SPC3

The SPC3 series single-photon counting cameras are based on the new Single Photon Imaging Detector (SPID), which enables parallel single photon counting by means of a monolithic array of 2048 SPAD (64 rows by 32 columns) with integrated counting electronics. SPID smart pixel architecture allows fast photon counting up to 96 kfps, with negligible dead-time among frames. At the maximum frame-rate, photon counting dynamics is 8-bit, but camera processing electronics allows noiseless frame binning, thus providing higher dynamics at lower frame-rates.

Each pixel has three 9-bit indipendent counters, two of them with up-down mode for lock-in acquisition. Three indipendent hardware gate inputs (one of them can be also controlled by SW) enable counting only during specific time-windows for each selected counter, which means that the SPC3 can be used very efficiently for indirect ranging measurements (iTOF), i.e. the SPC3 measurement will be based on the “photon counting” of back reflected photons within well-defined time-slots, synchronous with the burst illumination or the CW modulation of a dedicated illuminator. Such “indirect” TOF measurements based on the “digital” count of single photons will positively compare with the standard “analog” approach, impaired by “analog” noise and limitation in SNR and sensitivity.

SPC3 camera has also built-in FLIM capabilities by exploitng the Time Gating technique.

SPC3 camera is equipped with a USB 3.0 connection to enable fast data upload to a PC and parameters. The imager can easily be integrated into common optical setups thanks to the c-mount mechanical adapter. DLLs for easy integration in most application are provided.
