Consisting of a unique arc lamp housing tightly coupled to a 0.2 meter monochromator, the Tunable PowerArc™ Illuminator is a self aligned illuminator that generates milliwatts of intensity and offers the versatility of continuous wavelength and bandwidth selection. The wavelength can be set manually or, for ultimate flexibility, it can be scanned under computer control. The Tunable PowerArc™ Illuminator could not be easier to operate. The system requires no ozone venting, and with the 75 watt xenon lamp no cooling is required. Simply push the start button and dial the wavelength and bandpass of output that you require.

At the heart of the OBB PowerArc™ lamp housing is a proprietary on-axis ellipsoidal reflector. Our reflectors collect up to 70% of the radiant energy from the arc lamp, as compared with only 12% for typical condenser systems in vertical lamp housings. The ellipse literally wraps around the arc lamp, collecting 5 to 6 times more output power than a conventional system.

The arc source is located at one focal point of the ellipse, and the radiation is reflected by the ellipse to the secondary focus which is actually outside of the lamp housing. Since the light is brought to a focus by reflection rather than refraction (through a lens), there are less losses from absorption or lens-surface back-reflection. This design is so efficient that an OBB PowerArc™ lamp housing can deliver  up to 11 times more optical power into a given smaller area than a conventional lamp housing. This is critical when illuminating light guides, monochromator slits, pinholes or other small areas.
