  • Tracepro 5.0
May 2008
Lambda Research Corp.Request Info
LITTLETON, Mass., May 19, 2008 -- Lambda Research Corp.'s TracePro 5.0, the latest version of its software for optical modeling, design and analysis, features new capabilities including enhanced light source modeling, the company said.

TracePro 5.0 gives users the ability to combine multiple light sources with various wavelength spectrums in one TracePro model and analyze numerous light source interactions in the same ray trace. In addition, a user-defined, customized surface source database can be built using the software, Lambda Research said. For example, TracePro's new surface source property editor allows the user to specify light source behavior dependant on specific wavelength, temperature and emission angle.

Users can also now specify particular light source wavelengths to be traced for all source types (surface, grid and file sources) providing the designer with greater modeling flexibility. Fluorescence emission wavelengths can be now defined for each fluorescent object enabling more effective modeling and analyzing of fluorescent dyes with varying emission spectrums. These new features result in more efficient and flexible ray-trace LambdaColorMap.jpgruns, saving designers time and effort, the company said.

Also compatible with version 5.0 is a stand-alone light source property wizard that helps the user import light source properties such as wavelength spectrum and radiation patterns from manufacturer's data sheets. This wizard is downloadable from Lambda Research's Web site for TracePro customers current on their M&S subscriptions.

TracePro 5.0 users will also benefit from significant enhancements in the user interface for modeling light sources, improved flux report, reverse ray trace and luminance ray trace, the company said.

The emission of light or other electromagnetic radiation of longer wavelengths by a substance as a result of the absorption of some other radiation of shorter wavelengths, provided the emission continues only as long as the stimulus producing it is maintained. In other words, fluorescence is the luminescence that persists for less than about 10-8 s after excitation.
Luminous flux emitted from a surface per unit solid angle per unit of area, projected onto a plane normal to the direction of propagation. Also known as brightness and luminous sterance.
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
