Is it possible to mount an iPad on a stand and use it for 40x magnification? There would need to be a working distance of 6" between the camera lens and the surface being viewed. I see these cheap webcams sold for this. It occurs to me these are pure scams of course. Usually made in China and they often claim to have never written OSX drivers. Or you find in the fine print a working distance of only 1 - 2". Seems to me you should just be able to use an iPad and pull off 40x right? Yes? Maybe?
