An Overview of LightTools 6.1
LightTools 6.1 began shipping to last month. If you have not already received your update, it should arrive soon. Here is a summary of some of the enhancements included in LightTools 6.1:
- A new Ray Path feature can be used as a diagnostic tool for identifying, visualizing, filtering and analyzing ray paths in your model. This new feature is useful for designing systems with multiple contributing paths as well as for stray and scattered light analysis.
- Enhancements to the LightTools Optimization Module include the incorporation of the Backlight Pattern Optimization (BPO) feature on the Optimization Menu. In addition, several customer requested enhancements have been made to the BPO and the Parameter Sensitivity features.
- LightTools' user interface includes an enhanced illumination simulation progress dialog box that includes additional information such as the current ray number being traced, elapsed time, and time remaining in a simulation.
- Measured BSDF scatter data can more easily be included in your model, with an initial sample library of 15 measured materials available for download from ORA's Customer Service web site, www.oraservice.com. We will continue to increase this measured sample library.
- The LightTools utility library includes a new Solar Tracking utility for analyzing solar collectors, a new Compound Concentrator modeling utility, and enhanced Help.
- Phosphor Modeling, now available in the Advanced Physics Module, includes the following enhancements:
- The Phosphor Mean Free Path can now be defined as constant with wavelength, as wavelength dependent, or as based on MIE theory.
- Users can now define excitation data for phosphor using an Excitation Spectrum definition or via a Quantum Yield (quantum efficiency) model.
- Options for specifying unconverted rays has been expanded to include isotropic, undeviated, based on MIE theory, as well as a user-defined model.
- A new probabilistic ray splitting option has been added for phosphor material for more efficient ray tracing.
- A new probability model for determining the probability of rays hitting inert particles in a phosphor material.
- A new Gradient Index (GRIN) modeling capability has been added to the Advanced Physics Module. This new capability supports the modeling GRIN material using either NSG SELFOC glass via a built-in catalog, or as user-defined gradient index definitions. The user-defined GRIN capability allows you to define GRIN equations using the LightTools application programming interface for defining materials that cannot be modeled using the standard SELFOC equation.
A recorded demonstration of these and other enhancements included in LightTools 6.1 is available for viewing on ORA's Customer Service web site, www.oraservice.com, under .
LightTools 6.1 Service Release: A downloadable Service Release patch, to address a bug affecting Gaussian scattering, is currently available at
http://www.opticalres.com/ltdownloads_f.html
We strongly encourage you to download and apply this patch after installing version 6.1.
