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.

I should not have even opened my mouth....:whistle:

chipdouglas and andy_con are the ones you should listen to!
I bow to their vast experience...:bowdown:
 
cylindrical lens and prism pairs do exactly the same thing.

but prisms are easy to use/setup
 
thank you for the compliment 532.... but i actually do not have experience. I only know from reading here and at PL.

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.
