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!

Pieter Smid, ASML

„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.

Dr. Fabian Patrovsky, CDA GmbH
