flexible modeling of Unified Optical Modeling Platform Electromagnetic Field Kernel VirtualLab™ is the only optical modeling software on the market based on a unified optical modeling platform. This platform guarantees full compatibility with all source models and arbitrary propagation techniques through components. Furthermore, light fields can be evaluated with any type of measurement specification by detectors. This technological advance offers you unsurpassed flexibility and accuracy in optical system modeling. By combining various toolboxes in

the VirtualLab™ product family, you will have all the necessary tools for your application at your disposal. Our scientists and engineers are continuously designing and improving an everincreasing number of sources, components and detectors. In this way, your VirtualLab™ will always be equipped with the latest technological capabilities. VirtualLab™ – Welcome to the next generation of optical modeling and design.

Tools VirtualLab™ 4 technology features a variety of new tools which make optical modeling and design easy, accurate and enjoyable. Light Path Editor and Light View: This tool allows you to select sources, components and detectors, fix their position in space, and specify the sequence in which the modeling should analyze the effects of components on the light field and the detector signals. A non-sequential generalization is planned for release in 2009. Parameter Run Editor provides you with a powerful method to define experimental series.

Session Editors feature a Wizard dialog to help you configure optical modeling tasks. VirtualLab™ Explorer assists you with managing your Virtual­ Lab™ sessions. Tolerancing Editor offers a user-friendly dialog for tolerancing your optical systems. This feature will be released in 2009. Optimization Editor helps you manage advanced optimization techniques. Standard diffractive optics optimization is featured in v. 4.0. More optimization methods will be released in 2009.

The Light Path View and Editor provide you with a userfriendly environment to configure optical setups in laser optics, micro-optics and interferometry. Each component is modeled separately using suitable propagation techniques.

VirtualLab™ features a unique concept for modeling color, polarization, and temporal and spatial coherence. The example here shows the dispersion of polychromatic light modeled by a blackbody power spectrum.

Selected Features

Light is represented by a single or a set of harmonic fields. In VirtualLab™ basic source models are used to generate harmonic fields with one or a set of wavelengths based on a user-defined power spectrum. Planar source models can be applied to model spatial partially-coherent light. They all use an elementary mode per harmonic field set member. Gaussian and customized laterally shifted modes are applied to LEDs, excimer lasers and VCSELs. Hermite and Laguerre Gaussian modes are used for multimode lasers. Also for planar sources arbitrary power spectra can be specified.

4 VirtualLab™ is the only software platform in the world, based on the unifed optical modeling concept

Components VirtualLab™ features a wide range of ideal and real components. Ideal components are based on the transmission technique used in Fourier optics. Real components are specified by their material structure. Each component is equipped with one or more specially designed propagation techniques which could include geometrical optics and electromagnetic modeling.

Detectors Detectors can be linked to any source or component for evaluating field quantities. The Virtual Screen displays the field in natural color, the polarization and details regarding the data structure of the field.

Analyzers Analyzers can be selected in a light path diagram to analyze specific aspects of a system or any of its parts. VirtualLab™ is equipped with tools to analyze coating, ABCD matrix modeling, ray-tracing modeling, eigenmode analysis and grating efficiency.

Numerics With the automatic sample option, VirtualLab™ handles the numerical parameters so that you can concentrate on the optics. Smart algorithms detect the best propagation technique in different regions of your system.
