Fully Reflective Solar Simulators

Sciencetech manufactures three high power versions of Class BBA Fully Reflective Solar Simulators, and one low power (150 W) model. Sciencetech's properietary fully reflective design uses metal coated mirrors and passes the whole spectrum, no compromise. This is a distinct advantage over refractive based systems that are limited by the properties of the transparent material used. The fully reflective design utilizes a series of mirrors, including a special folding mirror that bends the light source without the drawbacks of refractive optics. This allows the simulator to direct the light beam from the arc lamp source to the target plane, producing a higher intensity, uniform illumination at the target plane than a competitor’s simulators. In Sciencetech’s line of fully reflective solar simulators the power output will typically be 1.3 times more powerful when compared to simulators that use the same wattage of arc lamp with diffusers to make the light field uniform at the target. The high pressure xenon lamp used in each simulator projects an excellent basic match for solar simulation. The solar spectral distribution at different Earth conditions can be simulated through use of Air Mass filters. For more variation of where your test surface is located, several simulators can be mounted on a vertical stand, and if coupled with a beam turning accessory, enable the simulator’s ability to project towards a floor, wall, or ceiling, depending on your research requirements. The air mass filters used with each simulator are 3" x 3" in size and can be easily switched in each model via a built-in access panel. There are two AM filter slots in each simulator; additional slots can be added upon consultation.

 Configuration

Sciencetech's fully reflective solar simulators can be configured to suit your requirements. The homogenizer can be customized to include a computer controllable shutter or a variable focus option that lets you position the uniform plane at different working distances from the output of the simulator. Numerous filtering options are available. Some filter options are added to the beam line through the built in filter drawer. Other filtering options require the addition of a beam turning filter holder. A range of solar cell chucks with options such as vacuum clamps, thermoelectric or water cooling, micropositioners as well as complete IV testing software and hardware are also available. The SS0.5k through SS1.6k models can be mounted on a vertical stand for downward facing operation. Note that the SS2.5k model must be mounted on a table for downward facing operation.
