The LS183 spectrum transmission meter use ultraviolet light source, infrared light source and visible light source to illuminate the tested transparent material. The sensor detects the light intensity of the three light sources and the light intensity after transmitting the ...
1. Three light sources share a test hole, which can obtain 380nm-760nm visible light transmittance, 940nm infrared and 365nm ultraviolet transmittance in one measurement, easy to operate and save time. 2. Parallel light design, the measurement results of testing large thickness ...
1. The test aperture of this lens transmission meter is 0.5mm. Materials whose size are larger than 0.5mm can be measured. 2. The three light sources share a test hole. Three data can be obtained by measuring for just one time. Easy to operate and save time. 3. The test hole ...
