Many DMK users both in and out of the Astronomy business have called and written in recently questioning me on the spectral sensitivity and quantum efficiency of The Imaging Source cameras. Well, most if not all of these questions are answered by me pointing the DMK user to what we at The Imaging Source refer to as our "The White Papers". This extensive collection of references include topics on basics optics, CCD electronics, and color interpolation. Although not deemed a DMK users manual, the material covered is extensive and well worth a look for all of The Imaging Source clients.
