With our extensive knowledge of the medical markets, combined with proven expertise in LED technology, OSRAM is able to create unique solutions of the highest value.
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.
Xenon discharge lamps were first developed by OSRAM over fifty years ago. Today, OSRAM XBO® xenon short arc lamps are used "> extensively in the medical and scientific communities for microscopy, endoscopy and other minimally invasive surgical procedures. In XBO lamps, a luminous arc occurs between two electrodes in an atmosphere of pure xenon gas.
Because the gap between the electrodes is only a few millimeters, XBO lamps can be used as ideal point sources. The lamps feature extremely high light output and a color temperature of approximately 6000K—similar to that of daylight. OSRAM XBO lamps provide a continuous spectrum in the visible range and have a near perfect color rendering index of greater than 95. Other features include constant color properties throughout lamp life, high arc stability, hot restart capability, virtually full light output immediately after ignition, and DC operation. For light guide applications, some lamps feature ellipsoidal dichroic reflectors to provide maximum output.
Reflectorized OSRAM HTI™ lamps are an excellent light source for endoscopy and other medical fiber-optic applications. In these AC-operated discharge lamps, an arc is formed in a dense vapor atmosphere consisting of mercury and rare earth halides.
With short arc technology for greater optical control, HTI lamps offer high lumen output, daylight color characteristics, and excellent efficacy in a compact package. OSRAM engineers have developed special reflector designs that optimize color homogeneity when used in light-guide applications.
OSRAM offers tungsten halogen lamps for a wide variety of medical and scientific applications including overhead surgical and fiber-optic illumination, microscopy, endoscopy and UV-curing.
Lamps are available in a range of voltages and wattages with numerous reflector and base configurations. The performance advantage of halogen technology comes from the fact that any tungsten atoms vaporized from the filament are able to combine with the halogen atoms in the fill gas and redeposit on the filament.
In addition to helping prevent black carbon deposits from forming on the bulb wall, this process increases luminous efficacy, lumen maintenance and lamp life.
Look for the letters HLX in the ordering codes of OSRAM tungsten halogen lamps. The HLX identifies lamps that employ
XENOPHOT™ technology, an innovation first introduced by OSRAM. In XENOPHOT lamps, krypton—the normal fill gas used in halogen lamps—is replaced with xenon gas. The xenon reduces the rate of tungsten vaporization and allows for a higher filament temperature. Depending on the application, XENOPHOT can either improve luminous efficacy or can extend the lamp’s service life.
