Figure 1
shows the spectral response characteristic. The
curve is measured directly on the pixels. It includes effects of
non-sensitive areas in the pixel, e.g. interconnection lines. The
sensor is light sensitive between 400 and 1000 nm. The peak
QE * FF is 15% approximately between 500 and 700 nm.
