Product Feature And Application
The 850nm infrared LED can see red light because the spectral range of the human eye is within the visible light range, and the spectrum emitted by the 850nm infrared LED also contains a certain red light component. In addition, the LED light sources of red light and infrared light are also widely used in physiotherapy instruments and other fields. It should be noted that when using the 850nm emission tube, we should pay attention to anti-static, and the soldering iron should not exceed 30W, the time should not exceed three seconds, the temperature of immersion welding should not exceed 260 degrees, and the time should not exceed three seconds. In addition, the wavelength of 850nm infrared ray is often used in security, infrared night vision monitoring, infrared camera, infrared light supplement and other aspects.

FAQ
1.What products can 2835 SMD LED 850NM lamp beads be used on?
850nm infrared lamp bead is suitable for remote signal transmission, lighting and security monitoring and other fields, as well as digital shooting, monitors, apartment walkie talkie, anti-theft alarm, infrared waterproof and other products.
2.850NM lamp bead brand recommendation?
There are many common 850nm infrared LED lamp bead brands on the market, and each brand's 850nm lamp bead has different characteristics and application scenarios, and the choice of which brand's product needs to be comprehensively considered according to actual needs.
3.What is the difference between infrared 850 NM and 940 NM?
The IR 850nm and 940nm are both wavelengths of the infrared LED, but there are some differences between them. First, in terms of transmit power, 850nm is the largest, while 940nm is the weakest. Secondly, at the receiving end, the generally better receiving head is to filter the optical interference with the wavelength below 850nm, and the 850nm transmitting tube emits more power, but at the edge of the receiving head filter band, so 80% of the receiving head has been filtered off, so that its receiving performance is worse than 940nm. In addition, 850nm-880nm is used to detect the speed of the engine, 900nm is mainly used as a test instrument to detect human blood gas, blood sugar, etc. 940nm is mainly used as a remote control for position locking. Therefore, when selecting infrared light sources, it is necessary to choose the appropriate wavelength according to the actual application scenarios.
4.2835 850nm infrared LED application?
2835 850nm infrared LED is widely used. The product line of Shenzhen Shouyou Technology Co., Ltd. includes infrared IRLED beads (850nm). In addition, infrared LED with a wavelength of 850nm is widely used in security monitoring, vehicle night vision, biosensing and other fields. At the same time, the customized LED light source can also customize the LED light sources of different wavelengths according to customer requirements, such as the special wavelength LED light source of 850nm. Therefore, the infrared LED of 2835 850nm 950nm can be used in security monitoring, vehicle night vision, biosensing and other fields.
