Single Photon Counting Modules

Single photon counting modules. So-called single photon counting modules are used to count single photons. These photon counters, sold under the brand name COUNT®, offer phenomenally low dark count rates and a high detection efficiency.

Photon Counting Module COUNT<sup>®</sup> Q

COUNT® Q

The COUNT® Q features an integrated InGaAs APD and covers the spectral range from 900 nm to 1600 nm.

COUNT® Q

An absolute highlight is the COUNT® Q. Many of the customers work at wavelengths that silicon does not cover any more. The COUNT® Q features an integrated InGaAs APD and covers the spectral range from 900 nm to 1600 nm. For best performance, the APD is thermoelectrically cooled. Just like the silicon APD-based COUNT® modules the focus during the development of the COUNT® Q has been on high detection efficiency and low dark current.

  • Wavelength range 900 - 1600 nm
  • Detection efficiency: adjustable up to 20%
  • Dark count rate: typ. 1000 cps
  • Single 12 V DC supply operation
  • Air cooling
