As far as that "X" pattern is concerned, I'm not as knowledgeable as some on beam patterns. It could just be dirty.
To clean, don't take it apart. Use some canned air to blow air (not by mouth) down on the lens. If more cleaning is needed use rubbing alcohol on a Q-tip, or other small applicator.
It could be reflections from the cavity. I don't have mine right now, but I want to look at it just so see if I have anything similar going on. I'll edit this post once I get home.
Did you clean both sides of the lens? You should try the q tip with a tiny bit of alcohol on the diode face too, this can cause splashing also. Just make sure not to push down too hard on the diode face when cleaning it, you dont need to apply a lot of pressure when doing this
Sounds like that did the trick & your problem is solved
Sorry bro... I got my lasers out last night and forgot to take the picture for you. Dang destracting shiny lights!
I'm assuming you're talking about a 'halo', so to speak, around the area where your dot is pointed. I was thinking that it might have been caused by reflections from the cylinder, just after the final lens. I don't know deep your lens is mounted from the front face of your laser.
It could also still be dirty from the other side of the lens, but if you've never taken it apart it is highly unlikely. If anything, I would leave it together if it has always been kept intact.
could be micro scratches on the lens from the q-tip. i have the same thing goin on so i got the lenspen micro comin in the mail saturday. I absolutely HATE dot splash. It drives me up the fricken wall.
