hi

good idea this testing....
i too do not know if digital cams (ccd or cmos?) can see uv.
they definitely can see IR (good for testing remotes, night vision).

but i fear that they can't see uv. also any plastic protective covering (on
the ccd chip?) or plastic
lens may shield it....

i have a uv eprom eraser here and a bad webcam at the pc...
i will try ...


looks bad.... the eraser has a uncoated fluorescent tube in it.
so it still produces some visible light...
and on the picture there is not more change on a illuminated white surface
than visible with the eye...
i don't know if ccd/cmos but very cheap and very bad quality..(but lens is
glass i think)



i read once some kinds of paper have chemicals in them which convert uv to
visible.
i read this on a "homebrew co2 laser" page so the light may have to be
intense to see converted white...
they wrote about the very bright white paper...



please check the net with google for ccd and uv... maybe there is
something...


stuff that converts uv to visible is enough out there but you won't get a
clear picture even if you make
some sort of screen....
