These 'dots' don't seem to be there on my PGL-III-C 400mW, but on my LaserGlow Aries (Which I've used maybe.. 6 times?) I just notced these 'dots' (about the size of the main beam) around the beam. They aren't as visible (relative to the main beam) as they seem in the picture... (hard to explain.. Our eyes get more dynamic range; so at the cost of washing out the main dot, the artifacts around the beam are brightened 'relatively' - kind of like loudness compression in music.)
This is at about 15 feet. The 'main dot' is around 1/4 inch. (The 'sharp', 'scratchy' looking points are nothing -that's just the paint texture on the wall.)
The 'dots' seem to be 'phantoms' or duplicates of the main dot.
I am POSITIVE that the lens is spotless. They aren't THAT bright - it's not like the whole beam is a smudge. And they may have been there before, I may just be noticing this now...
Any idea of what causes this? Could a few 5 minute duty cycles to compare this PGL-III-C to my other PGL-III-C do this?
Or is it something that is just present in some DPSS lasers? I'm out of warranty with LaserGlow on this one, but I'd like to get some folks opinions?
It probably isn't QUITE as marked as it seems in the pictures - not quite as visible. One of them, I'm blocking most of the main dot with my hand to show what's going on there.
I realise I could be just overly perfectionist about my beam quality here.
