well I'm not happy !! I bought a 2.4w 445nm in the 501b host just 30 days ago. Just the other day I decided to try to clean the lens in hopes in improving the terrible spot the laser was producing but can't ! I went and bought white distilled vinegar (read that was best to use) and didn't get any improvement. Next I got out a magnifying glass and began to inspect the lens further. I found a spot "in" the lens that seems to be a defect and can't be cleaned only replaced. I'm now left with shelling out another $40 on a new lens on a laser that has been used maybe 10 times. I wouldn't buy another one of these that's for sure.
A G9 lens is all I know. I got some info on another thread about lens's and what one's I can use. No where can I find the G9 but been told the G1 or G2 will be about the same. Someone even suggested I try a 3 element lens because they provide a better beam. I'm very new to the high power lasers and 445nm for sure and read every day trying to know enough.Hey
What lens did it use. Size, model...?
