it is worth a try if you have some laying around. I sure wouldn't put them in my eye afterwards...

Actually, i have several hundred of them. Most of them are concave powers (negative powers ranging from -.50D to -5.00D) however. So at best they would spread the beam not tighten it. If anyone is interested let me know and we can work out something.

is there a way to take out your orignal len and put a new one in and is there a place where you can get new ones that fit like a standard size?
my lens in my 15mW are all scartched up and idont know how it happened but it makes a lot of things around the dot. :'(

Sniper - same thing happened to me - tear apart any cd-rom drive, or dvd-rom drive or burner...you will find TONS of optics inside, and a few lenses that may work for you. Also, there are a few companies that make replcements for pointers - they can run pretty pricey though.

The diode in a cd-drive is low mw red. Burners are where the power is. Cd-burners use relatively low power IR diodes, and the DVD burners use the high power reds, and one low-power IR.
The REALLY neat stuff is the optics inside, as well - some beam splitters, lenses, prisms, etc !

Optics are a BLAST ! You can split the beam into hundreds of points of light (defraction filter) or split the beam into two opposite directions (beam splitter) or super-focus it for maximum burning potential ! Not to mention all the mirrors, and different effect when you combine them with motors, and you have a really nice light show on your hands then !
