Hi alll,
wondered if someone is able to clarify the following - (with respect to chinese glass tube laser) .
Focal length of lens:-
What are the relative pros/cons of longer/shorter focal length?
(i 'assume' longer focal length more suitable for cutting due to less tapering beam and longer focus zone ? )
Lens Coatings :-
some lenses are advertised for sale as uncoated, and suitable for any wavelength. Are these less efficient than lenses coated specifically for 10600?
Thanks for any assistance with this.
