guys, what kind of beam specs are you getting and with what sort of lens?
Just found this thread.. I am interested in these red diodes since they are single mode and will have better beam specs.
As far as the DTR lens are concerned.. which lenses give the best divergence and beam?
I have some G2s from him laying around. If no one else has tried them then I might grab one with the 3 glass element and compare them.
3 element is cheap. grab one and see for yourself
In general, longer FL, bigger initial beam with lower divergence
with these diodes, I am almost sure I will choose a 8mm FL 3 element lens for a multidiode setup
