FS:Sinner10x - Beam Expander And Attachment

[Alaskan]

......Since all the beam expanders has a lot of power loss, I do not suggest the use of three elements glass lenses, unless You do not care a noticeable power loss or prefer a very focused small line instead a big fat line ...

Not to divert the thread on this subject, but I built a single lens beam expander which does not have as much loss as a conventional BE using a single PCX lens coupled with a defocused G2 or similar lens with it. Still two total lenses, but better than a three lens setup using a Galilean type expander (when you also count the lens in your laser). You could also take the raw ouput of your laser diode and use a single PCX lens to do the same thing, I just like using a defocused G2 because it's easy to control the spot size that way allowing the use of just about any PCX lens FL.

If you want to post regarding the design please do so in the above thread.

I'm definitely down for one
