Developped in 1999 by LightTrans experts, VirtualLab™ is the new generation software. The concept of Field Tracing (as opposed to classical ray tracing software) unites the techniques ranging from geometrical optics to electromagnetic approaches. It enables the simulation of  optical systems including diffraction, partial coherence, polarization, interference and vectorialeffects.

Unified Optical Modeling

Modern optical systems may contain a large variety of optical components as for example refractive, diffractive, hybrid, Fresnel and GRIN lenses, diffusers, beam shapers, diffractive beam splitters, computer generated holograms, phase plates, gratings, elements with free form surfaces and micro lens arrays. In addition light sources with different properties as for example degree of coherence, color and polarization can be used. 

An efficient optical modeling requires the simulation of all of these types of components and sources with a high physical accuracy on a single software platform. LightTrans developed the concept of Field Tracing to perform these simulations. Field Tracing unifies optical modeling techniques ranging from geometrical optics to electromagnetic approaches. It enables the simulation of optical systems including diffraction, interference, partial coherence, aberrations, polarization and vectorial effects. 


The VirtualLab™ package integrates several toolboxes allowing for the analysis of systems, design of diffractive optical elements, design of beam shapers, analysis of gratings, analysis of laser resonators as well as the shaping and homogenization of LED light.
