Overview
LS108D lens transmittance measurement instrument is LINSHANG brand professional for mobile phone lens light transmitance test and IR hole infrared transmittance test instrument. The instrument has a test aperture of 0.5mm, can test 550nm visible light transmittance and 850nm, 940nm infrared transmittance, with real-time dynamic self-Adjustment, Automatic calibration to 100% transmittance after startup, wide range of adaptation.
Features
1. The minimum test hole size is φ 0.5mm, and materials larger than 0.5mm aperture can be measured
2. Three Illuminants share a test hole, and three data of 550nm visible light transmittance, 850nm infrared transmittance, and 940nm infrared transmittance can be obtained by one hole
3. The test hole has an LED light with alignment indication for the hole alignment of the mobile phone lens during the test
4. Real-time Dynamic Self-Adjustment, Automatic calibration to 100% transmittance after startup
5. Large liquid crystal display, 3 display interfaces to choose from, 850nm and 940nm infrared transmittance can be selected to display both or only one of them
6. With Type C double-sided pluggable USB interface, free computer software, which can complete the functions of inspection quantity, pass rate, qualified and unqualified judgment in the production inspection process
Principle
The test principle of the lens transmittance measurement instrument is that the Illuminant irradiates the transparent substance to be measured, and the sensor detects the incident ray intensity of the three Illuminant and the light intensity after passing through the transparent substance to be measured. The ratio of the incident ray intensity to the incident ray intensity is the transmittance, expressed as a percentage.
Steps
Automatic calibration to 100% transmittance
2. Align the lens of the mobile phone into the test hole, and use the alignment indicator LED light to align the hole.
3. Three data of 550nm visible light transmittance, 850nm infrared transmittance, and 940nm infrared transmittance can be obtained by one hole
4. Select the display interface and infrared transmittance Display mode as needed
5. Can be connected to the computer through the Type C interface, using supporting software for data statistics and analysis
