Lambda Research and IB/E Optics Announce the Release of OptiBelPro™, a non-linear optimization module for TracePro^®

Littleton, Massachusetts, July 21, 2006 – Lambda Research Corporation, developer of optical software TracePro^® , TracePro Bridge™ for SolidWorks^® and OSLO^® , announces the release of OptiBelPro, a non-linear optimization module for its illumination design software, TracePro.

Optimizing an illumination system requires a way to automatically vary model parameters to achieve specific illumination distributions and the OptiBelPro module enables such an optimization process in TracePro. The module, developed by IB/E Optics, Hutthurm, Germany, is based on TracePro’s powerful macro language, Scheme, and offers users the flexibility to modify analysis functions and define custom merit functions to create user-defined irradiation distributions for illumination designs in TracePro. The main goal in the development of the module was to maintain optimization versatility since the design of illumination systems can be based on a wide range of diverse requirements.

Typically, the most important illumination design requirements are maximizing intensity and/or uniformity of light distribution. Below is an example model of a condenser system, which has been analyzed and optimized in TracePro utilizing OptiBelPro. We can compare the performance of the system when (a) optimized on light intensity only, and (b) when optimized on both light intensity and uniformity. The latter approach yields maximized uniformity of light distribution with a slight loss in light intensity.

OptiBelPro, the non-linear optimization module, assists TracePro users in improving their designs while increasing efficiency in ray tracing analysis and productivity in illumination system design. This new optimization module enables optics designers to create complex and performance enhanced illumination systems in a fraction of the time.
