I was wondering if you could help me with a Gen 2+ device I have recently acquired.
I bought an OPTEX M911A image intensifier on ebay in the hope of being able to use it as hand held monocular, it came with lens adapter at both ends that fits a canon bayonet mount that I am yet to identify. The device itself was built on license from Litton, and is identical to the Litton M911A night vision Monocular besides the branding.
I'm having real difficulty finding any attachments to convert this into what is essentially a Litton M911A night vision monocular, I can't find any objective lenses or adapters in stock using the search terms I'm using however I've taken a gamble on using a PVS-5 Eye piece to replace the lens adapter on the viewing end, due to them using the same housing as the M911A, the objective lens will not fit.
I've not got any calipers to hand but the objective end is about 37mm threading and 10mm deep. Left is Unit, Right is Adapter to camera Lens
I know Litton originally sold a C Mount adapter for the objective end of the M911A, but is there some other way I can adapt it down to fit C-mount or any other type of lens that is still actually sold.
If you need any more information please let me know, I've searched high and low for any useful information I can find on the Litton units but I must not be looking hard enough, any help would be appreciated.
