QD800-pQ
Single Photon Detection Module
Description
QD800-pQ series of Single Photon Counting Modules offers a
unique combination of low dark count rates and very low jitter in
a miniature package. The special mechanical design allows a
flexible combination with existing systems in the laboratory.
Incoming photons generate corresponding electrical pulses
which may be conveniently read out at the digital output.
Features
Low dark rates
Very low jitter
High detection efficiency (400 nm to 1000 nm)
digital output pulse (0,4V) at SMA connector
Single 5 V DC supply operation
42x42 mm (wxh) package suitable with „multicube"
Applications
Quantum optics, quantum cryptography
Fiber optics characterization
Time Correlated Single Photon Counting (TCSPC)
Fluorescence, fluorescence life time spectroscopy, Raman spectroscopy
Single photon source characterization
Eye-safe laser ranging (lidar)
Time-of-flight measurements (ranging)
Time-resolved fluorescence spectroscopy
Fluorescence Lifetime Imaging (FLIM)
Fluorescence Correlation Spectroscopy (FCS)
Fluorescence Lifetime Correlation Spectroscopy (FLCS)
Single molecule spectroscopy
Optical Time Domain Reflectometry (OTDR)
Optical tomography

1) Dark count rate at 5% photon detection probability 3 (830 nm, ambient temperature of 22°C).
2) If the temperature reaches the set point, T-OK goes high.
3) The voltage of the analog out Temp represents the temperature of the SPAD. See diagram below.
