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

No afterpulsing

Fiber coupling (no misalignment)

Operation in a continuous mode









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.
