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.

Small test aperture, widely applicable

The test aperture of this lens transmission meter is 0.5mm. Materials whose size are larger than 0.5mm can be measured

Three-in-one light source path

The three light sources share a test hole. Three data can be obtained by measuring for just one time and the test hole has an LED light for alignment, which is used to align the hole with the mobile phone lens during the test

Real-time dynamic self-calibration

The transmission meter has real-time dynamic self-calibration function which can automatically calibrated to 100% transmittance after starting

  1. 1. The difference between LS108A and LS108D

    The only difference is the measuring aperture (detector hole diameter). The measuring aperture of LS108A is 1mm, while the measuring aperture of LS108D is 0.5mm. Since the measuring aperture of LS108D lens transmission meter is smaller, so it is more suitable for measuring small-sized materials.
