Hello, I have purchased a 5w C-mount 808nm IR diode.
I'd like to know what lenses to get to focus it to a pinpoint.
I know what I need, a cylinder lens and then a convex to focus it, but I'd like to get the very best to get the smallest dot for burning for cnc use.
I have a 3,2w O-like laser which only has a focusing lens and the result is not very good, the beam diameter is too big and it wants to set everything on fire, rather then finely etching and cutting.
Please help with specific optics to get.
