: / ) There are usually two small holes on the lens of a smartphone for the light sensor and distance sensor. of infrared penetration. There is also a slightly larger hole for the camera. The infrared penetration ability of these two small holes in the lens directly affects the performance of the light sensor and distance sensor of the smartphone. All this infrared transmittance index is very important.
The main plane of the lens, the camera hole, and the light and distance sensor holes also have light transmittance index requirements.

: / ) bThe testing principle is to use infrared light source, infrared light source and visible light source to illuminate the transparent substance to be measured, and the sensor detects the incident light intensity of the three light sources and the transparent substance to be measured respectively. The light intensity behind the substance, the ratio of the transmitted light intensity to the incident light intensity is the transmittance, expressed as a percentage
