Invisible IR LED 940nm 1050nm 1300nm

Guangmai Technology is proffesional in making the Invisible IR LED 940nm 1050nm 1300nm.

Obviously IR wavelength is invisible light. Why is 850nm visible in the outer infrared of IR LED but not visible at 940nm?

Infrared sensor cameras usually automatically switch to night infrared photography mode when working at night. Just as it is not easy for human eyes to see things at night, infrared photography mode also needs infrared night vision lights to strengthen the light, so as to take clearer nights. photo.

The light visible to the naked eye is called visible light, and the wavelength of visible light is 380~760nm. The order of the wavelengths of visible light from short to long is: purple light, blue light, cyan light, green light, yellow light, orange light, and red light. Light with a longer wavelength than red light is called infrared light or infrared (infrared). Infrared light cannot be seen with the naked eye.

The same is the LED infrared night vision light that emits infrared light, but why is it that the LED infrared night vision light with a wavelength of 850nm is visible?

One thing to be clarified here is that generally we say that the infrared lamp is 850nm, not that it only emits light with a wavelength of 850nm. In fact, the light it emits has a wavelength range, and 850nm is the peak light intensity in this range. The farther away from this peak, the lower the light intensity.

The light intensity of the 850nm LED infrared night vision lamp in the visible part (less than 760nm) still has not reached 0, that is to say, it still emits weak visible light, and the human eye can still feel the faint light.

The light emitted by the 940nm LED infrared night vision lamp has a light intensity of 940nm, which is farther from the visible light. When the light intensity reaches 0, the minimum wavelength is higher than the visible long wavelength of 760nm. Therefore, the 940nm LED lamp emits The light is not visible to the naked eye.
