However, white paper, especially that very white stuff, has chemicals in it to make it fluoresce blue easily to appear more white. Therefore you're looking at a bright blue dot from fluorescence.

is that glow in the dark paint? thats awesome! cant a green do the same thing tho?Razako said:For those who don't have a blue ray this is what people mean by fluorescence.

Fluorescence is the only way I can get my camera to pick up a dot from a blu-ray laser! Otherwise all I got is a faint spec. So yes, I cheated and pointed the blu-ray at the box the assembly came in!pseudonomen137 said:Styro, that ain't a blu-ray dot. That's a blue dot . A blu-ray dot would be much more faint than a red.

The blu-ray dot isn't much brighter than a good 5mW red, but the blu-ray beam in a dark room is WAY brighter than a 5mW red. It's even brighter than my DIY reds (easily >100mW) I don't know why the blu-ray beam is so bright, one weird thing you will notice when looking at the blu-ray beam at night is that you will see no color in the beam. Unlike the green and red laser beams, you can't see any color in the blu-ray beam, just a line of gray.
