On-Site VirtualLab Fusion Training
20 – 24 November 2023
09:00 – 16:30 (CET)
Registration Deadline is 15 November 2023 | Limited to 12 participants
Navigating the delicate compromise between the accuracy of the results and the speed with which those results can be generated is an unavoidable part of simulation technology. The optical modeling and design software VirtualLab Fusion provides its users with the necessary flexibility and control to strike the right balance between accuracy and speed every time, through its interoperability of modeling techniques on a single platform.
Two-Part Course in Jena
Join this two-part on-site course at the LightTrans International headquarters in the German town of Jena to learn how to work with VirtualLab Fusion software so that you can get the most out of its cutting-edge technology, regardless of your field of application.
The course consists of an
- Introduction part (3 days, Monday–Wednesday), where we will start from complete beginner level and cover the most important aspects of the software from a general point of view, using use cases from different fields of application to illustrate the features and tools of the software; and an
- Gratings part (2 days, Thursday & Friday), where we will build on the concepts explored during the introductory section and apply the techniques to the modeling and design of systems containing gratings and meta-structures.
It is possible to register for either of the two parts of the course, as well as for both of them together.
The course will be taught by experts of the Optical Engineering team at LightTrans. Their daily work in direct contact with users of VirtualLab Fusion from all over the world means that not only do they have in-depth knowledge of the software and how it works, but also, crucially, of how best to put it to use in order to satisfy the requirements of a wide range of (currently in-demand) fields of application.
Below you can find a detailed agenda of the topics we plan to cover during the course. During the course we will work with the latest release, 2023.2, and we will of course present the most exciting new features of this version!
