Linshang Lens Transmission Meter Wide Application
Lens transmission meter is also called mobile lens transmission tester, lens transmission tester, etc. It is a professional transmission measurement instrument for measuring 850nm, 940nm infrared transmittance and 550nm visible light transmittance. It is mainly used for the detection of the transmittance of mobile phone lenses and the infrared transmittance of IR ink holes. It is also commonly used to detect various applications of infrared remote sensing technology for electronic equipment parts and infrared cut-off filters and other materials. Linshang Technology is a manufacturer of lens transmission meters. Currently, there are two models of lens transmission meters: LS108A and LS108D.
I. Lens transmission meter principle
The working principle of the lens transmission meter: when the light source illuminates the tested object, the sensor of the instrument detects the incident light intensity of the three light sources and the light intensity after passing through the tested object. The ratio of the transmitted light intensity and the incident light intensity is the transmittance, expressed as a percentage.

550nm, 850nm and 940nm transmittance test
III. Lens transmission meter by industry
Many industrial fields have requirements for the visible light transmittance and infrared transmittance of products. Therefore, a professional lens transmission meter is required for testing. In addition, smart homes and various electronic devices that have appeared in recent years will use infrared remote sensing technology, so Linshang lens transmission meter can be used not only to detect mobile phone lenses, but also for many other industries.
1. Used in mobile phone cover industry
Nowadays, smartphones can be said to be very popular. The measuring instruments of touch screens, IR inks, cover plates and other industrial instruments have also become popular. Such as lens transmission meter. The lens transmission meter is mainly used to detect the IR ink on the mobile phone lens, that is, the transmittance of the position and distance sensing hole on the cover plate, which is tested in the specified band in the industry. For European and American standards, the lens transmission meter mainly test the transmittance of mobile phone lenses at 550nm and 850nm, while for Japanese and Korean standards, the lens transmission meter mainly test the transmittance of mobile phone lenses at 550nm and 940nm. Different standard tests have different points. Linshang lens transmission meter can test the transmittance of 550nm visible light, 850nm infrared and 950nm infrared wavelength. It is widely used in the mobile phone cover industry.
2. Used in IR CUT industry
The so-called IR cut filter is the infrared cut filter, which is a filter used in the camera lens. Due to the need to cut off the infrared. Therefore, some customers will always ask the real data. At this time, it is very necessary to use a lens transmission meter to test.
3. Used in remote control industry
Now for the remote controls on TVs, air conditioners and sensor holes for smart home sensors and sweepers, infrared light with a wavelength of 940 nm is usually adopted. Because it is not easily interfered by sunlight and has a strong transmission capability and is used as a carrier to transmit information. Infrared remote control has the advantages of high sensitivity, low interference to other electrical appliances, good stability and low power consumption. To detect the transmittance of infrared remote control at 940nm, you can use Linshang lens transmission meter. In addition to the application of the above materials, the lens transmission meter has a wide range of applications in films, plastic materials, glass and other industries.
IV. How to detect 850,940nm IR transmittance?
The operation of Linshang lens transmission meter is very simple. Let's take LS108D as an example to show you how to use it and how to connect it to computer software:
1. Test procedure
(1) First plug the lens transmission meter LS108D into the power supply, press the power button, next turn on, the lens transmission meter will automatically calibrate, when the three data shows 100%, you can start the test.
(2) Align the position of the mobile phone cover to be tested with the test hole on the lens transmission meter. The corresponding test result will be displayed on the lens transmission meter. Align the test hole with the measured object. The operation is very simple and convenient.
2. Connect to computer software
First, open the installation software on the computer, select the installation location, after the installation is complete, connect the lens transmission meter to the computer with a USB cable.
Open the software and log in with the original password of 123456. After entering the display interface, when the display light is green, it means the connection is successful.
Click the parameter setting, you can set the upper and lower limits of different bands, according to the actual needs during production. In addition, the type of counting can also be set, trigger counting, computer mouse trigger counting and automatic counting can be set.
On the measurement interface, unloading indicates that the test can be started. Click Count to save the measured data. If the upper and lower limits are set and the measured material fails, the interface will show NG.
After the test is completed, the test data can also be exported to the EXCEL table.
3. Fast and slow measurement switching
The lens transmission meter LS108D can switch between fast and slow measurement modes. Slow measurement is suitable for manual alignment of the test hole. The rapid measurement is suitable for batch detection on the production line equipped with positioning devices. The rapid measurement mode can greatly improve the detection efficiency. The factory default of lens transmission meter LS108D is slow measurement mode. The switching method can refer to the following video:
Linshang lens transmission meter manufacturers not only provide excellent products, but also provide good after-sales service. The instruments all support one-year warranty and lifetime maintenance. It is the best choice for you to choose lens transmission meter.
