ID281 Superconducting Nanowire

Single-photon detector with 80% quantum efficiency and fastest electronics

  • Detection range: 400-2500 nm
  • 80% quantum efficiency
  • Jitter: 50 ps (FWHM)
  • Closed-cycle cryostat

IDQ’s ID281 series detection system consists of a superconducting nanowire detector combined with high-performance electronics and reliable cryogenic system. The system operates at 0.8 K and offers impressive performance such as 80% quantum efficiency, count rate up to 15 MHz, dark counts <100 Hz, jitter below 50 ps (FWHM) and no afterpulsing.

The complete system is plug and play and includes: cryocooler, stable and adjustable bias current sources, cryogenic amplification stage, discriminators and counters. It comes with the best-in-class control and timing electronics: 1 GHz counters, 20 ps time resolution and fast data transfer rate (100 Mcps).

Our superconducting nanowire single-photon detectors can also be integrated in your own cryogenic system: the ID281 comes with everything that is necessary to install it in your own cryostat; including electronics, software, feed-throughs, cryogenic cables and connectors.
