783-2046-1 Ozone Producing Double Bore Lamp

The name “double-bore” comes from the special quartz used to make the Ultraviolet lamps. This glass consists of quartz tubing with a quartz partition, or septum, through the center (see drawing below). This allows the plasma to ignite at one electrode and travel around the septum back down to meet the other electrode creating an arc of U.V. energy. These bulbs are low pressure, cold cathode, mercury vapor lamps which are manufactured from either fused quartz (ozone-producing) or ozone-free quartz. (ozone-free quartz lamps can replace an ozone-free sleeve for most applications). The specialized design of this mercury bulb eliminates dangling lead wires because of their location at only one end of the lamp. This feature is ideal for such applications as submerging the lamp into a liquid or inserting the lamp into small apertures. The double-bore has strong isolated spectral lines that are well separated from the others and the bulbs are free from contaminates which are harmful to the operation of the lamp. Jelight Company takes extra, unique steps in the manufacturing process to ensure that each lamp is free of contamination. These processes improve the quality, stability, uniformity, and lifetime of the lamps. When operated properly, the lamp is extremely stable which is important for accurate calibration and instrumentation applications where this stability is vital. In comparison to other UV light sources, the double-bore lamps are very cool burning; the temperature rarely exceeds 100° C. This is important in processes where the components or substances must not be heated by the light source used.
