Company Description
Optical Simulation and Design with LightTrans VirtualLab™ 5
The field tracing software provides suitable modeling and design techniques based on unified optical modeling, enabling new technologies for the design of optical systems. Field tracing is based on considering harmonic fields and provides more information than ray tracing about the light in optical simulations. This allows VirtualLab™ to take into account diffraction, interference and polarization effects and aberrations during optimization which generalizes classical methods of optical modeling and design. In particular, the design of different types of micro-structured elements being used in highly compact optical systems are supported.
Several optimization methods are offered, including local and global parametric optimization, the iterative Fourier transform algorithm and a design algorithm for grating cells arrays – for the design of diffractive beam splitters, diffusers, beam shapers, elements for shaping LED light, gratings, and the optimization of laser systems.
The new Lighting Toolbox provides field tracing for the analysis and design of illumination systems. Field tracing enables the usage of new concepts with emphasis on the integration of microstructures and diffractive optics. That gives more flexibility for the design of compact illumination systems for the homogenization and shaping of LED light as well as light of other sources with highly divergent radiation.

| Optical Simulation and Design with LightTrans VirtualLab™ 5
LightTrans is going to present VirtualLab™ 5 – the new generation of our optical modeling and design software. VirtualLab™ is the first field tracer on the market. Instead of ray bundles, harmonic fields are traced through the system. Hence field tracing utilizes and provides more information about the light in your optical system. In short field tracing delivers results fully vectorial, as accurate as required, and as fast as possible.
The VirtualLab™ Starter Toolbox enables the simulation of laser optics, micro optical systems, diffractive optics, interferometers, imaging and illumination systems. Optical systems may contain refractive, diffractive, hybrid, Fresnel and GRIN lenses, diffractive optical elements, diffusers, beam shapers, diffractive beam splitters, computer generated holograms, phase plates, elements with free form surfaces and micro lens arrays.
VirtualLab™ enables the modeling and propagation of ultrashort pulses through laser systems. The propagation includes diffraction effects, interference effects, aberrations, polarization and vectorial effects. The pulse shape can be visualized depending on the lateral laser beam position.
Several real light sources, as for example, LED’s, Excimer lasers, multimode lasers, thermal sources generate temporal and spatial partially coherent light. The coherence properties of real light distributions can be included in simulations. |

| Parametric Optimization and 3D Grating Simulations
LightTrans continues with its trendsetting strategy in optics software development. The field tracer VirtualLab™ provides modeling techniques ranging from geometrical optics to electromagnetic simulation on one single platform. That offers an unsurpassed flexibility in modeling. The toolboxes of VirtualLab™ allow the investigation of micro-optics, diffractive optics, ultra-short pulses, laser resonators, LEDs, excimer lasers, gratings, photonics crystals, artifical materials, and much more.
VirtualLab™ 4.9 enables the rigorous analysis of 3D surface gratings, holographic gratings, artificial media, zero-order gratings, antireflection gratings and photonic crystals with features from nanometer to micrometer scale. Various customization features allow the analysis and optimization of gratings with user defined structures.
VirtualLab™ 4.10 enables parametric optimization for imaging, beam shaping and illumination systems. Based on field tracing techniques and an electromagnetic re-presentation of light, VirtualLab™ provides fully vectorial results as input for a great variety of merit functions that define the target of optimization problems. |
