Figure 1: Spectral response curve
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
37.5% approximately between 500 and 700 nm. In view of a fill factor of 60%, the
QE is thus larger than 60% between 500 and 700 nm.
