So, I am new here and on my way with a 1.9W 445nm SH-032. I will have pics up soon and the full specs. Why can't a lens be made to re contour a 445nm beam, to be a circle. Direct the light into a circle. If it is focusable, then It could always be made to be a circle...? Is a G1 or a 3 lens setup better?
