Definitions for "HELIUM NEON LASER"
A type of laser commonly used in bar code scanners. It emits coherent red light at a wavelength of 633 nm.
The type of laser used most often in bar code scanners.
The most commonly used gas laser. The HeNe laser has an emission that is determined by neon atoms by virtue of a resonant transfer of excitation of helium. It operates continuously in the red, infrared and far-infrared regions and emits highly monochromatic radiation. Learn more about Helium Neon Laser...
