940nm infrared LEDs are totally invisible to the naked eye, which means you can't see whether the 940nm working or not. Unless you watch it through some device(like phone's camera), which will show some purple or white color light.
Under the same power, radiation intensity of 850nm will be higher than the 940nm. Of course, 940nm also has its own unique advantages. It is the naked eye that is indistinguishable from work or from work, therefore, its application has been widely used in many special markets in the modern era.
We supply the 3528 940nm SMD IR LED and 3528 850nm SMD IR LED products with difference power, such as: 0.1W 940nm, 0.2w 940nm, 0.3w 940nm, 0.4w 940nm, 0.5W 940nm, 0.6w 940nm, 0.8W 940nm, 0.1W 850nm, 0.2w 850nm, 0.3w 850nm, 0.4w 850nm, 0.5W 850nm, 0.6w 850nm, 0.8W 850nm and so on.
