OBB KiloArc™ The Brightest 1000 Watt Xe, or Hg/Xe, Illuminator in the Industry
 The KiloArc™ illuminator includes: One compact integrated housing that includes the lamp housing, power supply, igniter and quick switch lamp replacement; just select the desired lamp, either the 1,000 watt xenon or 1,000 watt HgXe.
Please note that the OBB KiloArc™ illuminator is designed for 1,000 watt lamps only. If you are interested in smaller arc lamp systems 75 watts to 150 watts, please also refer to our PowerArc™ light source for our compact arc lamp systems.
Lamp Housing
You would have to buy 6 old style vertical lamp housings to deliver the same number of photons that a KiloArc™ delivers to a single point!
At the heart of every OBB KiloArc™ is a proprietary on-axis ellipsoidal reflector. Our reflectors collect up to 70% of the radiant energy from the arc lamp, versus 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 from a conventional system.
The arc source is located at one focus points of the ellipse, and the radiation is reflected by the ellipse to the secondary focus which is actually outside of the KiloArc™. 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 Lamp housing can deliver up to 11 times more optical power into a given smaller area than a conventional lamp housing.
Our ellipsoidal reflectors are proprietary in design and the coating used. They are NOT electro-formed reflectors, which can distort with heat, and can degrade within months. Our proprietary design ensures that distortion of the critical ellipsoid cannot occur as the lamp reaches its operating temperature. This ensures thermal stability of focus. The coating ensures reasonably long operating life, typically 2–3 years.
The KiloArc™ ellipsoidal reflector is an f/4 reflector. The f/# is important when considering matching the KiloArc™ source to some other components like, fiber optics, liquid light guides or monochromators. However f/# for an ellipsoidal reflector is not an indicator of light collection as it is in a simple lens design. The shape and size of the ellipsoidal reflector determines how much light is collected from the lamp arc. The f/# only determines the focal cone angle.
The KiloArc™ is air cooled. However since the system uses ozone free lamps, there is no ozone or venting requirements, although there is an exhaust hose adapter if you want to vent the warm air out of a lab.
The OBB KiloArc™ is a sealed arc lamp housing with a quartz window through which the focused light is delivered. Below is the spectral transmission curve for the quartz window.

Unique Quick Release Self Aligning Lamp Replacement.
You have a choice of two lamps depending on the spectral output that you require; xenon or mercury-xenon. The lamps are provided as a complete pre-aligned assembly which includes a cooling fin and a quick release self aligning connector. Of course you may order both types of lamps as they are interchangeable.
The xenon gas used in the lamp provides continuous spectra from 180 nm to 2,500 nm at varying intensities (refer to spectral output graph). The mercury-xenon provides more of a line spectra (refer to spectral output graph). The spectral curves for xenon and mercury-xenon are normalized (relative intensities) therefore, although you cannot tell from the curves, the mercury-xenon lamp actually has greater intensities than the xenon lamp at it’s various peaks. Refer to specifications web page for detailed spectral characteristics of these two lamps.
The KiloArc™ uses ozone free quartz lamps which cut off the deep UV below 240 nm.
Typical lamp lifetime is 1,500 hrs. The lamp lifetime is highly dependent on operating conditions. Lamps should not be operated above their rated wattage (1,000 W).

Power Supply
The KiloArc™ illuminator has a dedicated 1,000 watt power supply and igniter built into it. The power supply is a high efficiency switch-mode type supply. It is rated at 1,200 watts to ensure that it is not operated at the limit of its range. This provides better stability and longer lifetime when operated at 1,000 W. The KiloArc™ has triple shielding and electronic filtering to ensure that there is no RF transmitted or radiated out of the illuminator to interfere with sensitive equipment, like computers.
Igniter
The internal igniter provides a 45 KV pulse for reliable lamp ignition. Ignition noise can disrupt, or even destroy, sensitive equipment in the vicinity of an arc lamp during start-up. This can be quite a concern in a crowded lab environment. OBB Engineers carefully designed and tested the KiloArc’s triple shielding housing and electronic filtering to ensure that there is no RF transmitted or radiated out of the illuminator

Smart Features
There are two LED indicators on the back, one called the “STATUS” which shows the modes of operation: cool down, stand by, or error. The other is an ERROR indication. It senses problems and displays error codes when they occur.
Particular considerations were paid to safety. The lamp chamber and power supply are constantly monitored for heat, as well as the airflow for cooling. If there are problems the lamp will shut down automatically and you will receive an appropriate error message. If the access door to the lamp is loose or open the lamp will turn off, or not ignite..
We tried to make the operation as fool proof, safe and reliable as possible, making the KiloArc™ ideal for commercial applications.
Mounting Information
In case you wanted to mount the KiloArc™ the following are the mounting options on the base plate of the supply:
Set of Feet
The KiloArc™ comes without feet on a level plate. In case you want to operate it on a surface that requires leveling, we can provide you with a set of four adjustable feet.
4-Inch Exhaust Hose Adaptor
The KiloArc™ does not generate harmful levels of ozone (less than a typical copier). It does generate some heat. Therefore venting is not a requirement, but if you do desire to vent the exhaust from the KiloArc™, select this option.
