LightTrans distributes "VirtualLab Fusion", which sets new standards in optical design software with its unique way of providing ray tracing and fast physical optics modeling and design techniques. LightTrans also offers physical optics training, consulting and engineering services based on "VirtualLab Fusion". Our wide range of applications includes: - Light Shaping - Imaging Systems - Laser Systems - Optical Metrology - Virtual & Mixed Reality Some highlights of our technology are summarized in the following points: - Physical optics modeling often as fast as ray tracing. - Easy switching between ray tracing and physical optics modeling. - Inclusion of Maxwell solvers for gratings, diffractive lenses and HOEs on planar and curved surfaces. - Switching between sequential and non-sequential modeling (forth and back) in the same system setup. - Design of diffractive lenses with export of fabrication data. Using the free trial version (https://www.lighttrans.com/de/resources/trial-software.html) alongside the sample files is the best way to evaluate the potential of VirtualLab Fusion.
