LightTools 5.2

Illumination Design and Analysis Software
PASADENA, Calif., Dec. 2 -- Optical Research Associates (ORA) has introduced LightTools version 5.2, which it said is the first illumination design and analysis software to deliver a fully integrated system optimization tool.

ORA said the new LightTools optimization module improves the performance of virtually any type of illumination system and allows designers to choose from hundreds of system parameters to designate as variables in order to achieve specified luminance, illuminance or output intensity distribution goals.

Full integration of this optimization capability with LightTools 3-D solid modeling ensures that the optimizer delivers practical, realistic solutions that yield the best possible system performance in a fraction of the time it would take to accomplish manually.

Augmenting the capabilities of the LightTools optimizer is the parametric controls feature also available in LightTools 5.2. Used in conjunction with the optimizer or in earlier stages of system design, this new feature improves parameter management efficiency; by enabling the properties of various system elements to be associated, parametric controls permit global changes on a model to be accomplished by varying a single parameter.

LightTools Version 5.2 also introduces several powerful features that specifically benefit flat-panel display designers. These include a library of models for commercially available display enhancement films (DEFs) and brightness-enhancing films (BEFs), which are widely used in the construction of LCDs. In addition, LightTools now supports modeling luminescent materials, such as phosphors, which are commonly found in white LEDs, fluorescent lamps, backlight displays and CRTs. This new release also contains 90 prebuilt "starting point" designs for automotive, backlight, digital projector, imaging, LED, light pipe, general lighting and stray light applications.

With more than forty years of success as an industry leader, ORA is committed to delivering innovative solutions to the optics industry. With its CODE V and LightTools software products, ORA is the world's leading developer of optical software. ORA is also the largest independent supplier of optical design and engineering services, with more than 4000 completed projects since the company was founded in 1963.
