One of VirtualLab Fusion’s strengths has always been, from its inception twenty-five years ago this year, its capacity for the modeling, simulation, design and optimization of diffractive structures. But in the intervening quarter of a century it has become much more than that: through its revolutionary approach of offering a catalog of multiple interoperable modeling techniques on a single software platform, VirtualLab Fusion allows its users to navigate the ever-relevant compromise between accuracy and speed with full flexibility and control. With VirtualLab Fusion, your simulations of complex optical systems containing all manner of components can be as accurate as needed, and as fast as possible!

With this webinar we go back to our roots and put the focus on diffractive optical elements (DOEs), but without forgetting how far we have come: we place DOE modeling and design in the context of modern VirtualLab Fusion technology as one type of optical component which can be combined with many others to create a complex system. A helpful tool in this context is the iterative Fourier transform algorithm (IFTA), which allows for the design of diffractive beam splitters, light diffusers, and beam shapers. In this webinar we show two scenarios where we demonstrate the design, modeling, and analysis of diffractive optical elements (DOEs), including full system simulation.

  1. The first example will be a beam-splitting application for the generation of a light mark with focused spots.
  2. The second example will be a light-diffusing application for the generation of the LightTrans logo high on the façade of a building.

For the examples in this webinar we put the IFTA design and analysis process in the context of our state-of-the-art engine, to benefit from the advantages of our latest technology in the system simulation. See for yourself – register for the webinar below!
