HBO Mercury Short Arc

OSRAM HBO® mercury short arc lamps are widely used in the medical and scientific fields for fluorescent microscopy and industrial UV-curing. In an OSRAM HBO lamp, a luminous arc is generated in a high pressure atmosphere of mercury vapor.


Because the arc is only a few millimeters in length, HBO lamps are an almost perfect point source of light. These lamps offer high radiant power in both the UV and visible range, high optical quality and long life.  Reflectorized lamps have been specifically designed to provide exceptional efficiency in light guide applications. OSRAM HBO lamps for medical and scientific applications are available from 50 to 500 watts.
