Pi Imaging Technologies acquired by Zeiss to advance high-sensitivity microscopy
25.07.2025
Pi Imaging Technologies SA, the Lausanne-based developer of SPAD-based imaging solutions, has been acquired by Carl Zeiss Microscopy. Known for launching the first camera built on single-photon avalanche diode (SPAD) technology, Pi Imaging will now contribute its innovations to Zeiss’s microscopy systems, with the aim of advancing imaging performance in life sciences and related fields.

Founded in 2018, Pi Imaging Technologies has established itself as a leading developer of SPAD arrays and image sensors. These detectors are capable of capturing extremely low levels of light—down to individual photons—making them ideal for demanding applications in scientific imaging, industrial sensing, quantum technologies, and fluorescence microscopy.
The company's portfolio includes point and linear SPADs, SPAD cameras, and custom solutions. Its technology allows for high-speed, high-sensitivity imaging, enabling researchers to study molecular behavior with greater precision and clarity.
Following a successful collaboration, Zeiss has acquired all equity shares and employees of Pi Imaging Technologies. The integration of SPAD technology into Zeiss's high-end microscopes will expand the capabilities of fluorescence imaging by increasing both throughput and image quality under low-light conditions.
Pi Imaging's detectors will complement Zeiss's existing and future sensor technologies. Researchers using Zeiss systems can expect improved performance in a wide range of applications, from life sciences to materials research.
The company, winner of Venture Kick, will continue to operate from its Lausanne headquarters, with all staff retained. In addition to microscopy, both companies are jointly exploring further opportunities in spectroscopy, low-light imaging, and high-speed scientific imaging.
