SCONTEL: 90% efficiency, single, photon, detector, snspd, sspd

Welcome to SCONTEL's Web-page!

SCONTEL was founded in 2004 and all these years we design, fabricate and sell unique devices based on thin film superconducting nanostructures:

Single photon detectors of visible and infrared wavelengths with picosecond response time, high quantum efficiency and extra low dark counts (SSPD);

Fast and sensitive THz receivers for far and mid - infrared wave range (THz region). 

Upgrade is available for any of your SSPD or THz system. We have been always hard working to expand the range of products with higher & better specs.


Possible range of System's specifications:

System Detection Efficiency: ≥ 85 %  

Timing jitter: ≤ 45 ps  (25 ps on request)

Dark counts rate: ≤ 10 cps  (0.1 cps on request)

Spectral range: 0.5 ÷ 2.5 µm

Dead time: ≤ 15 ns (2 ns on request)

No afterpulsing

Fiber coupling (no misalignment)

Operation in a continuous mode









We congratulate Prof.  G.Goltsman who received the IEEE Award for Continuing and Significant Contributions to Applied Superconductivity at the ISEC in Sorrento, Italy, 2017.


Scontel has participated at the famous exhibition "Laser World of Photonics China". There was the booth with our representative - Aunion Tech Ltd. It was delicious.
