kind of shocked to hear that coming from you andyOriginally Posted by andyf97
i thought you were an optics whizz with all the stuff you have built
as for 20mm round nah that wont happen but oval will.
20mm at what distance ??
best lens option at the moment is the 405g2 lens and prism set

hahaha, yeas well with small beams, it's a general question for what is best, of course telescoping is one option but any others?
*This space intentionally left blank*
I just so happen to be on the market for something like this. What sort of output power are you looking for with a beam that big?
