surface characteristics compatible with the laser type, environmental factors such as vibration and temperature effects, device response speed matching the production line pace, and an operation interface that is simple and user-friendly.
