Hi Thomas,
My posting was meant to open a discussion in order to avoid making films or
other transparencies.
Of course, multiple UV LEDs will do the job, with suitable summing optics.
Unfortunately I live in Romania, where is very hard to find UV leds or
lasers. Optics, cheap, to allow experimenting, NO way.
E-bay is there, but no PalPay for Romania, so.....
The medium monthly salary here is $150, so everything is expensive for us.
We have to go straight to the target, no funds for experimenting.
What remains for me is to initiate a discussion hoping someone there, with
more possibilities....
