Let There Be LightTools 5.4

By DE Editors

The newest release of the illumination design and analysis software from Optical Research Associates (ORA; Pasadena, CA), LightTools 5.4 is said to have been enhanced with new capabilities for modeling surface textures and a number of improvements to its optimization engine.

LightTools Version 5.4 introduces a surface-texture feature that lets you create an arbitrary geometrical object and then produce surfaces in which the object is positioned repeatedly in a variable pattern. According to ORA, you can move rotate, and scale the texture objects within your pattern individually. Additionally, you can refine these parameters automatically refined using the LightTools Optimization Module, a modeling and optimization capability said to be particularly useful for designing critical components of LCD backlights, micro lens arrays, digital micromirror device (DMD) projection systems, and light pipe components.

ORA also cites two new merit functions in LightTools 5.4 that enhance the LightTools Optimization Module for many common illumination applications.  The first, the Focus Merit Function, is said to facilitate the optimization of optical system illuminance at a specified receiver location. The second, the Collimate Merit Function, makes it easier to maximize light intensity projected in a given direction.

Other improvements in LightTools 5.4 include new support for the CATIA V5 file format and refinements to the software’s optimization algorithms, which, the company says, can produce faster convergence results and increase your optimization solution success rate.
