Not going to happen!

Photons of different wavelength are absorbed and converted at different depth in silicon sensors. Blue photons mostly convert at the surface, while red go much deeper into the sensor. The pixel electronics of a regular cmos image sensor however will only collect the resulting electrons in a certain region at the surface. If an electron is generated somewhere else, it will recombine and be 'lost', not contributing to the signal.

Depending on the sensor, at 1000nm only <10% of the photons will result in electrons that are captured by the pixel electronics. The sensor does not give you any signal any more.

Why? Silicon has a band gap of 1.12eV - photons with lower energy will not interact. This corresponds to ~1100nm - you will need sensors with different materials

Thanks, this was very helpful(and interesting) for the IR part of the question.
