Full Spectrum Solar Simulators |
Simulate hours of solar radiation in minutes with our 450 - 1000 W Solar Simulators. We offer models with uniform, collimated output beams in sizes from 2x2 to 8x8 inches, and a diverging beam model, which produces a diverging output beam up to 12 x 12 inches.
We offer two families of simulators. The Full Spectrum models, when used with air mass and/or bandpass filters, simulate a variety of solar spectra. The UV Solar Simulators closely match the UV portion of the solar spectrum, with little VIS and IR.
Fig. 1 shows the spectral output of these simulators compared to the UV models. When used with our easily interchangeable air mass filters, these sources simulate a variety of solar spectra. Tables 1 and 2 show the typical output of these simulators, in the design-irradiated plane. In addition to the collimated beam sizes offered, we also have a Full Spectrum Solar Simulator with diverging beam. This source, model 91190, produces a diverging output beam up to 12 x 12 inches. Table 3 shows the size of the output beam, at specific work plane distances. In place of the collimating lens, the 91190 Simulator has a window. |

UV Solar Simulators |
If you need a very high intensity UV source that closely matches the ultraviolet portion of the solar spectrum, with little VIS and IR, you want to consider our kW UV Solar Simulators. These sources use a dichroic mirror, which reflects 280 to 400 nm and minimizes the VIS to IR. Table 4 shows the typical output (W m-2) of the 91291, 2x2 Inch UV Solar Simulator. |

What Makes Up a Solar Simulator? |
The Illuminator Housing |
The illuminator housing holds the arc lamp, arc lamp ignitor, optical integrator, collimating optics, light shutter, and light shutter power supply. It is equipped with a safety interlock and a thermal interlock system to ensure operator and system safety. An integral fan and filter blower provides forced air-cooling to ensure optimal lamp, optics and housing temperature. |
450 W or 1000 W Xenon Arc Lamp |
Both families of the Solar Simulators use an ozone free lamp, which has negligible output below 260 nm. If you need the deep UV wavelengths, choose the 6269 UV Enhanced Lamp. Notify us at the time of purchase, if youd like to substitute the 6269 Lamp for the 6271Ozone Free Model. |
Power Supply |
The highly regulated power supply provides constant electrical power to the xenon lamp. A convenient preview feature enables you to set the lamp power prior to ignition. This reduces set up time, since there is no need to wait through the lamp's warm-up period to establish the operating power. |
UVB/UVA Dichroic Mirror (For UV Solar Simulators Only) |
For the UV Solar Simulators we replace the aluminized mirror with a dichroic, which passes 280 to 400 nm and greatly reduces the VIS and IR. You can use UV blocking filters after the dichroic, such as the 81017 Atmospheric Attenuation Filter, which simulates the UV edge of the sun. |
Manual or Automated Exposure Control |
Our Solar Simulators include an electronic splitblade shutter. You can externally control this shutter from the Digital Control Panel on the illuminator housing, or via a hand held switch, contact closure, or logic level input. For automated exposure control, order the 68945 Digital Timer. |
Extended Care Plan |
Extend the standard one-year warranty on these Solar Simulators by an additional year, with our Extended Care Program. Please ask a Sales Engineer about this plan when placing your order. |
Certification |
These systems meet Class B IEC 904-9 requirements, but do not come certified. |
Safety Considerations |
These illuminators produce very high intensity ultraviolet radiation. Exposure to intense UV radiation, even for very short periods of time, can cause severe burns to the eyes and skin. A face shield, gloves and protectiveclothing must be worn at all times during operation. |
