Scontel, snspd, single, photon, detector

Welcome to SCONTEL's Web-page!

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

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

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

Upgrades  We always hard work to expand the range of products with higher & better properties. You can upgrade any of your SSPD or THz system.



System specifications:

Quantum Efficiency: ≥ 85 %  

Timing jitter: ≤ 45 ps  (20 ps on request)

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

Spectral range: 0.6 ÷ 2.3 µm

No afterpulsing

Fiber coupling (no misalignment)

Operation in a continuous mode
