hi everyone
can someone please tell me if i have this right
the bigger the optic(diameter), the tighter the beam ?

No, it is possible to have a small optic with a tighter beam than a large one - the maker should state the angle of beam the optic gives in their data for it.
 
For collimating optics, the optic size will also play a factor because the source of light is not a point source. (Some what similar to what happens with reflectors.)
