Default Need help: 532nm Lens Problem

I have a module out of a 532nm pen I bought that meters at 45-48mw but has a problem with the lens.

Bad flair and feathering.

Looks like a Galaxy pic.

Here is also pic of the module and the lens barrel.

Looking thru a Jewelers loup it looks like metal flake imbedded in the glass
and I tried cleaning but the specks are below the surface of the lens.

Any one have a busted 532nm module you would like to part with the lens barrel assembly???

Its a shame since this was a 5mw pen pushing almost 50mw.

Default Re: Need help: 532nm Lens Problem

I would send you a spare lens from one of mine- but they are all like that. Cheap lenses, can't expect much! I have gotten one module (ever) that had a nice dot. The rest are just crappy, spread out, "galaxy" looking dots. Hope you didn't pay a lot for it! If you want, you could just buy a 5$ "5mW" module off eBay and steal the lens from that.
