New Modeling, Optimization Features
PASADENA, Calif., July 2, 2007 -- Expanded system modeling tools and optimization capabilities are among the features of the latest release of LightTools illumination design and analysis software, said its developer, Optical Research Associates (ORA).

LightTools 6.0 includes a user-defined optical properties feature that the company said provides tremendous flexibility in creating specialty optical components, allowing modeling of application-specific, proprietary elements such as specialty polarization components, grating components (with efficiency calculations), scattering surfaces (including anamorphic scatterers) and coating definitions. The new version also allows modeled elements, for example the embedded phosphor and epoxy covering in an encapsulated LED, to be immersed in one another on multiple levels.

ORA-LightTools-6.jpg"The LightTools optimization module, available in beta form in previous LightTools releases, has already proven to be a widely applicable feature that can automatically find optimal illumination design solutions, saving the designer days or even weeks of effort that might be needed to manually explore the design space," ORA said. "LightTools 6.0 brings the first formal release of the optimizer and expands it in several important ways. In particular, it now permits optimization of a given illumination distribution (e.g., uniform or Gaussian) while simultaneously maximizing optical power."

LightTools also adds functionality for evaluating how sensitive a system is to variations in specific parameters, which can be useful for selecting variables before beginning optimization, and even enables some basic tolerance analysis computations, ORA said.
