LightTools 6.2

LightTools 6.2, the premier illumination design and analysis software
it has been given a backward ray-tracing capability, which can greatly reduce the time needed to design and analyze systems such as sources, luminaires, and projectors. The approach saves time by tracing many fewer rays than a forward ray trace would require to reach the same level of accuracy. The capability allows the designer to analyze illuminance, intensity, and color at a particular location, or in a particular direction, rather than taking unnecessary time to analyze the entire pattern.
The introduction of a backward ray-tracing capability can reduce the time needed to design and analyze systems such as sources, luminaires, and projectors. This provides a solution for analyzing illuminance, intensity, and color at a particular location, or in a particular direction, rather than taking unnecessary time to analyze the entire pattern. It saves time by tracing far fewer rays than a forward ray trace would require to reach the same level of accuracy. In addition, the new LightTools SolidWorks Link Module can reduce design cycle time by enabling users to build 3D models in SolidWorks and import them into LightTools, where they can assign optical properties, optimize the design, and update the SolidWorks model. This capability provides full interoperability, so changes made in one program are updated in the other.

LightTools 6.2 also improves modeling of white light LEDs, now widely used in lighting and displays, with the added ability to specify materials with multiple phosphor particles, along with their size and density distributions.
