WebWavelength: 1064 nm. IR (infrared) light contains the most versatile wavelengths for laser processing. As the name implies, IR light contains the wavelengths longer than visible red (i.e. longer than 780 nm). Typical characteristics of 1064 nm wavelength range lasers Infrared radiation is generally considered to begin with wavelengths longer than visible by the human eye. However there is no hard wavelength limit to what is visible, as the eye's sensitivity decreases rapidly but smoothly, for wavelengths exceeding about 700 nm. See more Infrared (sometimes called infrared light and IR) is electromagnetic radiation (EMR) with wavelengths longer than those of visible light and shorter than radio waves. It is therefore invisible to the human eye. IR is generally … See more In general, objects emit infrared radiation across a spectrum of wavelengths, but sometimes only a limited region of the spectrum is of interest because sensors usually collect radiation only within a specific bandwidth.
