Hey, new here, FIRST POST LOL...
bought one of those laser pens from ebay, i bought one that was $8.98, the one that you see all over the pages ---> 405nm 5mW Blue Laser pointer.
Its a fixed focus and its visible from 1000meters... does that mean when i click it on the beam will stay that diameter and not expand or whatever and become no longer visible until after 1000meters or what? IDK how that all works. I know its some cheap 5mW laser and i know theres ones 100 times better but im a rookie i love lasers =] IM FIRIN' MUH LAZOORRR LOL (help me out)... oh is 405nm like... blue-violet? right?
