USHIO Short Arc Mercury Lamps

HBO mercury lamps are short arc lamps in which the luminous arc burns in an atmosphere of mercury vapor at high pressure. Their main characteristics and benefits are:

· High radiance
· Multiline spectrum
· High radiant power in the UV and the visible range
· AC and/or DC operation

HBO mercury lamps are available in wattages ranging from 50 to 3400 watts. Lamps rated at less than 200 watts are predominantly used in scientific and technical applications such as:

· Fluorescence microscopy
· Fluorescence endoscopy
· Optical waveguide applications
· Schlieren photography
· Hologram projection
· UV curing

  Lamps rated at 350 watts and above are used almost exclusively for the fabrication of electronic chips in microlithography. Special applications for which lamps of any wattage can be used are laser simulation and effect light projection in the entertainment industry. We have compiled a list of a considerable number of different instruments. It will give you an overview of which lamp best suits which instrument.


Because of their high luminance, UV radiation and internal pressure in both the hot and cold state, HBO lamps may only be operated in enclosed lamp casings specially constructed for the purpose. Always use the protective jackets supplied when handling HBO lamps. When handling the lamps without their protective jackets, always wear safety goggles, a face mask and gauntlets with wrist protectors.

In case of a lamp burst, mercury will be emitted
