So Today I got my 2nd nubm08 diode. And this one actually had a decent focus. But not good enough. I want it the be a dot from far away (as close a possible at least). And like you can se on the photo it’s not a dot. It’s like the same length as my fingers. So question is. How do I get this focused? It’s a gball so yeah I know it’s not just, to put on a single g2 lens. I already tried putting g2 backwards and then another g2 to actually focus. But that doesn’t work. Any ideas? Beam expander with another lens maybe?
