Thin Film RefractoMeter

The thin film refractive index tester calculates the refractive index by measuring the deflection angle of light passing through the film. It is used to determine the optical properties of thin films and is applied in quality control within the optical coating, semiconductor, and display panel industries.
Selection
When selecting, consider the film thickness range matching the instrument's measurement range. Choose ellipsometry or reflectance measurement based on transparent or semi-transparent materials. Confirm the measurement accuracy and repeatability specifications, and check whether temperature and humidity environmental compensation functions are supported.
