Take a quick look at this
There is a full manual here also..
Its a proper Thermal Imaging unit - not just night vision/predator cam - and I've found a 'cheap' one (compared to what it originally sold for that is) and I'm particularly interested if I could mate this up with a 16mm, 35mm or video camera ... (I'm talking cine and not stills but the mod would be the same in either case) - Looking at page 10 of the manual I cant see any ground glass where the image would be focused, would I instead simply put a short focal length lens on a camera and poke it up near the finder ? (sort of approximating the camera to a viewers eye) ...
I'm reasonably capable of machining it if need be.
Anybody with experience in this sort of thing - optics/video-taps/mods/odd-ball projects appreciated
