What does NM mean in color?
What does NM mean in color?
The human eye sees color over wavelengths ranging roughly from 400 nanometers (violet) to 700 nanometers (red). Light from 400–700 nanometers (nm) is called visible light, or the visible spectrum because humans can see it.
What Colour is 810nm light?
RED
LOWER INFRA-RED: 850nm – 810nm – Nearly invisible, a very dull red glow can sometimes be observed when viewed directly.
What nanometer is purple?
around 400 nanometers
The wavelength of violet light is around 400 nanometers (or 4,000 Å). Ultraviolet radiation oscillates at rates between about 800 terahertz (THz or 1012 hertz) and 30,000 THz. When we talk about visible light, we refer to the different wavelengths of light across the visible spectrum by the names of colors.

Is 750 nm visible?
The visible spectrum is the portion of the electromagnetic spectrum that is visible to the human eye. A typical human eye will respond to wavelengths from about 380 to about 750 nanometers. In terms of frequency, this corresponds to a band in the vicinity of 400–790 terahertz.
