Milestones
Our journey reflects the determination of scientists who challenge the boundaries of industrial illumination and translate system requirements into verified performance.
2009
Incorporation of neonsee GmbH by Martin P. Maier as a spin-off from the International Solar Energy Research Center (ISC) Konstanz, with an initial focus on characterization systems for solar cell research and development.
2012
First sun load and burning glass effect projects in the automotive industry for Mercedes Benz, Magneti Marelli and ZKW Lighting Systems.
2015
Development of a highly collimated solar simulator for satellite sun sensor calibration at German Aerospace Center (DLR).
2017
Selected by the European Space Agency (ESA) as the prime contractor for sun simulation projects.
2018
Shareholder restructuring and integration in the company network of SpaceTech Immenstaad (STI) and CarboSpaceTech (CST).
2023
Successfully filed the initial patent application for our proprietary RFsun freestanding plasma lighting technology. The patent has been granted in 2025.
2025
Sale of the solar simulation business unit to halm elektronik GmbH, accompanied by a shareholder restructuring to fully focus on RFsun research, development, and productization.

Martin Pirmin Maier
Founder | Shareholder | CEO
Martin Maier is a physicist specializing in semiconductor and optical technologies. He has led international development projects on the characterization of solar cells and optical systems. He has worked on projects for institutions such as Daimler AG, Corning, Emcore, Azur Space, the Indian Institute of Science (IISc) in Mumbai, and the German Aerospace Center (DLR). He developed lighting systems for the National Aeronautics and Space Administration (NASA), the Japan Aerospace Exploration Agency (JAXA), and the European Space Agency (ESA). At SpaceTech (STI) in Immenstaad Martin Maier was responsible for the set-up of a fully automated production line for satellite solar arrays. At ISC Konstanz he is responsible for the business development in the area of low-cost silicon solar cells for space applications.
Reinhard Gregor Birmuske
Shareholder | CTO
Reinhard Birmuske earned his advanced master’s degree in physics from the University of Konstanz, graduating with highest honors. He supervised a research project at the University of Giessen aimed at improving high-frequency ion thrusters for satellite in orbit propulsion. As a system engineer at SpaceTech (STI) in Immenstaad, he was involved in numerous international space projects, including serving as project manager for the RIME antenna (“Radar for Icy Moon Exploration”), which is currently on its way to Jupiter as part of the ESA JUICE mission. Most recently, Reinhard Birmuske worked as a product manager for SAX Power, where he contributed his expertise to the development and scaling of innovative battery technologies. In 2025 Reinhard Birmuske became shareholder of the neonsee GmbH.
