TracePro 6.0 is the newest version of Lambda Research Corp.’s optomechanical design software. It is x64-capable, enabling it to simulate larger systems using larger ray traces over spectral bands to investigate uniformity, solar and color issues with higher fidelity. It is recommended for Windows x64, Vista and System 7 operating systems. New analysis capabilities include an interactive CIE plot showing color gamut, enhanced RepTile prism geometry and solid concentrator constructors designed for simulating solid compound parabolic concentrators for solar applications. The property dialog boxes have been redesigned in a quick entry style and are alphabetical and simpler.
