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.

Timeline of cosine


cosine expands in Italy with new facilities. cosine Remote Sensing is expanding its offices in Benevento, Italy, and establishing new collaborations with Italian partners.


cosine and the European Space Agency (ESA) have signed the next stage of the development contract regarding Silicon Pore Optics (SPO) X-ray mirrors for the Athena mission. This step aims to further prepare the high-resolution X-ray optics for the production phase.


cosine expands cleanroom facilities. This extension was required for the development of the advanced X-ray optics for the future X-ray telescope ATHENA of the European Space Agency, as well as the development, assembly, verification and testing of the HyperScout series of miniaturized Earth observation instruments suitable for nanosatellites.


First AI image from space in history delivered by HyperScout 2. For the first time an image was processed in space using artificial intelligence. The image was processed by the tailored AI hardware of HyperScout 2, a miniaturized Earth observation instrument that is developed under the leadership of cosine.


Hyperscout 2 in orbit. Hyperspectral imaging including thermal and artificial intelligence.


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


Hyperscout 1 in orbit from the Jiuquan Satellite Launch Center in China.


Composite structure integrity sensors delivered.


Single photon laser altimeter breadboard delivered.

HyperScout Team

cosine welcomes 40th employee.


Design for US X-ray telescope.


Digital finish timing cameras developed for athletics.


Moved to Oosteinde 36 Warmond, opening labs.


cosine sponsors Rijksmuseum Boerhaave.


cosine wins Herman Wijffels price for fish freshness measurement.


Airborne multi-functional air measurement system delivered.


Nightpod camera for the International Space Station delivered. NightPod is an intelligent tripod head that is used to accurately rotate a SLR camera, potentially with a large tele-objective, to track objects from the ISS Cupola module.


ERB2 stereoscopic camera for the International Space Station delivered. The European Recording Binocular 2 (ERB2) was a stereoscopic 3D video camera built for use in space. ESA contracted cosine in September 2008 to design ERB2, after the positive results of its predecessor ERB1, which had already been operating and functional…


We founded 3D-One to focus our activities in the area of 3D cameras. Specialized 3D cameras are used for applications ranging from videoconferencing to security.


Gamma-ray scintillator detector for planetary missions.


Silicon Pore Optics designs delivered for telescope accommodation study for XEUS.


Design delivered for a highly integrated payload suites for a Mars mission.


First Silicon Pore Optics built: Gen1 robot, first SPO stack, proof of principle, co-inventor of patent.


Offices and labs opened in Leiden.


cosine Research BV and cosine Science & Computing BV founded.


The development of the XMM science simulator was completed under the coordination of cosine staff. The XMM satellite was later launched in August 1999 after the simulator had been developed to test and validate the supporting ground segment.


The foundation of cosine. On 5 January 1998, Prof. Dr Marco Beijersbergen founded cosine.
