I figured optics was the bst place for this n00b question... when llooking online at laser pointers, naturally the better ones brag they are "focusable"...
sellers dont really ELABORATE on the amount of "focus"... or, in MY case... the amount of DE-focus, lol
As i wnt to end up with a serviceable Laser IR illuminator... what amount of "focus" is in play here, typically?
as an example? with my LED flashlight, i fooled around with optical lenses, and got a small lens housing mounted onto the end of my UF 501B light... the light itself is nothing special at all... but with the LENS??
sure, up close, at my feet... theres just a super bright SQUARE of light... basically just a focus-ed "emitter"... but, the focus is pretty tight, lol... i can project a square of light onto a house 100 yards or more away...
jus kinda wondering wht amount of "focus" there typically IS with a higher powered laser pointer? I REALIZE you guys are ito focusing it TIGHT, i rather wanna go the OTHER way, naturally... to have a workable IR illuminator...
