Welcome to Our Download Area

We provide you with an ever increasing selection of documents, which should help you to learn more about the potential and the usage of VirtualLab. We have new documents, especially all Use Cases, which have been developed for VirtualLab Fusion. Other documents refer to VirtualLab 5 or even before. Such older documents carry still a lot of useful information and all examples are ready to use with VirtualLab Fusion. Of course these older documents will be updated step by step.

You can search for keywords you are interested in using the Search command. Alternatively you can directly select a category from the list below. Four categories are of special concern to learn how to work with and benefit from VirtualLab:

  • Use Cases give you modular insight to individual features of VirtualLab Fusion. Some use cases also include sample files. Please switch to for the download of Use Cases.
  • Application Scenarios typically provide you with a Readme and VirtualLab sample files, which allow you to test and try a simulation or design yourselves. Some of the scenarios also come with an additional demo movie in which the use of the sample files is illustrated.
  • Tutorials come with movies or presentations in which basic techniques to work with VirtualLab are illustrated.
  • Modules and Snippets category offers various C# files with a associated ReadMe. Modules are C# files which solve special tasks which are not implemented as menu driven operations or Light Path Elements. You can run these modules within VirtualLab. Snippets are short pieces of C# code. They specify the functionality of the various programmable items (e. g. programmable functions and programmable interfaces) VirtualLab offers.

Other categories provide you with manuals, articles and technical notes.
