i know hes out of business for bad business practice, my laser does ok, and i think all i need is a simple fix. i have the [SF*501B]*SF501B*445nm*Blue 2-2.4w model. problem im having is the focusing lens, its loose in the ring, and i can hardly ever get it to focus properly. How could i go about fixing this and where could i get one so i can use this thing right, thanks alot guys, you rock!

If it's just loose it the lens housing. Unscrew the lens flip it over there should be a tightening ring with a couple of slots. What I use is s tooth pick to tighten them up. Hope that works :)~~~~~ edit , make sure that no dust gets in torward the diode especially if it open can.

Be careful when you do that^ to not unscrew it or all the lenses may fall out. Happened to me.

And don't get dust in there either, otherwise you may need to clean it with a drill press... :whistle: ;)


That's a joke btw OP, don't do that, I'm poking fun at Craz.
