LightTools V2026.03: Illumination Design & Optical Simulation Software LightTools 2026.03 is Keysight Technologies’ latest release for 3D optical engineering and illumination design. The software has transitioned from Synopsys to Keysight, with this version retaining the version numbering convention of the previous owner but shipping under the Keysight brand . This release focuses on eliminating simulation bottlenecks and supporting next-generation applications . Key New Features in V2026.03 GPU-Accelerated Forward Ray Tracing Significant performance upgrade with 10× to over 50× speed gains depending on model complexity and hardware . Supports point and surface sources, multiple receiver meshes, volume scattering models (Gegenbauer, Henyey-Greenstein), measured BSDF, Microfacet scatter models, and optical cementing . Enables high-fidelity simulations with hundreds of millions of rays much earlier...

LightTools version 2024.03 provides capabilities that make LightTools a more efficient, versatile illumination analysis and design tool than ever before. Key improvements include: Sequence ray tracing, an innovative simulation mode for even faster analysis of stray light paths. A global optimization engine that can be used to explore a broader solution space – a new method that supplements the capabilities of the local optimization engines available in previous releases The capability to include temperature and pressure variations for the index of refraction. This capability lets you model environmental effects in CODE V and transfer the model to LightTools in an Optical System File. Expanded capabilities for thin film stack coatings enable designers to easily modify a stack in LightTools. You...
