The 81030 High Flux Beam Concentrator focuses the 2 x 2 inch (51 x 51 mm) output beam from our 1000 and 1600 W Solar Simulators down to a 0.6 inch (15 mm) diameter spot, increasing the energy density by 7X with a ±5% intensity uniformity.
The output of the 81030 is equivalent to the intensity of 30 -50 "suns" (with a 1 kW source). It is very useful for high flux applications such as accelerated photodegradation studies and materials testing. All air mass filters are usable with the 81030.

Construction
The Beam Concentrator consists of a multi-element fused silica lens mounted in a tube that attaches to the output assembly of the simulator. It extends 1 inch (25.4 mm) below the base of the Solar Simulator. The 81030 comes with a stand, which elevates the Solar Simulator 9 inches (229 mm). This allows 8 inches (203 mm) below the end of the Beam Concentrator for fixturing and sample orientation (See Fig. 2).
Safety Considerations
When you use the 81030 with our broadband simulators, you will produce a spot with intense UV, visible and infrared radiation. In addition to the UV hazards, you should be conscious of possible combustion hazards should you use flammable absorbing targets. When coupled with a Solar UV Simulator, the 81030 produces extremely high UV irradiance with greatly reduced VIS and IR content. Note: the 81030 causes severe burns even with extremely short exposures. A protective face shield, and protective clothing must be worn when working with high intensity ultraviolet radiation.
