- I have a night-vision scope that uses a c-mount lens. It is a head-mount unint that is 1X/no magnification, and I would like to get another lens that ideally is 3-5X, but I can’t find any lenses that are quite the same. The video security camera lenses I find all seem to use very small-diameter lenses (6mm or so) where the existing lens uses optics that are about 20mm across. I notice that some lenses are sold for larger image areas (1/2" vs. 1/3"), would the lenses for larger areas be larger-diameter as well?

- The only videocamera lenses I have found that use larger lenses are ones that include features like motorized focus, zoom and electronic irises–and I can’t use any of those things. The existing lens is just a threaded cell with a fixed focal length, that moves up and down in a collar, with the optics as large as possible. Where can I find anything like this? -And I guess I should point out, it’s gotta cost $50 or maybe $75 at most.
