Prof. Dr Marco Beijersbergen

founder & managing director


Marco Beijersbergen is founder and managing director of cosine. After his PhD in laser physics and optics at Leiden University in 1996, Marco recognised that there is a need for a company that offers commercial services in physics. The success of cosine has proven him right.

Marco has strong interest in the physical principles behind the development of scientific and industrial instruments. He not only applies that to the benefit of cosine’s customers, but he also shares his views and thoughts with physics and astronomy students at Leiden University, geophysics students at Vrije Universiteit Amsterdam and space engineering and management students at the International Space University in Strasbourg.

Exchanging ideas about unsolved technical and physical problems is what Marco loves to do. He would like it very much if you would like to discuss your technological challenge with him and find out what cosine can do for you.
