Yes, Most semiconductior sensors, such as CCDs,
respond to near-IR. I am
told you can 'see' most remote cotnrol outputs using one, for examplke.
Is Ektachrome IR no longer available? (~35 years since I used any) One should be able to check things by using a
digital camera to view with.
Quite likely. The problem is that it was _me_ who was
setting up this CX
laser scanner module, and I am sure you know by now the sort of cameras I
have :-) Although E6 is the recommended processing, it can work
with a lot of
stuff, even C41 to produce an unmasked negative.
Err, yes... But if I am setting up the optics in a laser printer scanner,
I want to be able to dtect where the beam is (roughly) going and then
tweak the lenses/mirrors to get it where I want it. Not take a photo,
process the bit of film and then tweak the scanner optics, take another
photo, etc. I assume if you use a digital camera for this, you observe
the results on the built-in LCD monitor of the digital camera, you don't
take picutres, upload them to a computerm and then try to analyse them.
