New into lasers
Bought the following green lasers
5mw
20mw
200mw
All the very lo cost to get started
5 and 20mw have very tight beams 2 mm or so
The 200 mw beam is about 4-5 mm
All measured at exit port.
The 200mw is very bright during day for 300 yards or so forever at night.
How does the beam width relate to quality and is there a rating methode for lasers
Thanks All
