Abstract

Mercury-containing fluorescent lamps are commonly used in reproduction devices wherein an original document is incrementally illuminated in a scanning mode by one or two mercury fluorescent lamps. These lamps are subject to various problems such as instabilities in the axial optical profile and long warm-up time. A fluorescent lamp in which the mercury is replaced by one of the rare gases such as neon avoids these problems. Such a lamp would be inherently more stable, particularly to temperature variations and would have instant-on characteristics. Some examples of rare gas fluorescent lamps are as follows:
