Confocal microscopy

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

Why SPAD arrays?
  • Achieve super-resolution with a standard confocal microscope
  • Increase light collection
  • Increase imaging speed
  • Reduce background noise

Applications
  • Image scanning microscopy (ISM)
  • Quantum ISM (Q-ISM)
  • Super-resolution optical fluctuation ISM (SOFI-ISM)
  • Fluorescence lifetime imaging (FLIM)
  • Foerster resonance energy transfer (FRET)
  • Fluorescence correlation spectroscopy (FCS)
  • Stimulated emission depletion microscopy (STED)

Quantum information

Temporal photon correlations and photon number resolving (PNR) are fundamental to probing the quantum properties of light. Our detector has an extremely low crosstalk and thus enables reliable measurements of second and third order photon correlations, as well as quantum random number generation for unbreakable encryption.

Why SPAD arrays?
  • Simplify setup with single-chip multi-channel detector
  • Increase data rate with detector parallelization
  • Photon number resolving (PNR) detection
