LS108D lens transmittance measuring instrument Introduction: LS108D lens tester is applicable to the transmittance test of lenses and infrared transmittance test of IR ink holes. The test aperture is 0.5mm, and can test the transmittance of 550nm visible light and the transmittance of 850nm and 940nm infrared. The instrument has a real-time dynamic self-calibration function, which automatically calibrates to 100% transmittance after startup. LS108D uses an infrared 850nm light source, an infrared 940nm light source and a visible 550nm light source to illuminate the transparent material to be measured. The sensor detects the incident light intensity of the three light sources and the light intensity after passing through the transparent material to be measured. The ratio of the transmitted light intensity to the incident light intensity is the transmittance, which is shown with a percentage table. characteristic: 1. The minimum test hole size of this lens transmissivity tester is ￠ 0.5mm, which can be measured for materials with aperture larger than 0.5mm. 2. The three light sources share a test hole, and have LED light for alignment indication, which is convenient for hole alignment during testing. 3. The real-time dynamic self-calibration function of the instrument automatically calibrates to 100% transmittance after startup. 4. Large LCD display, three display interfaces can be selected, and the infrared transmittance of 850nm and 940nm can be selected to display both or only one of them. 5. The instrument is provided with computer software, which has the function of judging whether it is qualified or unqualified, and can quickly detect materials and improve production efficiency. Technical parameters: Measuring beam diameter: ￠ 0.5mm Infrared: peak wavelength 850 nm and peak wavelength 940 nm Visible light: peak wavelength 550nm Resolution: 0.1% Measurement accuracy: ± 2% (colorless and uniform transparent material, 0-90% transmittance) Instrument weight: about 1570g Overall dimension of the instrument: 170mm long × 180mm wide × Height 144mm Power input: DC5V/1A
