Synopsys Introduces Improved Illumination Optics Design with New LightTools Version

Dec. 16, 2020
LightTools Version 9.1 brings enhanced LiDAR design features, increased ray tracing speed, and faster optomechanical modeling with SOLIDWORKS.

MOUNTAIN VIEW, Calif. -- Synopsys, Inc. (Nasdaq: SNPS) today announced the release of version 9.1 of its LightTools® illumination design software, which expands LightTools' comprehensive features and workflows for illumination optics design with new tools to model and analyze light detection and ranging (LiDAR), AR/VR, and biomedical systems. Additionally, version 9.1 introduces a Distributed Simulation Module that increases the speed of computation-intensive ray tracing, as well as improved optomechanical interoperability with Dassault Systèmes' SOLIDWORKS 3D CAD software.

"The feature and workflow enhancements in LightTools are tailored to help engineers focus on solving complex design challenges and delivering innovative optical systems to market sooner," said Stuart David, vice president of engineering in Synopsys' Optical Solutions Group. "SOLIDWORKS users working on optical designs can expect to speed up source characterizations. Engineers developing LiDAR systems can more easily perform time-of-flight analysis. And development of advanced applications for AR/VR, displays, and medical devices is improved with LightTools' comprehensive polarization analysis."

LightTools v9.1 update includes:

  • Efficiency enhancements to the LightTools SOLIDWORKS Link Module give illumination engineers more control and ease of use for optomechanical modeling. Users will experience faster model setup with the ability to control source placement and assign optical properties within SOLIDWORKS.
  • New design capabilities meet demanding requirements for LiDAR systems, AR/VR headsets, display technologies, and biomedical instruments. Users can design laser sources with Gaussian and Super Gaussian light distributions using spatial and angular apodization, as well as model and analyze polarizing elements with biaxial birefringent materials.
  • The LightTools Distributed Simulation Module can accelerate the simulation speed of large, computation-intensive ray trace processes over a network of computers. The module, which is useful for boosting ray trace speeds for stray light and luminance analyses, now supports forward and backward simulations.


LightTools v9.1 is available now. Customers with a current maintenance agreement can download this version from the Synopsys website using their SolvNetPlus account, or obtain the software from their local distributor.
