Laser Scanner |
An optical bar code reading device using a low energy laser light beam as its source of illumination. |
LED |
LED ( Light Emitting Diode ) - A semiconductor that produces light at a wavelength determined by its chemical composition as a result of electrical simulation. A range of devices is available, each having a single output over a restricted band of light, to perate at points in the spectrum between 600 ( visible red ) and 900 ( infrared ) nanometres. It is commonly used as a light source in wand type bar code readers. |
light margin |
The EAN/UPC term equivalent to quiet zone.
See Quiet Zone |
light pen |
In Bar Code system a hand held scanning wand, which is used as a contact Bar Code reader held in the hand.
