A filter, by definition, reduces the amount of light reaching the sensor, by filtering out certain photons, e.g based on color (wavelength) or polarization. None of that helps to give you "night vision", where reducing the number of photons reaching the sensor is the very last thing you want. There is no magic passive "filter" that instead amplifies the light reaching the sensor. Photons have energy, so to create extra photons you would need something powered, not just some dumb piece of coated glass. |
