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.) Current smartphones generally have two small holes, one for sensing light and one for sensing distance. The infrared penetration ability of these two small holes will directly affect the performance of the light sensor and the distance sensor. So usually we will use a lens transmittance tester to detect its transmittance.
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 test. The sensor detects the incident light intensity of the three light sources and the light intensity after passing through the transparent material under test. 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.
