Our company has two IR Ink Transmission Meter LS108A and LS108D, they are mainly applied in mobile phone lenses and infrared ink industry, and later a customer has applied these two instruments in the infrared filter strip industry. Today we mainly introduce the new method of IR ink transmission meter.
The Linshang LS108D mobile Lens transmission meter is used to test the transmittance of the distance and position sensing holes. The LS117 optical density meter is used to test the optical density of the screen printing ink.
The quality of the lens is mainly judged from the three aspects of light transmission, anti-blue light effect and anti-violet light effect. The lens transmission meter is used to detect the lens quality.
The instruments used in the mobile phone glass transmittance test are mainly LS108A and LS108D lens light transmission meters. And we will give a detailed introduction about the two lens light transmission meters.
The IR hole of the proximity sensor on the cover of the mobile phone and the light transmission hole of the light sensor have certain requirements on the light transmittance. The measurement of the two light transmission holes can be measured by using the mobile phone IR lens transmission meter
