I need something like this below:
Normal laser I
Direction ^
My laser V
I guess I will need some kind of lens, I was wondering though, normal laser pointers have a diode, with a lens to make the beam focused in a line, or is that not right, do I not need that lens? Well anyways what kind of lens will I need to spread the beam like that? Thanks
