Spectrum-Based Thickness Gauge

The spectral thickness gauge calculates the thickness of coatings or thin films by measuring the reflection or transmission characteristics of a material's surface to light of different wavelengths, utilizing the principle of spectral interference. It is used to measure the thickness of film layers in industries such as coatings, inks, and plastics, ensuring that products meet specification requirements.
Selection
When selecting a spectral thickness gauge, considerations should include the measurement range covering the sample thickness, accuracy meeting process requirements, probe size fitting the measured area, compatibility with material types, user-friendly operation interface, data output format matching the existing system, environmental interference resistance, maintenance costs, and calibration cycle.
