Use Cases provide short examples how VirtualLab works.
We invite you to explore the amazing features of our recently released VirtualLab Fusion User Experience Edition. Either you are already a customer or you are a trial user, you will find interesting and helpful information in our Use Cases. In what follows we give you an initial selection of Use Cases, which help you to getting started with Virtuallab Fusion.
- Structure of VirtualLab User Interface

During the User Experience Program, we will also work on a more elaborated document on Getting Started based on a collection of Use Cases. Let us know your opinion about the most important features you like to learn about in such a Getting Started document. We await your suggestions and requests at user-experience(at)lighttrans.com.
We have prepared a small tutorial for you:
The analysis of the diffraction efficiencies of gratings is the typical modeling task with gratings. The efficiencies follow from the Rayleigh coefficients. Both quantities are given for each of the diffraction orders of a grating.
VirtualLab Fusion enables the calculation of efficiencies and Rayleigh coefficients by the fully vectorial Fourier Modal Method (FMM). This is done by the Grating Order Analyzer, which can display the efficiencies and Rayleigh coefficients of the distinct orders in various ways.
This use case introduces the Grating Order Analyzer.
This use case demonstrates how to use the Multigraph Mode for diagrams showing 1D Numerical Data Arrays. Several setup options will be discussed.
The use case also explains the specification of default values for the Multigraph Mode via the Global Options dialog.
This use case demonstrates how to use the calculator for spherical lenses. The calculator can be used to evaluate the easy lens equations, including the lens maker equation.
Within this use case we also demonstrate to usage of the calculator in combination with the spherical lens component in VirtualLab
This use case demonstrates how to configure 1D diagrams in a way they meet the demands of an appealing presentation. Diagram are used to visualize for example numerical data arrays. Data Arrays are numerically the base type for representing sampled data within VirtualLab.
The configuration of 1D-diagrams (used for y=f(x)) will be shown in this use case.
This use case demonstrates how the material catalog can be used within VirtualLab. An overview of the possibilities to access material information will be given.
It is shown how materials can be load from catalog and saved for further using.
The material catalog can be access via the corresponding ribbon item in the catalog ribbon.
This use case describes the basics about the global options dialog of VirtualLab.
Global options are used for different aspects of VirtualLab, for example view or performance settings. The general structure of the edit dialog of the global options is explained.
The global options dialog can be opened by clicking on the Global Options item in the File menu.
This use case demonstrates how the Ray Tracing engine within VirtualLab can be used to evaluate the performance of a collimating lens system with a high numerical aperture. The 2D and 3D ray tracing analysis are shown. In addition a programmable detector is used to evaluate the following customized merit functions on the ray tracing result: The wave front error per ray and also the RMS value of the wave front error for collimated light.
This use case shows the capability of the geometric field tracing plus engine to calculate the light distribution generated by a lens system with a high numerical aperture. It is shown that all harmonic field components are available within the geometric field tracing plus engine. We will also use the result of the geometric field tracings plus engine and to perform a diffractive propagation step to calculate the diffraction spot within the focal plane.
This use case demonstrates how VirtualLab can be used to analyze a lens system with a high numerical aperture. We will discuss the 3D ray skeletton as well as the two dimensional spot diagrams before and directly in the focus. In addition VirtualLab can be used to measure the spot size of the spot in the focal plane.
