LS116 Light Transmittance Meter

S116 light transmittance tester is a professional instrument for testing the light transmittance of uniform light-transmitting materials. It uses a parallel light path design and can also be used to detect large thickness materials with an accuracy of ± 1% which is to ensure passing the testing of the metrology Institute. Light transmittance is an important technical indicator of many optical products, such as glass, solar film, laminated glass, PC plastic, etc. The test principle of the light transmittance meter is to use a visible light source to illuminate the measured substance. The sensor detects the incident light intensity of the light source and the light intensity after passing through the measured substance. The ratio of the transmitted light intensity to the incident light intensity is transmitted. Rate, expressed as a percentage.
