LightTools 6.1
May 2008

PASADENA, Calif., May 7, 2008 -- Optical Research Associates (ORA) said the latest version of its LightTools illumination design and analysis software, LightTools 6.1, delivers a number of advanced modeling and analysis features that facilitate the design of sophisticated luminaires, LEDs, and displays.

For example, LightTools 6.1 includes a new "ray path" feature that makes it easy to identify exactly what system elements are contributing to light loss, scatter, unintentional reflections, or ghost images. This is particularly useful in the design of stray-light sensitive systems, such as microlithography steppers or astronomical instruments, the company said. LightTools also now supports accurate modeling of scattering surfaces by allowing users to apply measured BSDF (bidirectional scatter distribution function) data, both isotropic and anisotropic, to a surface.

Support for gradient index (GRIN) lenses has also been added, including radial, axial, spherical, and user-defined gradients.

Accurate modeling of LEDs with LightTools has been further extended with new ways to specify the properties of phosphors, ORA said. In particular, the mean free path (the average distance that a ray will travel in a material before striking a phosphor particle) can now be described as a constant, as a wavelength-dependent quantity, or by using Mie-scattering theory.

LightTools has also been enhanced with expanded foreign language support; in addition to the long-available Japanese, program menus and dialog boxes are now available in French, German, simplified Chinese, traditional Chinese, and Korean.
