The 45UV5 scanners use a UV-eye detector. This detector is a sealed, gas-filled, UV-sensitive tube containing two electrodes connected to a source of AC voltage. When UV radiation of sufficient energy falls upon the electrodes, electrons are released and the inter-electrode gas becomes conductive, resulting in an electric current flow from one electrode to the other. The current flow starts and ends abruptly and is known as an “avalanche.”
