About Spectral Response
QE: Quantum efficiency, which is the ratio of the average number of photoelectrons produced per unit time
at a wavelength to the number of incident photons.
Sensitivity: The change of the sensor output signal relative to the incident light energy. The commonly
used sensitivity units are V/((W/m
2
) •s), V/lux •s, e-/((W/m
2
) •s) or DN/ ((W/m
2
) •s).
The spectral response graph 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.
