Note: Quantum efficiency (QE) can be calculated by dividing the responsivity by the area of the sensor's element and multiplying the resulting ratio by the energy per photon
in electron volts (eV).
The dark current is typically 0.2pA at 25^°C and varies as function of temperature. The dark current will contribute dark-signal charges
and these charges will increase linearly with integration time. The dark signal and the photo generated signal combined result in the
total signal charge.
