VirtualLab Fusion 2026.2 strengthens practical optical engineering workflows, expands the available set of Optical Digital Twins, and improves everyday work in optical design, modeling, and analysis.
Surrogate-model evaluation is expanded for metalens design, making it easier to inspect trained models, check valid parameter ranges, and use surrogate-based results transparently. The release also introduces the new Wavefront Phase Modifier twin family and adds aperture-capable variants for selected ideal plate components.
Several workflow and usability improvements make working with VirtualLab Fusion more transparent and robust. Region handling has been improved for geometry- and region-based modeling tasks. New global application settings give users more control over internet connection handling and global user interface customization via themes.
VirtualLab Fusion 2026.2 also refines public twin names and codes to improve terminology, consistency, and identification in the Optical Digital Twin Hub. For developers and advanced users, the new VLF Programming Reference adds improved navigation, search previews, dark mode support, and links to Microsoft .NET documentation.
Surrogate Model Evaluation and Query Tools
VirtualLab Fusion 2026.2 extends the surrogate-model workflow introduced for metalens design in VirtualLab Fusion 2026.1.
Surrogate models can now be evaluated directly, making it easier to analyze their optical response before using them in a metasurface design workflow.
The new query tools include Forward Query (1D), Forward Query (2D), and the Design Related Scan with its Linear Common-Phase Design Query.
These tools help users inspect how local optical quantities depend on wavelength, incident angles, polarization, and structure parameters.
The design-related workflow also supports the evaluation of common-phase behavior, structure selections, and quantization effects.
