  • Detectors: Guideposts on the Road to Selection |

    The pertinent characteristic to be inspected is the detector’s quantum efficiency as a function of wavelength η(λ) or, alternatively, responsivity σ(λ). Quantum efficiency is a ratio of the number of photogenerated charge carriers per unit time contributing to the output signal to the number of incident photons on the light-sensitive section of the photodetector per unit time.
