my green laser pointer (500mw) has now got a weird hazy blur around the point.
it is really annoying as i have tried cleaning the lens with cotton buds (q tips) and different cleaners but to no avail. if you have any tips on how to get rid of this please help.:thanks:

Use a web hosting site like photobucket and upload it to there. The copy the html link and paste it in here. Or you can use paint and resize it

You should invest in some. Where did you buy the laser from?

You could try a different lens and see if it gets any better. Sometimes getting them out can be a trick though and it may not be worth the trouble. I have a really nice 650/660nm brass device on a keychain with the same problem. I would really like to swap it out because it's definitely damaged, but the lens is recessed and glued. Not even big adjustable pliers will budge it. :undecided:

Click to expand...

Absolute must on getting googles to be safe. on less than 5mW laser take your chances probably OK ,but that's assuming the laser is only putting out 5mW a lot of cheap ones put out up to 10 times that .So with any higher power you can on a direct hit to the eye lose or damage the sight in it in a fraction of a second even of a reflection ,really before you venture future into lasers get some safety googles

I'm no expert so I can't replace the lens myself and don't know how much it would cost to be done at a store, hopefully I don't have to replace the whole laser :/
