TracePro 5.0 is the latest version of Lambda Research’s optomechanical design software. Used in the design and analysis of LEDS, luminaries, and lighting systems, TracePro 5.0 now provides an all-new interface for modeling optical sources. The user is able to define and manage spectral data for each unique source and combine different source types in a single ray trace. These features offer time savings to any design process that involves multiple sources or source alternatives and fluorescence. New analysis capabilities include flux vs. optical path length or time of flight. New simulation advances include reverse ray traces and luminance ray traces with blackbody and gray body sources. The software update also features new add-in utilities that assist in quickly and accurately creating and optimizing properties.
