Sciencetech is proud to offer our new line of Ultra-High Efficiency (UHE) Class AAA solar simulators. By utilizing a completely new design for the beam homogenizer, the UHE systems are featuring high efficiency and higher power densities on target than previously possible. The UHE-16 A can illuminate 152 mm x 152 mm target size, while the Model UHE-16 AA-0 (for Meeting A0 demands) will illuminate 127 mm x 127 mm.Working distance between 45 cm and 60 cm depending on the model. Please find more details at:http://www.sciencetech-inc.com/fileuploader/download/download/?d=1&file=custom%2Fupload%2FFile-1421445694.pdfSpectral Match, Non-Uniformity and temporal stability will match ASTM E-27-05, IEC 60904-9 and JIS-V-8923.The system comes standard with a universal AM filter (AM1.5G), power supply, lamp, and a stand for normal vertical alignment (the beam facing downwards). Custom stands should be discussed with our Application Scientists.
