Our vision

Combining physics and engineering leads to more and better measurement solutions that find their way into society faster through a small, innovative company with some of the brightest minds.

About cosine

Our mission

To be one of the best companies in the world that combine physics and technology to bring new measurement solutions to our clients.

How we work

Our development process is led by a core development team, with the expertise you need. The work flow is structured into five phases: ideation, assessment study, feasibility study, product and scale up.

Our expert teams

The cosine team is an international team of about 50 people, mostly physicists but also astronomers, chemists, aerospace engineers, computer scientists and technicians, most with an academic degree and many with a PhD. Our three dedicated teams work closely together to achieve the best possible results for our clients. We use orthogonal thinking to create smart solutions.

High Energy Optics

X-ray, gamma-ray and particle optics, with applications in astronomy, material analysis and health.

Remote sensing

Space and aerospace, with applications in air, land and water.

Inspection systems

Imaging and sensors, with applications in food/pharma, health and oil/gas.


We connect academia to industry, combining science and high-tech. We work with a wide variety of partners, including companies, institutes and universities, in The Netherlands as well as internationally.

Our ventures

Specific product-market combinations can lead to a spin-off or a joint venture.

Bendit Orthopedics

Together with a passionate orthopedic surgeon cosine started a joint venture to reduce rehabilitation time and improve rehabilitation quality.


Our building houses 7 cleanrooms as well as in-house assembly and testing facilities, including: calibration, electronics, laser, optical, shock, thermal vac and vibration.

Our story

cosine was founded in 1998 in Leiden by Prof. Dr Marco Beijersbergen. Since then, we have come a long way.

For an impression of our story, we invite you read the article we published in Ruimtevaart magazine, published by the Nederlandse Vereniging voor Ruimtevaart (Netherlands Space Society) in 2018, to mark the occasion of our 20 year anniversary.

We are also happy to share a video of a lecture given by our founder Prof. Dr Marco Beijersbergen for the Koninklijke Maatschappij voor Natuurkunde Diligentia, the Royal Dutch society for Physics, in 2020.
