About us

LightTrans group is based in Jena in the state of Thuringia, the historical and present center of optics in Germany. Our products and services shorten or even enable development cycles of optical components and systems. All our activities are based on the Fast Physical Optics design software “VirtualLab Fusion”, which provides ray tracing and physical optics field tracing methods. Our products include optical design software, optical engineering, training and consulting as well as prototyping. Optical engineering solutions by LightTrans help you to minimize R&D costs and development time.

Products and services

VirtualLab Fusion – Fast Physical Optics modelling and design software

All the products and services of LightTrans are based on the physical optics design software “VirtualLab Fusion”, which provides ray tracing and physical optics field tracing methods. Light is represented by electromagnetic fields and diffraction, interference, polarization effects and aberrations are taken into account during the engineering process of optical elements and systems.

Applications include the waveoptical design and analysis of laser systems; control of ultrashort pulses; shaping, splitting and diffusing of light by diffractive optical elements; homogenization and shaping of LED and Excimer laser light; design of gratings and optimization of laser resonators.

LightTrans provides solutions for, among others, the following fields

  • Laser Beam Delivery
  • Optical Measurement
  • Spatial Light Modulation
  • Holographic Display
  • Laser Scanning
VirtualLab Fusion – Fast Physical Optics software

VirtualLab Fusion – Fast Physical Optics software

Highlights of the fast physical optics concept of the VirtualLab Fusion 2nd generation technology update are:

• Automatic modeling selection which makes physical optics modeling as easy as the application of ray tracing.
• Easy switching between ray tracing and physical optics modeling.
• Full flexibility of non-sequential modeling configuration
• Unsurpassed flexibility to define detector functions

Virtual and augmented reality glasses have brought forth a series of challenges for optical designers. VirtualLab Fusion offers the necessary tools to undertake the modelling and design of such devices:

• ray and physical optics simulations with
• both sequential and non-sequential tracing
• advanced PSF/MTF calculation
• rigorous model to calculate efficiencies of diffraction orders

are just some points that underpin the potential of VirtualLab Fusion when it comes to the modeling of NEDs.
