Spectral Transmittance Meter

A spectrophotometric transmittance meter operates by emitting a light beam of a specific wavelength through a sample. The detector receives the intensity of the transmitted light and calculates the percentage of light transmission. It is used to measure the light transmission properties of materials such as plastic films and glass, and in quality control to determine whether the transparency of the material meets the required standards.
Selection
When selecting, confirm that the measurement wavelength range covers application requirements, and ensure that the sample size matches the instrument fixture. Pay attention to measurement accuracy and repeatability indicators, and check whether they comply with industry testing standards. The instrument's operation interface should be simple, and the accompanying calibration tools must be complete.
