Hembach Photonik: Your partner for the development and analysis of optical systems and developer of RayJack ONE®

General information

Company profile

Hembach Photonik GmbH is an engineering partner for the development of illumination, sensor and imaging optical systems and supports customers with optical design and analysis services, optical software, and training. We are leading European supplier for stray light analysis located in Schwabach near Nuremberg, Germany.
Our main software product is RayJack ONE®, a multi-purpose non-sequential ray-tracer developed by Hembach Photonik and funded by the European Space Agency. It is a full-fledged optical design and analysis tool and offers cutting-edge algorithms for radiometric calculations and stray-light simulations, as well as an unparalleled toolbox for optical analysis.

Products & Services

• Engineering Services, with a strong focus on stray light analysis.
• RayJack ONE®: multi-purpose non-sequential ray-tracer. Especially suited for design and analysis of non-imaging optics (illumination and sensor systems, stray light). Implements novel techniques for radiometric calculations and stray-light simulations, and an unprecedented tool-set for optical analysis. A Python-based intuitive scripting environment offers maximum flexibility and control over simulations.
• Distributor of SYNOPSYS™: a powerful lens-design software for the full chain of the lens-design process (created by Optical Systems Design, LLC (USA))
