So recently i just bought this laser:
660nm 200mW Red Laser Diode Module DIY Lab Astronomy | eBay
I dont have any "real" lithium batteries to power it, so at the moment im using a set of D batteries(brand new AA and AAA batteries didnt do it). it can pop a balloon in about 10-20 seconds at about 15 feet, however cannot light a black match anywhere near up close. It wont sting bare skin, even after around 30 seconds or so, and it turns to a HUGE (~10 feet?) red dot at around half a mile, with a beam barely visible at night. Right then, i looked into the module(while its off) and noticed that it didnt come with any lens -_-
my 50 mw from led shop pops it in about the same amount of time up close, but from afar (like 10 feet) it has no hope..
So now my question is:
What batteries should i use for this?
and
What is a good set of lens i can use?
