LITTLETON, Mass., Nov. 7, 2012 — TracePro 7.3 is the latest release of Lambda Research Corp.’s illumination and optical analysis software. It features a fully automated interactive solar analysis utility and the addition of two geometric modelers. The solar function enables users to analyze solar collector systems by defining the geographical location, period of sun travel and solar power emission to simulate cloudy to clear day calculations. Complete diagnostic output is available, including irradiance and candela maps on target surfaces, total flux on the target per time period, and tabular output detailing efficiency over time. This new utility reduces analysis time by automating the solar analysis process through easy-to-use dialogs to set up sun position using Google Earth for location verification, trajectory verification using 3-D Earth modeling and user output analysis qualification via dialogs. The 7.3 release also features two new RepTile feature types, floating blocks and chiseled logs. These two features are suitable for simulating media in paints and simulating new backlight scattering particles for displays. The two new geometry modeler utilities include a quick 2-D sketch function with interactive ray-tracing for geometry verification and a full 3-D modeler to create nonsymmetric free-form optics using both conic and spline surfaces.
