Works fine, no problems with focus and fits well with threads, reduces huge beam divergence especially for my Class 4 638nm ones, although there are power losses during the conversion, my 638nm diode Oclaro HL63193MG from 520mW to ~420mW although I cannot confirm exactly, losses are between 20% and 10% this will also depend on the divergence. Beam starts very thick but it gets smaller and smaller, during the thickness beam loses a bit of visibility but after some meters divergence becomes more beautiful and decent.
