Optical Transmittance Meter

An optical transmittance meter measures the transmittance of a material by shining a light source onto it and detecting the ratio of transmitted light intensity to incident light intensity. It is used to evaluate the light transmission capability of transparent or translucent materials, such as in industries like coatings, plastics, and glass, to assess material transparency and uniformity.
Selection
When selecting an optical transmittance meter, it is essential to consider whether the measurement range matches the material's transmittance, if the accuracy meets standard requirements, whether the sample size is compatible with the fixture, if the ease of operation suits the usage environment, and to refer to the brand's reliability and maintenance services.
