Browse the Hub to find the Digital Twins that match your real-world components - whether they are sources, optical elements, objects, or detectors. Each twin comes with a detailed specification sheet that describes its model, inputs, outputs, and performance trade-offs, helping you choose the right one for your scenario.

If you need guidance, you can always contact our support team at support@lighttrans.com with your application details for personalized advice.

But what if a twin you need isn’t yet available? You have two clear paths:

1. Request it from LightTrans – Share what you’re missing, and we’ll provide roadmap information on when that twin can be expected.
2. Build it yourself with our Twin SDK – For expert users, our Software Simulation Kit (under active development) allows you to create proprietary Digital Twins, protect your intellectual property, and integrate them seamlessly into the platform.

Once your Digital Twins are available, building your system is straightforward. There’s no need to worry about software interoperability or manual data conversion. Simply place the twins in 3D space using absolute coordinates or smart relative positioning, just as you would arrange equipment in a lab.

Configure each twin to match your real-world parameters.

For example:

• Open or close optical channels (e.g., enable reflection effects on lens surfaces to model ghost images).
   
• Configure source twins from monomode to multimode, extended sources, or multi-wavelength spectra -enabling modeling of temporal and spatial coherence. Distributed computing in VLF can accelerate these multi-mode simulations effortlessly.
   
• Place detector twins anywhere in the system, even more flexibly than in a physical lab.

After setup, we recommend starting with the Ray Tracing Engine for a clear 3D visualization of your system layout. Then, switch to the Field Tracing Engine to unlock the full power of modern optical simulation on a Digital Twin platform.

For your first field tracing run, you can temporarily disable diffraction effects in free-space propagation between twins to concentrate on the optical effects of the twins themselves. Once confirmed, enable VLF’s intelligent automatic inclusion of diffraction, which ensures that diffraction is seamlessly included wherever it is needed in the system – for example, when light propagates into a focus.

Advanced users can fine-tune modeling parameters for even faster simulations, but this is optional – the steps above are all you need to get started.

Beyond detectors, VirtualLab Fusion offers specialized Analyzers – such as Distortion, Field Curvature, and Müller Matrix Analyzers – that perform system-level measurements and characterizations.

For design tasks, we support two approaches:

• Parametric Optimization Package – Optimize system parameters using merit functions based on detector and analyzer results.
   
• Generative Twins – Smart Digital Twins that internally configure their own parameters to meet specified optical functions (e.g., flat lenses, beam shapers, diffusers). This next-generation design capability is being expanded throughout 2026.

Check the Hub for available generative twins and share your design needs with us. We are eager to develop the generative capabilities you require.
