Applications

Confocal microscopy: SPAD arrays increase light collection and enable innovation in the field of laser-scanning confocal microscopy. This innovation finally leads to a sharper and brighter image with functional information about the underlying molecular function, interactions and environment. SPAD arrays provide the following advantages in confocal microscopy:



  • Achieve super-resolution with a standard confocal microscope

  • Increase light collection

  • Increase imaging speed

  • Reduce background noise.


Quantum information: Temporal photon correlations and photon number resolving (PNR) are fundamental to probing the quantum properties of light. SPAD arrays have an extremely low crosstalk and thus enable reliable measurements of second and third order photon correlations, as well as quantum random number generation for unbreakable encryption. SPAD arrays provide the following advantages in quantum information:



  • Simplify setup with single-chip multi-channel detector

  • Increase data rate with detector parallelization

  • Photon number resolving (PNR) detection.


Fluorescence lifetime imaging microscopy (FLIM): SPAD cameras increase the overall photon throughput compared to scanned detection systems from the typical 10 Mcounts per second to 26 Gcounts per second. SPAD cameras provide the following advantages in FLIM:



  • Simplify FLIM setup

  • Increase FLIM frame rate.


High-speed imaging: SPAD cameras enable high frame rates with global shutter at zero readout noise. SPAD cameras provide the following advantages in high-speed imaging:



  • Image fast phenomena in low light conditions

  • Image light-in-flight.
