SPAD Detector Arrays & Cameras

Pi Imaging Technology - a Zeiss company, provides advanced SPAD detector arrays and plug and play cameras designed for single photon level sensitivity. Our systems offer true photon counting and picosecond timing resolution for time resolved imaging. Each detector array is engineered for low noise performance, delivering high signal fidelity in both laboratory and industrial settings.
Backed by the ZEISS Group, our technology supports a wide range of applications, especially in the biophotonics field. Our product portfolio covers small SPAD arrays for point scanning, linear arrays for spectral applications, and high resolution cameras for wide field imaging. Beyond photon counting, users can access picosecond timing information, obtain live images, or integrate raw sensor data into custom electronics. This combination of flexibility, high-speed operation, and low noise imaging is typically not available in conventional CMOS or CCD cameras.
Our products address the critical challenge of capturing extremely weak optical signals while maintaining high temporal precision. Photon starved experiments that once required long acquisition times can now be performed in real time with orders of magnitude improvement in speed. Applications that rely on precise photon arrival times, such as fluorescence lifetime imaging, benefit directly from our built in time gating and time tagging technologies.
Key biophotonics fields served include point scanning and wide field fluorescence lifetime imaging, flow cytometry, quantum optics, confocal microscopy, and any research domain where photon statistics or single photon sensitivity is essential. Industrial users rely on our systems to develop high signal to noise imaging and microscopy products. Researchers gain access to high performance SPAD technology without the need to build custom electronics. Our SPAD arrays enable a new generation of high-speed, time resolved photonic instruments.
