ID100 Visible Single-Photon Detector

High timing resolution and low dark count rate

This product is no longer available for purchase. Contact us if you need more information.

  • Free-running
  • 35% quantum efficiency
  • Low dark count rate <7 Hz
  • 40 ps timing resolution
ID Quantique’s ID100 series offers compact and affordable single-photon counting modules with best-in-class timing resolution (for TCSPC application) and low dead time.

Based on a reliable silicon avalanche photodiode sensitive in the visible spectral range, the module is able to detect weak optical signals down to the single photon level.

With a timing resolution of only 40 ps and a dead time of 45 ns, this module outperforms existing commercial detectors in all applications requiring single photon detection with high timing accuracy. The ID100 has excellent timing stability up to count rates of 20 MHz.

The ID101 series targets OEM applications by offering the world’s smallest photon counter for the visible range. It consists of a standard TO5 – 8pin optoelectronic package, a CMOS chip combining a 50 um diameter single photon APD and a fast quenching electronics, mounted on a thermoelectric cooler.

Versions with optical fiber coupling – including singlemode, multimode 50 um and multimode 100 um – are available.
