Release History Wyrowski VirtualLab Fusion

VirtualLab is always delivered with an automatic installation routine: a complete base installation or an update that requires the latest base installation. Each update requires a valid update service.

VirtualLab Fusion User Experience Edition (Build 6.2.1.15) (update)

The next version of VirtualLab Fusion User Experience Edition (build 6.2.1.15) has been released. VirtualLab Fusion 6.2.1.15 is a service release. The complete release notes can be found here.

July 2016.

VirtualLab Fusion User Experience Edition (Build 6.2.0.27) (update)

The next version of VirtualLab Fusion User Experience Edition (build 6.2.0.27) has been released. There are many improvements – please have a look at the complete release notes which can be found here.

In particular for the optimization of optical systems several improvements have been added. VirtualLab allows now the coupling of parameters which gives much more flexibility for design problems and a tolerance analysis. Further the interface to the robust design optimization tool optiSLang has been improved and design projects can be setup much simpler now, see our webinar on YouTube.

VirtualLab Fusion User Experience Edition (Build 6.1.0.20) (update)

The next version of VirtualLab Fusion User Experience Edition (build 6.1.0.20) has been released. The complete release notes can be found here. Besides other improvements, this time we focused on new features in:

  • Fully vectorial grating modeling
  • Customization and user programming

With the Grating Toolbox we provide tools for the analysis and optimization of gratings for different applications. The basic modeling technique is the rigorous Fourier Modal Method (FMM). It provides the user with the near field of the grating in transmission and reflection. The new Grating Order Analyzer provides the diffraction efficiencies and the Rayleigh coefficients of all orders of interest. This is done in the form of tables but also graphically, by using different concepts of the presentation of the orders together with the quantities of concern. It enables a convenient and user-friendly way to investigate diffraction gratings.

VirtualLab Fusion User Experience Edition (Build 6.0.0.57) (base installation)

After almost two years of hard work on the next generation of VirtualLab technology, we are happy to enter the final development period with the start of our User Experience Program. With this program, we would like to share our achievements with you and to encourage you to send us your feedback and suggestions. All your input will be taken into account in the next few months. After some months of further development VirtualLab Fusion will be finally released. Therefore, we would like to give you the unique chance to contribute to the final features with your own ideas and needs.

  • The entire menu structure has been changed to Ribbons. That allows a fast and intuitive access to objects and their parameters during your design workflow.
  • The Field Tracing engine is renamed to Classic Field Tracing and remains otherwise unchanged. Therefore, with VirtualLab Fusion you can still do everything you could do with VirtualLab 5! All your lpd files work in VirtualLab Fusion as before when you use the Classic Field Tracing engine.
  • In addition, many new features make it much easier and more efficient than before for you to carry out your work. For instance, we have added a powerful Parameter Overview to enable fast access to all the parameters of a system. A collection of other useful new features, which improve working with VirtualLab, is presented in New Features Overview.
    In addition to the Classic Field Tracing engine, we have added a full Ray Tracing engine that provides all the ray-related parameters in modeling. For us that is the basis to offer you everything you expect from ray tracing software. Thus, in the User Experience Program we ask you to specify your requests and needs for additional features of our ray-tracing engine. We definitely intend to tackle classical lens design tasks as well. Get a first insight into our ray tracing engine through a use case example.
  • By replacing conventional rays by smart rays, we obtain geometric field tracing, which is a physical optics technique. We combine that with optional diffractive modeling techniques in the source and detector regions and obtain the new Geometric Field Tracing Plus engine, which is included as a Beta version in the VirtualLab Fusion User Experience Edition. We have decided to provide you with this Beta version now, since it enables several important new modeling opportunities which were not available before. One example can be found here. During the User Experience Program, we will provide you with more examples in the form of use cases and application scenarios, which will explain the power of this new engine and how to use it. The engine will be further improved and finalized until the end of the User Experience Program and the subsequent release of VirtualLab Fusion.
