50mW 405nm Violet-Blue laserpointer

I'd like to share with you a product that I've come across at the gadget china-store called DealExtreme.
If you want to use this as a pointer at presentations, use white surfaces to point at.. violet laser seems blue then and has much better visibility.. real violet at 405nm dot(when pointed at different than white surfaces) is quite blurry(from about 2meters far).. it's because 405nm is on the edge of visibility for human eyesight..
btw.. the green dot in the video is True Green 20mW also from DX and green shining thing is silly putty sensitive to light

hey can you burn a match with it or just burn some thing?

[Rad86N]

no.. it doesnt have focusing lens, so i cant focus the beam... but i can feel the heat on my hand.. i can burn a match when i shine it through a magnifying glass

Shit music

@Rad86N The lens is fixed with some kind of glue, after carefully removing that glue from the sides of the lens you should be able to set the focus correctly with some innovative thoughts you'll see how.

[bradmann85]

the only great thing about a purple laser is the reaction of certain colors such as a white shirt youll get a blye dot or neon colors and youll get that neon color to glow bright.
