I was able to focus to a good tight point with my 25mm bi convex, I'm just saying the beam was not square after the 25mm lens, it tapered down to a tiny - which is interesting, the diverging raw output stays square until my lens, but after a lens it focus down to a - bar..........it's interesting to think about how the piece of fiber they used is interacting with the raw output, is it the distance across the width of the cyl fiber that's acting as a lens pair ?
@ Lifetime17 : Have you seen these, I am tempted to get one but 120.00 is a bit high.
