Pi Imaging Technologies focuses on the development of single-photon avalanche diode (SPAD) arrays and image sensors, engineered using cutting-edge semiconductor technology. SPAD is a type of photo-detector that can detect very weak light signals, even down to the level of individual photons. Founded in 2028, the company has introduced the world’s first SPAD-based camera, and today’s products include a range of point SPADs, linear SPADs, SPAD cameras, and custom devices aimed at applications across life sciences, industrial applications, quantum technology and more. 

Following successful a collaboration with Carl Zeiss GmbH, Pi Imaging was acquired. Zeiss is the leading provider of light, electron, X-ray microscope systems, correlative microscopy and software solutions leveraging AI technologies for industries such as life sciences, materials and industrial research, as well as education and clinical routine applications.

SPAD detectors from Pi Imaging Technology SA will complement the current and future sensor technologies used in ZEISS high-end microscopes. The combination of Pi Imaging Technology SA’s technology and ZEISS microscopy solutions will enable innovative solutions for researchers in the field of high-end fluorescence microscopy in the future. The integration of SPAD technology into ZEISS microscopes improves both the quality and throughput in microscopic imaging in life sciences, and so opens new technological possibilities and applications. Since SPAD detectors offer exceptional sensitivity in low-light conditions, they allow researchers to study molecular environments and interactions with remarkable clarity, for example.

“We achieved pioneering milestones by being the first company to integrate a SPAD array into a commercial microscope in 2020 and subsequently introducing the first SPAD camera to the market in 2021”, says Michel Antolovic, Managing Director and co-founder of Pi Imaging Technology. “I am very pleased that after many years of trusting collaboration with ZEISS, we are now taking the next step and integrating our entire business into the ZEISS Group. We will merge our innovation capabilities and together shape the field of light detection.”

Following the acquisition, ZEISS customers can expect advanced imaging applications with the next generation of detectors. The companies are also active in other fields, including spectroscopy, scientific imaging, low-light imaging, and high-speed imaging. Their objective is to collaborate on advancing these fields.

PI Imaging will retain its headquarters Lausanne location and all of its employees.
