The spectral sensitivity is typically expressed as a QE Curve, in which the probability to detect a photon of a particular wavelength is expressed as a percentage.So for example if one in every 10 photons is detected this is expressed as a QE of 10%. The curve for a typical CCD is shown in the diagram on the below:
sensitivity senÂ·siÂ·tivÂ·iÂ·ty (sÄn'sÄ­-tÄ­v'Ä­-tÄ) n. The quality or condition of being sensitive. The capacity of an organ or organism to respond to a stimulus. The proportion of individuals in a population that will be correctly identified when administered a test designed to detect a particular disease, calculated as the number of true positive results divided by the number of true positive and false negative results.
