UV Led and Diazo

This image was made using Diazo paper and a white LED attached to my FET mechanism. This exposure time was for 10 hours and placed directly onto the paper.



I found this UV LED "conterfeit money detector" at the dollar store. This key chain with one LED retails for $1.25 +tax which is quite the steal compared to the $3.00 some electronic stores were charging... not to mention many retail stores would have to special order them so add on the week for shipping.



Although the white LEDs were working, the images were still quite ambiguous because the LEDs were not emitting enough UV light to expose the Diazo paper. I decided to try the UV LED in it's place to capture clearer images and reduce exposure time. The results were very successful.
