Wyrowski Photonics was founded in 2014 as a spin-off of LightTrans GmbH and fully concentrates on the development of the optical design software VirtualLab Fusion and customized software solutions based thereon.

VirtualLab Fusion provides both ray tracing and a smart approach to physical optics modeling, field tracing, which produces fast and accurate results. With geometric field tracing Wyrowski Photonics presents its new breakthrough technology. It constitutes a fast Maxwell solver inspired by geometrical optics. Together with numerous diffractive-field-tracing techniques it is the next big step to provide our users with a unified field tracing experience in VirtualLab Fusion. LightTrans GmbH distributes VirtualLab Fusion alongside a network of local distributors worldwide.
