Optical simulation

Optical systems in the digital test lab

In our advanced development processes, we rely on comprehensive simulations to design optical systems perfectly even before the first prototype is built. The spectrum ranges from standard ray tracing methods, which precisely map ray paths, to wave optics approaches for investigating complex diffraction and interference effects, to finite element analysis (FEM) for mechanical and thermal stability. This allows us to identify potential weaknesses early on in the project and derive targeted optimization measures.

Comprehensive view: Thermal, acoustic, photoacoustic, and gas flows

In addition to solely visual characteristics, other factors often play a decisive role. We therefore use our digital twin to integrate temperature curves, acoustic vibrations, and photoacoustic effects into our simulation models, thus testing the performance of the system under realistic operating conditions. At the same time, we can use flow simulations – e.g., of gas flows – to identify and evaluate potential impairments caused by particles or heat transfer within the system.

Integration into CAD and acceleration of development cycles

To enable adjustments to be implemented quickly, we've integrated direct interfaces between the simulation programs and our CAD tool. Thus, even the smallest mechanical changes can be examined directly for their optical effect, minimizing sources of error and significantly shortening development cycles. The complete documentation of the simulation steps also enables efficient collaboration between different departments, such as design, measurement technology, and software development.

Reliable prediction– confident decisions

Thanks to extensive, interdisciplinary analyses, we can make reliable predictions about the future operating conditions of an optical system. Iterative adjustments in the digital test lab reduce risks, lower costs, and accelerate overall development. We are thus relying on an innovative approach that has proven successful in many projects and reliably meets customer specifications.
