VirtualLab 4 from LightTrans is innovative, user-friendly software technology enabling practical solutions for today's and tomorrow's most challenging optical applications. VirtualLab 4, to be released in fall '08, will include easy-to-use flow chart diagrams to describe the light path through optical systems, provide automatic propagation algorithm operators, and incorporate session editors (wizards) to assist the VirtualLab user, thus allowing a much easier optical design/simulation process to save valuable time, money, and effort of non-experts as well as experts working in various technical fields of optics.
