Synopsys Inc. has enhanced its LightTools illumination design and analysis software, resulting from its acquisition of Optical Research Associates. LightTools 7.2 offers features that will help users graphically analyze simulation results, compute metrics and improve the efficiency of luminaire and solar products. These capabilities enable lighting designers to explore alternatives, study light behavior and improve product quality early in the process. The LightTools LumViewer, an interactive charting capability, has a new look and additional features to customize illumination simulation results to meet personal, company or industry standards. Computer-aided design (CAD) file elements enable iterative, seamless design with CAD software, and native compound parabolic concentrator objects improve the efficiency of luminaire and solar concentrator designs.
