Not really. If you want to take a hack at it, the first thing you'll need is the transmittance curves of your (presumably Bayer) color filter. Then,if you're lucky, there's an NIR wavelength at which at least two color filters have some responsivity, and those color filters have no overlap in the visible range. In such a case, you could play with sum and ...


The Bayer filter passbands are designed to be make the sensor have a reasonable match to the human eye, while not costing too much. They're fairly leaky even in the visible part of their stop band, and pretty much uncontrolled in the IR. To increase their blocking in the IR a more expensive recipe in a thicker layer would be needed. The thicker layer isn't ...
