We'd like to image extremely low-intensity light imaged on a card in a dark optical research laboratory environment. High resolution or magnification is not necessary but it would be nice to be able to focus closer than 1m. Do these respond to blue light (405nm wavelength) or are they mostly biased toward IR?

Hi
NV is defintely shifted to the red for spectral reponse and few units will have a close focus of 1 meter. For your application, A CCD sensore may be more appropriate, though we don't have the experience for this application or access to the spectral information to make a recommendation. Sorry, this is out of our line of expertise. _________________ ----------------------
