Sciencetech's line of large area highly collimated flash solar simulators are capable of illuminating targets of 1.8 x 1.5m with uniform solar illumination. Our flash system is manufactured to achieve Class AAA by ASTM standards for targets within that area (IEC and JIS are available upon request). This makes our system one of the largest, most uniform solar simulators currently available on the market. Our highly collimated flash solar simulators illuminate targets with a collimation angle of +-0.5 degrees. This makes them ideal tools for studying concentrating photovoltaics and concentrating solar thermal devices.
