4.1. Explanation of Important Parameters
4.1.1. About Spectral Response
QE: Quantum efficiency, which is the ratio of the average number of photoelectrons produced per unit time
to the number of incident photons at a given wavelength.
Sensitivity: The change of the sensor output signal relative to the incident light energy. The commonly
used sensitivity units are V/((W/m2)·s), V/lux·s, e-/((W/m2)·s) or DN/((W/m2)·s).
The spectral response graphs given by different manufacturers are different. Some graphs' ordinate is
relative sensitivity response, and abscissa is wavelength. Some graphs' ordinate is QE, and abscissa is
wavelength.
