None OpticalPhoton - Quantum efficiency of detector?

Hello everybody,

I am quite new in Geant4 and I got a question about the quantum efficiency (QE) of a detector, that should detect optical photons.

The simulated photons are equally distributed over all wavelengths, but at 800nm there is a minimum though the QE at longer wavelength is much smaller.

So the question is, how the QE is interpolated for the values that are not defined? Are 50nm steps too big?

This is how I defined the QE: //950nm, 900nm, 850nm, 800nm, 750nm, 700nm, 650nm, 600 nm, 550 nm, 500 nm

G4double Photocath_EFF[OPT_NUMREAL] = {0.0001, 0.001, 0.013, 0.04, 0.075, 0.03, 0,01, 0.0};

Thank you very much, Denis
