Single-Photon Avalanche Diodes (SPADs) sharpen spatial and temporal resolution

Lausanne, March 3, 2022 — At Pi Imaging, in collaboration with PicoQuant, we are advancing the future of photon-counting technology. Single-Photon Avalanche Diodes (SPADs) offer picosecond precision in detecting individual photons, making them invaluable in applications from astronomy to life sciences.

SPAD arrays, particularly those based on CMOS technology, provide enhanced spatial resolution and signal-to-noise ratio (SNR), addressing challenges in confocal microscopy and other high-resolution imaging fields. Recent advancements, such as improved fabrication processes and optimized micro-optics, have overcome early limitations of SPAD arrays, making them ideal for time-resolved imaging and high-speed applications.

SPADs are transforming microscopy, including fluorescence lifetime imaging (FLIM) and high-speed imaging, by offering faster imaging speeds and higher accuracy. This progress, supported by our partnership with PicoQuant’s time-resolved fluorescence instrumentation, is enabling breakthroughs across a broad range of scientific fields.
