Notes:

1. Fill factor, quantum efficiency, and responsivity are related by the equation R = (qel/hc).QE.FF.A, where qe is the

charge of an electron and hc/l is the energy of a photon at a given wavelength. Responsivity is therefore given per

pixel.

2. At wavelength of 575 nm (yellow-green) and with no window.

3. Measured at 50% Vsat with an incandescent tungsten lamp filtered with an Schott KG-1 heat-absorbing filter.

4. Saturation charge specified for a video output bias of 4.5 volts.

5. Max dark leakage £ 1.5 x average dark leakage measured with an integration period of 500 ms at 25oC.

6. From 250-1000 nm, responsivity ³ 20% of its peak value.
