Feature: 1. 3 Channel Wavelength Test: The transmission meter adopts wavelength synthesis technology, one optical hole simultaneously tests 3 channel wavelength data 2. High Efficiency: The transmittance of 550nm, 850nm and 940nm can be obtained in one hole alignment, which greatly improves the test efficiency 3. Indication LED: The test hole has alignment indication LED, which is used in the test process to help the hole alignment of the tested lens, convenient for operation 4. Automatic Calibration: The tester has real time dynamic self calibration function, which automatically calibrates to 100% transmittance after power on 5. Large LCD Display: The UV lens transmittance tester is equipped with a large LCD screen, convenient for reading datas 6. Application: This transmission tester is specially used for infrared transmittance and visible light transmittance test of mobile phone lenses Specification: Item Type: Lens Transmittance Tester Material: Stainless Steel and Electronic Components Model: LS108A Infrared: Peak wavelength 850nm and peak wavelength 940nm two way test Visible Light: Peak wavelength 550nm Measuring Aperture Diameter: Approx.1mm Resolution: 0.1% Measurement Accuracy: ±2% (colorless all have light transmitting substances, 0-90% transmittance) Plug Type: US plug 100-240V. Package List: 1 x Lens Transmittance Tester1 x U Disk1 x Plug1 x Data Cable1 x Manual Note: 1. The instrument is self testing and self calibrating when turning on, no test objects can be placed in the test position, otherwise the self calibration cannot be completed.2. Avoid contact with corrosive items and keep away from high temperature and high humidity environment.3. When there is no test object, the transmittance data cannot be returned to 100% occasionally, the instrument can be used normally after shutting down and restarting immediately without affecting the measurement accuracy.4. Please turn off the instrument when not in use.5. When the interface is abnormal voltage interface, please replace the power supply.
