Optics Design

Overview

Our range of services

Fraunhofer ILT offers its clients comprehensive expertise in customized geometric-optical laser systems. Among others, it focuses its research and development on beam shaping, fiber coupling as well as simulating the generation and propagation of radiation.

Given power density distributions can be generated with customized freeform optics through the redistribution of power through refraction and reflection. For this purpose, Fraunhofer ILT develops complex optimization algorithms with which virtual prototypes are created, the properties of which are then checked with simulation software. Freeform optics are used, for example, in LED lighting or in laser systems. Even materials with special properties are used for other optical systems. Thanks to the high refractive index of 2.4 and the high thermal conductivity, diamond allows, for example, dimensions of laser optics to be reduced drastically. Together with the Fraunhofer institutes IAF and IPT, Fraunhofer ILT has developed a laser cutting head that is 90% lighter than conventional components compared with glass optics and is very suitable for laser cutting processes.

The range of services offered by Fraunhofer ILT cover R&D in design and simulation, experimental studies on laboratory models, the development of industry-related, certified prototypes and comprehensive technology consulting as well as market research and feasibility studies.
