This month, Synopsys' Optical Solutions Group held LightTools User Group Meetings featuring presentation topics ranging from LightTools case studies and usage tips to what's new in the software.

If you weren't able to attend the live meetings, there are still two live webinars you can attend on Thursday, September 27th and Thursday, October 4th. See below for free registration and topic details. 

Additionally, we've uploaded the presentations to the Customer Support Portal for viewing at your convenience. When you log in, you'll find the following presentations:

• LightTools 8.6 New Features
  LightTools 8.6 introduces several powerful new features including the Tolerance Manager, Automatic Optical Contact Detection, and backward simulation support for ray data sources. Improvements to the Freeform Designer, Configuration Manager, and quick access to properties of variables, tolerances, and aliases enhance existing LightTools capabilities.
  
  
• Using Backlight Pattern Optimization for Panel Luminaire Design
  Panel luminaires are becoming very popular in the lighting industry. This presentation covers a case study that uses LightTools’ Backlight Pattern Optimization (BPO) tool design a panel luminaire for uniform illuminance.
  
  
• Augmented Reality Design with CODE V and LightTools: A Case Study
  This presentation covers a case study of a see-through augmented reality system. A summary of the imaging lens design using CODE V is discussed before detailing the setup in LightTools for further illumination analysis.
  
  
• Complexity Trade-Offs For Modeling Light Sources and Surface Scattering
  Modeling light sources and surface scattering optical properties is a crucial consideration for simulating illumination systems that correlate with how a system will perform in reality. This presentation explores the trade-offs between simple and complex simulation models of light sources and surface scatter properties.
  
  
• Demystifying Étendue
  Étendue is often used to characterize the fundamental performance limits for illumination systems, especially systems that use extended sources. Despite its value in illumination design, the term étendue is often considered confusing. In this talk, we’ll demystify étendue by examining numerous common examples. These examples show how étendue is directly related to performance limits for some system but not others.
  
  
• Effective Usage of LightTools 2018
  The 2018 edition of Effective Usage of LightTools has tips on positioning and aligning LightTools geometry, and reviews methods of analyzing surface profiles with LightTools capabilities.
  
  
• Statistical Variation of Color Uniformity for Solid-State Illumination Systems
  In many illumination systems, multiple LEDs of the same color are needed. This presentation investigates the impacts of LED differences on color uniformity of a 6-LED Center High-Mounted Stop Lamp.  The creation of both suitable spectral tolerances and appropriate performance metrics for a tolerance analysis is explained.
