If you have means to read intensity (second port of the light sphere, diode or spectrometer), than, yes. On Mar 15, 2016, at 2:04 PM, Roger Breton wrote:
I have an old visible range Bauch&Lomb monochromator with a 1mm exist slit. If I was to take a picture of the slit with my camera, at some reasonable interval, could that be a crude way to get to my camera's response?
Hypothetically speaking.

Is there a (simple) way to get at a particular camera sensors spectral sensitivities?
Simple, yes. Cheap, not so much. But sacrificing accuracy (still being within most of the practical needs), those can be restored from a shot of CC SG. Problem is, those spectral characteristics depend on temperature and heat distribution across the sensor.
