Light Transmittance Measurement For Lens Glass UV 365nm IR 940nm VL 380nm-760nm

Light Transmittance Measurement For Lens Glass UV 365nm IR 940nm VL 380nm-760nm Introduction : spectrum transmission meter is a desktop instrument, which is exclusively designed for optical transmittance test of various materials such as lens, glass, coating material, organic material and paint, etc. The test aperture of the meter is 1mm, which is suitable for the measurement of light transmittance, infrared and ultraviolet transmittance of small

size materials. The flat bench-top meter is available for placing various test samples. The test is fast and accurate. Once the test material is placed on the meter, the test results will be displayed immediately. The meter use parallel light path design that can measure thick materials. The optical transmittance tester use ultraviolet light source, infrared light source and visible light source to illuminate the transparent material. The sensor detects the incident light intensity of the three light sources and light intensity after passing through the transparent material under test. The ratio of the over light intensity to the incident light intensity is the transmittance shown in percentage. Application It is suitable for measuring the transmittance of various uniform transparent materials, such as glass, PC, coated glass, IR hole on the remote control window, plastic, paint, lens, organic glass (acrylic), etc. Parameters Parameter Value UV peak wavelength 365nm IR peak wavelength 940nm Visible light 380nm-760nm full wavelength,in line with CIE photopic luminosity function Resolution 0.1% Measurement accuracy ±2% (colorless uniform transparent material, 0-90% transmittance) Minimum test sample

size ￠ 1mm Dimension 170 mm ×180 mm ×144 mm (L*W*H) Weight about 1570 g Power supply DC5V/1A Features Three light sources share a test hole, which can obtain 380nm-760nm visible light transmittance, 940nm infrared and 365nm ultraviolet transmittance in one measurement, easy to operate and save time. Parallel light design enables stable and accurate results on testing large thickness materials. The test aperture is 1mm, applicable to test transmittance of small-sized materials. The light transmission meter has a real-time dynamic self-calibration function, which automatically calibrates to 100% transmittance after startup. It is suitable for the transmission test of lens, paint, glass, mobile phone lens, organic material, etc. Large LCD display, Chinese and English interface can be selected.
