LS108D Lens Transmission Meter Introduction
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 power-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 measured 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.
