i'm brand new to laser pointers and have gotten into them as a result of another project i am working on. i am using simple laser pointers to mark a spot so i can visually see movement of the target (on video). i am trying to get a smaller dot at ~ 50'. the ones that i am using are from a 'laser parking system' that they sell at Lowes. i have taken them apart to better focus them, but the dot is still ~3/8" at that distance. i have been looking at buying ones that have adjustable focus, but i'm not sure what the best that i can hope for would be.
any help would be much appreciated.
thanks
