in the fast optical design software VirtualLab Fusion
Our fast optical design software VirtualLab Fusion supports light shaping by freeform surfaces, diffractive beam splitters and pattern generators, diffusers, and general arrays of micro-optical components, including, but not limited to, micro-lens arrays.
VirtualLab Fusion, the fast optical design software enables the optical design and the simulation of illumination systems for shaping, splitting, diffusing and homogenization of both laser and LED light. The emphasis of the software package is on the use of lens arrays, diffractive optical elements and cell arrays consisting of gratings, mirrors and prisms. For the designed components, fabrication data can be exported in several formats including STL and GDSII; the interaction with SLMs is also supported. Fast physical optics simulation and optimization algorithms enable the design of these optical elements. The modeling takes into account diffraction, interference, polarization and degree of coherence.
The thorough investigation of interferometers, spectrometers and the imaging quality and resolution limit of microscopes with conventional or structured illumination is enabled by fast physical optics.
Optics has provided throughout history the means to perform incredibly accurate measurements, a vital cog in catapulting the potential of science and technology. An analysis of metrology systems unavoidably requires the consideration of physical optics effects (coherence, polarization, interference, diffraction, etc.) to yield realistic, well-informed results. VirtualLab Fusion provides the necessary tools for such an analysis, taking advantage of the fast physical optics theory to, moreover, facilitate fast simulations.
Modeling lens systems by fast physical optics provides reliable PSF/MTF evaluation including ghost images and partial coherence, and the inclusion of gratings, HOEs and diffractive lenses.
Imaging systems constitute one of the historic cornerstones of optics. Their applications are manifold, and consequently, so are the requirements placed upon them: inclusion of diffractive elements alongside traditional lenses, computation of advanced PSFs/MTFs, consideration of multiple reflections in the system… VirtualLab Fusion helps you successfully undertake all of the above in the simulations of your optical systems via its fast physical optics model, implemented with a friendly user interface.
Fast physical optics provides a cogent model of laser sources, while also considering diffraction, interference and polarization, as well as granting access to any beam parameter of concern.
The simulation of laser systems supports single- as well as multi-mode, continuous wave (cw) and pulsed laser sources. Laser systems can be designed including lenses, mirrors, diffractive optical elements, gratings and holograms. VirtualLab Fusion provides fast and accurate field and ray tracing engines in a single piece of software with an intuitive user interface.
Virtual and Mixed Reality
VirtualLab Fusion provides non-sequential modeling of multichannel waveguide imaging systems including wavefront error, energy flux and PSF/MTF evaluation as required for VR, AR and MR
In modern display technology, the imaging channel or, in other words, the lightpath from the image panel to the human eye, must be compact while also introducing a lateral offset between panel and eye. In addition, we typically need multiplexing into many imaging channels to provide the image to the eye at different positions. To this end waveguides with gratings are of increasing interest. VirtualLab Fusion enables non-sequential ray and field tracing modeling and design of such devices, including electromagnetic inclusion of grating effects, automatic detection of all relevant lightpaths through the waveguide, and even the calculation of the PSF/MTF for the multi-channel input for any eye position, including the consideration of the partial coherence of the channels.
