Make an optic close focus. Answered
I want to be able to put my night vision monocular in front of my 2x scope on my airsoft.
I need a combination of lenses to put between my scope and the NV to let the scope focus at a couple of inches (instead of 30 feet), and reduce magnification because otherwise I’d just be looking at a tiny part of the phosphor screen heavily magnified.
I know it’s possible because a commercial unit is available, I just don’t know if it’s feasible for a guy like me (doesn't have a degree in optics) to build (I'm thinking no, but I figured I'd ask).
Thanks for any help you can offer.
