LS108A lens transmission meter is mainly used to measure IR ink hole of mobile phone lens. (It is also suitable for infrared ray transmittance testing of various products that use infrared technology, such as remote control windows, IR cut, etc.) The LS108A lens transmission meter use an infrared 850nm light source, an infrared 940nm light source and a visible 550nm light source to illuminate the transparent material under testing. The sensor detects the incident light intensity of the three light sources and the light intensity after passing through the transparent material. The ratio of the incident light intensity is the transmittance, expressed as a percentage. The test aperture is 1mm. Measured object whose size is greater than 1mm can be tested. Three data can be measured at a time.

Three-in-one light source path design

Three light sources share a test hole and are equipped with alignment indicator LEDs for auxiliary alignment. Three data can be measured at a time

Three parameters can be measured at once, Three dispaly interfaces are available

The spectrum transmission meter can measure the 550nm visible light transmittance and the 850nm and 940nm infrared transmittance

Small test aperture, widely applicable

The aperture of test hole is 1mm, and the meter is not only suitable for measuring the transmittance of the IR ink hole of the mobile phone lens but also for the infrared transmittance test of various products with infrared technology, such as the remote control window and IR cut filter

Provide powerful computer software support

The light transmission meter is equipped with computer software, which can export the test results to the software. It can also use the computer software to judge the PASS/NG and count the number of tests. Using Type-C double-sided pluggable interface, you can also connect to computer software

Using large LCD screen for easy reading

Real-time dynamic self-calibration function, which automatically calibrates to 100% transmittance after turning on

5V mobile power, easy to connect

  1. 1. The difference between LS108A and LS108D

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