The Excelitas family of Single-Photon Counting Modules (SPCMs) are self-contained modules that meet the low-light-level detection demands of confocal microscopy, fluorescence, luminescence, and TCSPC, particle sizing and Quantum Communications.

Our SPCMs offer market-leading Photon Detection Efficiency (PDE), low after-pulsing, highest uniformity over the active area, high linear dynamic range, and low dark counts.
