Digital light meter LS108D

0.5mm small test aperture, Free PC software 850/940nm IR transmission and 550nm VLT Three data can be obtained by one test Real-time dynamic self-calibration function LS108D lens transmission meter is professionally used for mobile phone lens transmittance test and IR hole infrared transmittance test. The test aperture is 0.5mm, which can test 550nm visible light transmittance and 850nm, 940nm infrared ray transmittance. The lens transmission meter has a real-time dynamic self-calibration function. It will automatically calibrated to 100% transmittance after powering on. This lens transmission meter has a test aperture of only 0.5mm and has wide application. The test principle of the lens transmission meter is that the light source illuminates the transparent material, the sensor detects the incident light intensity of the three light sources and the light intensity after passing through the measured transparent material. The ratio of the transmitted light intensity to the incident light intensity is the transmittance, expressed as a percentage. Measuring Aperture - ￠0.5mm (standard) Infrared - peak wavelength 850nm/940nm Visible Light - peak wavelength 550nm Resolution - 0.1% Measurement Accuracy - ±2% (colorless uniform transparent material, 0-90% transmittance) Weight - 1570g Dimension - 170mm × 180mm × 144mm (L*W*H) Display - 480px * 272px color LCD Power Supply - DC 5V/1A The test aperture of this lens transmission meter is 0.5mm. Materials whose size are larger than 0.5mm can be measured The three light sources share a test hole.
