Cloud native EDA tools & pre-optimized hardware platforms
We are pleased to announce that LightTools 9.0 is now available. This release features the following major enhancements, along with many other improvements:
Direct-Sales Customers
Software and license key files for LightTools direct-sales customers are available on the Synopsys SolvNetPlus website.
Distributor Customers
For customers working with distributors, you will continue to obtain your software and license keys from your local LightTools software distributor. See the Synopsys Optical Solutions Group Global Contacts page for contact information. If your country is not listed on the page referenced above, please contact us at lighttools_support@synopsys.com for instructions.
If you use the OSG Floating License Manager to manage licenses for client computers running LightTools 9.0, you must install the latest version of the OSG Floating License Manager that is made available with LightTools 9.0. The OSG Floating License Manager software is available from the same source that provides your LightTools software (e.g., SolvNetPlus or your distributor). This version of the OSG Floating License Manager can also manage licenses for client computers running earlier versions of LightTools as well as CODE V and the LucidShape family of products.
Note that prior to installing the OSG Floating License Manager, you must first uninstall from the host server the following applications (made available with LightTools 8.7 or earlier) using the Windows Control Panel > Programs and Features:

User Materials Expanded to Support for Birefringence
Optical systems are increasing the use of polarizing elements including birefringent materials – materials that have two polarization-dependent refractive indices. This release allows you to define elements and analyze systems that are created with uniaxial and materials. The effects of wavelength and angle of incidence are automatically included in the analysis.

Simulation of polarization optical systems, including those using birefringence, can be better understood with the new polarization chart. This shows the state of the polarization so that optical systems can maximize the flux needed for a specific polarization.

Simulation Maximum Increased to 1000 Billion Rays
With one trillion rays now available for a simulation, the sampling limits are lifted for virtually all Monte Carlo simulations. This significantly expanded ray trace limit allows you to achieve better results for stray light analysis and luminance calculations.
Scatter Aiming Capability Extended to Measured BSDF Surfaces
The aim area feature in LightTools has been extended to support measured BSDF surfaces. This capability can significantly improve the efficiency and accuracy of stray light analysis in systems with measured BSDF surfaces.
Curved Surfaces Support in the Backlight Pattern Optimization Utility
With LightTools unique Backlight Pattern Optimization utility, you can now design display systems with curved panel shapes. With this capability, your design can conform to a dashboard, rotate about a user’s field of view, or conform to novel consumer electronic shapes, all with high spatial uniformity.

Usability Enhancements
More than a dozen modifications were made to improve usability in this release, including options for zooming in on a specific surface or object, to apply optical properties or align other components, for example. New layout options save the size and arrangement of your LightTools views, which enables you to restore a model with views positioned as they were when you closed it; you can also take a snapshot of a layout that can later be restored, which can be helpful when you share the model with a colleague as you collaborate on a design.
Improvements to the Utility Library
Improvements were made to the Light Guide Designer, Backlight Pattern Optimizer (BPO) utility, Parameter Analyzer, and Ray Path Analyzer, and the Surface Selection utility was added under Geometry utilities.
Enhancements to LightTools Libraries
Updates were made to the Example Model Library, the Materials Library, the Optical Properties Library, and the Glass Catalogs.
LightTools 9.0 and any 9.0 service releases will support both Windows 7 and Windows 10 operating systems for 64-bit applications. However, because Microsoft stopped supporting Windows 7 in January 2020, LightTools releases after version 9.0 will not support Windows 7.
For details about these and other features in LightTools 9.0, see the LightTools 9.0 Release Notes. If you have any questions about features in this release, please contact lighttools_support@synopsys.com.
We add new materials and measured BSDF files to our libraries often, and now you can access those files between releases. The LightTools Measured BSDF Library and Material Library for non-CODE V glasses and plastics is available on our Customer Support Portal.
