Sub-Electron Read Noise & Low Dark Current

Gigajot offers industry-leading low-light imaging capability

  • read noise <0.2 electron r.m.s. at 25C
  • Dark current lower than 0.002 electron/pixel/sec at 10C
  • Small pixel size and high resolution
  • Photon-counting without electron multiplication, high voltage, or dead-time

Reliable Photon Counting & Photon Number Resolution

  • 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
