I've been looking into using an ir camera but my main problem is finding a screen small enough to fit within the scope.As for building it yourself, you could always cannabilize either night vision capable camcorders or you could try finding surplus Gen1 night vision gear online to use.
Just off preliminary searches, I haven't found a screen small enough to fit into a scope body.You could locate the display screen towards the front of the scope body and use lensing at the eyepiece to compensate for the distance between the screen and your eye (if that makes sense).... That would almost triple your screen area.
What kind of range are you looking for on the scope's functional IR range?
It's not a lens that's sensitive to IR light, it's a type of vacuum tube called a photomultiplier or image converter (it essentially amplifies the photons of light coming into it, and is sensitive to the IR range). The type used on the first US Sniperscope T120 system was made by RCA originally for TV cameras and came to be known as Generation 0. That was replaced by the Generation 1 image intensifier tubes used in the Vietnam-era Starlight scope.. Here's an article that explains how tube-based night vision works and how the generations have developed:I am not exactly sure how IR night vision works. Is there a certain kind of lens that only sees IR light?
I think that they toy NVGs might be a good bet since their displays seems to be fairly small, around the size scope. Even if it's a little too large for the very end, I imagine that it can fit at least to end of the second tube and you could always add a magnifier to the very end to enlarge the image.Just off preliminary searches, I haven't found a screen small enough to fit into a scope body.
For range, toy nvgs can get around 20 meters and I was thinking ideally I would be able to get at least that.
Will do, thank you for the help!I actually just found my pair of night vision goggles, let me know if you have any questions about size, quality, range, etc, or if you'd like me to send them to you. I still stand by my earlier statement, that these are probably your best bet for replicating this device
