So I will be making a 2 W labby using a 445nm diode and would like to point at, say 100 meters without the dot being extremely big. Sorry but I have no experience with correction optics and generally with lenses etc. Thanks in advance.

P.S also, i apologize if this has been discussed before.

prism pairs seem the best way on the hobby level. somebody over on pl sells them. i think andycon does too. also look at wannaburns stuff. he made something similar with prism pairs.

cylindrical lens and prism pairs do exactly the same thing.

but prisms are easy to use/setup

They have about 30% loss through them if I remember correctly. Any prisms work but Some have lower losses than others. "Anamorphic" describes the application rather than the optic itself.
