LASER COMPONENTS COUNT® Single Photon Counting Modules

LASER COMPONENTS’ COUNT® series of Single Photon Counting odules M has been developed to offer a unique combination of high quantum efficiency, wide dynamic range and ease of use for photon counting applications. Combining LASER COMPONENTS’ ultra-low-noise VLoK silicon avalanche photodiode with specially developed quenching and signal rocessing p s p electronics, the COUNT® Series offers everything needed for ingle hoton d etection from 350 – 1000 nm. Incoming photons generate orresponding c electrical pulses which may be conveniently read out at the TTL output. The gating function allows...

Applications ▪▪ Single Molecule Analysis Dynamic Single Molecule (DSM) analysis reveals very complex details of the binding kinetics, dynamic and functional mechanistic information, such as underlying dynamic processes for DNA-protein interaction and protein conformational changes. ▪▪ Confocal Microscopy Use of point illumination and a pinhole in an optically conjugate plane in front of the detector in order to eliminate out-of-focus signal. ▪▪ Fluorescence Correlation Spectroscopy Observation of fluorescence emitted from a very small space in solution containing only a very small number of...

The allrounder: With high etection d In time-correlated single photon counting (TCSPC), single photons are counted range and very low dark count rates and the time of detection is etermined d the COUNT® module is used in based on a reference signal. This a pplications including spectroscopy, method is a statistical counting method. quantum optics, LIDAR and particle sizing.
