The test principle is that four light sources with different wavelengths irradiate the transparent material, and the sensor detects the incident light intensity and the light intensity of the light source passing through this transparent material. Then, the ratio of the two data is regarded as the transmittance, which is displayed in percentage.
It is mainly used to test the optical performance of transparent materials such as eyeglasses lenses, sunglasses, anti-blue light materials, coating materials, and organic materials etc.
