Subject: Re: [Homebrew_PCBs] buying LED's for a exposure box

Can a digital video camera see UV LEDs?
I know it can see IR, but i dunno about UV. It may be useful to judge
differences and illumination pattern if it can.

If it can't maybe one can build a meter with a suitable receiver to
select LEDs, or maybe it is as simple as putting a sensitized board
right up against the array and making a borderline short exposure to
weed out any extra strong or extra weak LEDs.

I am glad i do not need photoprocess for the boards i want to make.
