Notes:

(1) Fill factor, quantum efficiency, and responsivity are related by the equation R =

photon at a given wavelength.

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

(3) Measured at 50% Vsat with incandescent tungsten lamp filtered with a Schott KG-1

(4) Max dark leakage

≤ 1.5 x average dark leakage measured with an integration period

of 500 ms at 25

(5) From 250-1000 nm, responsivity

≥ 20% of its peak value.
