Optical Design Software - VirtualLab Fusion
06 – 07 March 2023 | 09:00 – 13:00 (CET)
I was fascinated by the almost limitless possibilities of encoding and combining different optical functionalities with simultaneous control of all relevant spot properties [...]. Great & fast support and teaching helped me to understand the physical principles behind and how to simulate them.
Alexander Graf, Novanta
I worked with different optical programs over the years and I can tell you frankly that VirtualLab Fusion is my favorite by far! Keep on the good work developing VirtualLab Fusion!

„VirtualLab Fusion offers excellent opportunities in research projects and is perfect for use in teaching, especially since there are many documented application examples available.“
Prof. Dr. Stefan Kontermann, Hochschule RheinMain
Nowadays ray tracing is not sufficient anymore. For a detailed analysis physical optics is required. VirtualLab Fusion is optimized for wave-optical simulations. The results we achieved are excellent. We can highly recommend VirtualLab Fusion. Not only the software is great, but also the support of the whole LightTrans team.
Dr. Benjamin Heck, Raylase GmbH
Excellent program, amazing capabilities, and very user-friendly interface.
Galina Machaviariani, Apple
VirtualLab Fusion is a very promising software that is helping in solving some peculiar diffraction issues that have been causing headaches to the community.
Federico Landini, INAF – Osservatorio Astrofisico di Arcetri
This is one of the most elaborate pieces of software I’ve ever had the pleasure of working with. My workflow now is not only faster and more pleasant, but also very well documented with little to no effort on that point.

Back to the Future of DOE Design – Part 1: Design & Rigorous Optimization of a Diffractive Beam Splitter
Back to the Future of DOE Design
Design & Rigorous Optimization of a Diffractive Beam Splitter
In the first part of our series on diffractive optical elements (DOEs) we would like to turn our attention to diffractive beam splitters which, in contrast to other DOEs like beam shapers and diffusers, are desired to generate a uniform discrete pattern. Because the working principle of these components is based on diffraction of the incident light by these patterned surfaces, DOE beam shapers and beam splitters can be designed to be much thinner and lighter than their refractive counterparts, but the small structure sizes required make them difficult and resource-intensive to simulate.
In this field, the fast, accurate and flexible simulation and design algorithms of VirtualLab Fusion play to their strengths: the advantages of different solvers like the Thin Element Approximation (TEA), Rigorous Coupled Wave Analysis (RCWA) and Fourier techniques for free-space propagation are combined to allow optical engineers to not just design the elements, but also analyze their behavior in complex systems.
As an example, we would like to present the design of a non-paraxial beamsplitter, which is further optimized by applying rigorous techniques. The document (linked below) offers a deeper look into our diffractive optical element and microstructure components.
Over the next two months we return to our roots and focus on diffractive optical elements (DOEs), but without forgetting how far we have come: We put DOE modelling and design in the context of modern VirtualLab Fusion technology.
In the upcoming webinar we showcase the design and analysis of diffractive optical elements acting as a diffuser and a beam splitter respectively. To that end, we employ the iterative Fourier transform algorithm (IFTA) optimization and, afterwards, study the performance of the resulting designs in a system, using VirtualLab Fusion’s interoperability of modeling techniques.
If you are a complete beginner, or if you would like to deepen or refresh your knowledge of VirtualLab Fusion, we suggest you join our Getting Started Online Training. This course, takes place directly before our topic-specific Online Training "Design & Analysis of Diffractive Beam Splitter & Light Diffuser", where we go into detail about the basic configuration and handling of our IFTA optimization and embed this process in two real-life applications. Both courses can of course be booked in combination, if you are interested in the whole package!
Take part in the courses and see for yourself!
We have reason to celebrate ! Good things come in pairs: This same year in which we commemorate our 25th company anniversary, we are also proud to announce our renewed nomination for his edition of the PRISM Award. Celebrate with us – join us at Photonics West!Read more
