Full Spectrum Solar Simulator |
The 91160 produces power equivalent to ~2 suns, while model 91159 produces ~ 1 sun. With optional air mass filters, you can simulate various solar conditions. Table 1 shows the typical output of the 91160, in the design-irradiated plane. |

UV Solar Simulator |
The 91260 is ideal for UV testing without the complicating effects of high levels of VIS and IR. The percentage of UV in the total output of our full spectrum model is less than 6%. The percentage of UV in the total output of the UV model is ~36%. We use a UVB/UVA dichroic mirror to shape the output of the 91260 Solar Simulator. This dichroic passes 280 to 400 nm and greatly reduces the VIS and IR output of the lamp. You can use bandpass filters, after the dichroic, to further isolate the portion of the UV in which you are working. In Table 2, we show the typical output power, in the design-irradiated plane, from the 91260 UV Solar Simulator. |

What Makes Up a Solar Simulator? |
The Illuminator Housing |
The housing is an aluminum enclosure that holds the arc lamp, arc lamp ignitor, optical integrator, collimating lens, light shutter and light shutter power supply. It is equipped with five safety interlocks to ensure operator and system safety. An integral fan cools the lamp and optics. |
150 W or 300 W Xenon Arc Lamp |
Both the Full Spectrum and the UV Simulators use an ozone free lamp, which has negligible output below 260 nm. For applications where DUV is necessary replace this lamp with the 6259 UV enhanced model. Please notify a Sales Engineer at the time of order, if you want the 6259 Lamp. |
The 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.
For long-term (>8 hours) stability-critical applications and/or for exposure control, we suggest you also order the 68951Digital Exposure Controller. |
UVB/UVA Dichroic Mirror (for 91260 UV Solar Simulator only) |
The 91260 UV Solar Simulator includes a dichroic mirror. It passes 280 to 400 nm and greatly reduces the VIS and IR. |
Electronic Shutter |
These simulators include an electronic splitblade shutter. The shutter is activated by a convenient push button switch on the illuminator housing, or via a contact closure or logic level input. You can also use the 68955 Hand-Held Shutter Switch. For automated exposure control, use the 68951 or 68945 Exposure Controller. |
Extended Care Program |
All Oriel® Solar Simulators are shipped with a one-year warranty on parts and labor. We now offer an extended care plan, which gives you coverage for two years. 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 considerable ultraviolet radiation. Exposure to intense UV radiation can cause delayed severe burns to the eyes and skin. Proper protective eyewear and glovesshould be worn at all times during operation. |
