ABSTRACT:
The optical performance of the LaJet Energy Corporation's membrane faceted concentrator, Model LEC-460, was evaluated at Sandia National Laboratories, Albuquerque, using a fluxmapper, a device that measures flux intensity in the aperture plane of the collector with a movable Kendall

radiometer. Three-dimensional flux intensity plots and flux contour maps were produced from the data, and numerical integration of the data was performed to obtain an estimate of the total integrated power into the aperture plane. The test results, normalized to a reference insolation value of 0.1 W/cm2, indicated a peak flux of 172 W/cm2 and a total integrated power of 30.2 kW. The net efficiency of the collector in a clean mirror condition was estimated to be 77.4%. Show Less
