The OBB KiloArc™ is The Brightest 1000 Watt Xe, or Hg/Xe arc lamp, Illuminator in the Industry


KiloArcIf you need a broadband light source in the UV/Vis/NIR portion of the spectrum, an arc lamp has no peer. And if you are looking for the most intense broadband light source you can get, then the KiloArc™ has no peer. The intensity of an arc lamp is extremely high and, depending on the lamp, reasonably continuous throughout the region from 240 to 1,200 nanometers. Usable intensities are even available in the deep UV down to 180 nm and in the near infrared out to 2,500 nm.


While arc lamps themselves are very similar from manufacturer to manufacturer, the arc lamp housings and power supplies that operate these lamps are very different from manufacturer to manufacturer. As such the arc lamp housing can have a dramatic affect on how an arc lamp illuminator performs. We believe that our long experience in light source design is what allows us to give you a unique light source that truly is a better illuminator.

You would have to buy 6 old style vertical arclamp housings to deliver the same number of photons that a KiloArc™ arc lamp illuminator delivers to a focused spot!

1 KiloArc equals 6 vertical lamps

OBB Arc Lamp Housing Design; A Better Approach

Users of old style vertical arc lamp housings are throwing away as much as 90% of the lamps output, due to poor collection efficiency. These old style vertical lamp housings have a collection lens in front of the arc lamp and sometimes, but not always, a back reflector behind them. The problem with this old design is that only the light that actually strikes these optical elements is delivered outside of the lamp housing. All other photons emitted by the lamp are wasted, simply heating the inside of the lamp housing. Conversely the unique OBB KiloArc™ lamp housing has an enveloping ellipsoidal reflector that collects virtually all of the light emitted by the lamp arc, delivering those photons to a secondary focal point outside of the lamp housing, and it does so without any lenses. 

KiloArc Lamp Orientation

For an equivalent wattage of bulb, the OBB KiloArc™ delivers 5 to 6 times more light emitted by the same bulb, to the secondary focus which is outside the lamp housing! Our design just simply collects a larger solid angle of light than does the old style. That means that an OBB KiloArc™ lamp housing with a 1,000 watt xenon lamp provides the equivalent optical power of a 6,000 watt xenon lamp in an old style vertical lamp housing. And it does so with much greater power density due to a smaller focal spot, and at a small fraction of the cost.
