about ayear ago ı started to making beam expenders but all of then turn out to be total garbage because they significantly drop the total ligth but today ı made a new one from 70 mm porro prism binoculars and this is the best beam expander that ı did so far because it doesnt realy drop the output but its extremly ugly and very large

divergence on this setup is suprisingly low
beam at output is 70mm beam at 400m away is 100mm
ı hope its not illegal to own laser with extremly tigth beam
