This person did a good job of explaining it
http://laserpointerforums.com/f44/need-little-input-please-29383.html

Ya so there is this filmy light in a definite circle around the main point, and the point is slightly offcenter in that circle. I dont know why it does this and im pretty sure it happened after i bought the laser from leshoppe.

If you guys have any ideas why it does this please share.

If it looks like what is talked about in the other thread (the one you linked to), the answers would be the same. Post a good picture of the spot. If you want some more specific ideas

Peace,
dave

I have a green module that does this too. It's probably from violating the duty cycle or not having a good enough heatsink. In my particular case, it's something that developed after some use.
