The LS183 Optical Transmittance Meter is a professional instrument for testing the optical transmittance of light-transmitting materials such as glass, coated materials, organic materials, coatings, and solar films. The instrument uses ultraviolet light source, infrared light source and visible light source to irradiate the transparent material under test, and the sensor detects the incident light intensity and the light intensity after passing through the transparent material under test. The ratio of the transmitted light intensity to the incident light intensity is the transmittance, expressed as a percentage.
