Would I be right in thinking that viewing the beam alone isn't damaging, but looking at the lens is? Presumably then, unintended viewing could be limited if not eliminated by shining it through a tube?

    No one should be viewing any of it without goggles. It will damage your vision after just a few seconds of indirect exposure, direct exposure (pointing it at your eyes) will blind you.

    Glad to know I was quite wrong. Thank you for potentially saving my vision.

    Not knowing much about lasers myself obviously, is a welding helmet be sufficient protection from indirect exposure?
