Spectral response (valid for about 380-850nm) - (c) Dr G Verhoeven:
[Please note that the valid range of the results is about 380-850nm only, since outside that range, the equipment used was not suitable and the measurement errors too high.]
It gets quite obvious, that this camera has some useful UV response in the red channel and only minimal response in the green and blue channels.
For near IR (NIR) however it shows quite high response in the red but also green (>750nm) and blue (>780nm) channels.
