Sub-Electron Read Noise & Low Dark Current

Industry-leading low-light imaging capability

  • Read noise <0.2 electron r.m.s. at 25C

  • Dark current lower than 0.1 electron/pixel/sec at 25C

  • Small pixel size and high resolution

  • Photon-counting without electron multiplication, high voltage, or dead-time

Reliable Photon Counting
& Photon Number Resolving

  • Accurate photon-counting

  • Reliable photon number resolving with more than 99% accuracy (less than 1% Bit-Error-Rate)

  • Large photon-counting range up to 100s and 1000s of photoelectrons

High Quantum Efficiency

  • Advanced backside illuminated (BSI) technology

  • >80% of QE at 500nm wavelength

  • Excellent pixel isolation and color cross-talk
