My first laser build!

yeah. i know it sounded like a stupid question.. but with the green laser, the dot is the same at basically any distance. thats why i was wondering.
but now that you've explained that to me. it makes sense.
 





well not exactly but yeah.. green lasers have nice tight beams, but at long distance their ability to burn is very much like an unfocused blu-ray.. it drops off at around the same rate, even tho it is a tight beam!
