Photon Force technologies are accelerating progress in multiple areas including photonics, quantum optics and research in other scientific and engineering fields.
The PF32 camera range with Time-Tagging SPAD Arrays
PF32 cameras have a 32×32 Time-Correlated Single-Photon Counting (TCSPC) pixel array, with fully digital photon counting and time stamping – meaning no analogue readout noise.
In-pixel timing electronics enable the time-tagging of incoming photons to an accuracy of 55ps. An incredible throughput of up to half a billion timestamps per second can be captured, with an IRF of down to 200ps FWHM.
What is Photon Force sensor technology used for?
When it comes to use of our photon counting technology, the applications are numerous and just keep growing! To date, our sensor technology has been used in areas including:
Diffuse Correlation Spectroscopy
Imaging Through Scattering Media

The video below is an excerpt from the paper ‘A high speed multifocal multiphoton fluorescence lifetime imaging microscope for live-cell FRET imaging’ by Simon P. Poland et al, where the PF32 SPAD array camera was used in conjunction with a two dimensional array of ultrafast beams – the multibeam confocal architecture. This parallelism of excitation and detection allowed FLIM FRET imaging to be performed at unprecedented speeds.
The image on the left of the video shows intensity, the middle image depicts lifetime and the right-hand image combines both intensity and lifetime.
