The term 850nm refers to the wavelength of light that measures approximately 850 nanometers (nm). A nanometer is a unit of length in the metric system equivalent to one billionth of a meter (1 nm = 10-9 meters). The specific wavelength of 850nm falls within the infrared (IR) spectrum of light, which is beyond the range of visible light detectable by the human eye.
