Collimating and Refocusing reflectors

[Chief_Wiggum]

Can someone please tell me the difference between the two? I'm interested in trying out some of the Carley 0.75" reflectors, but would like to understand the differences between them. Thanks!

Ive been wondering about that too. I *think* collimating is fixed focus, whereas refocusing ones let you adjust the beam like M@glites do.

i think mags are parabolic.
