Today I finally got my wood's glass filters. As people here with 365nm led experience know the led's themselves emit a small amount of whitish light. This tends to obscure some of the fluorescing effect of the led. Well after going to a local stained glass place and having them cut out a glass circle from the 2"x2" piece, I have to say it vastly improves the quality of the UV light output.
From my driver's license to the colored stripes glowing on various denominations of dollar bills, the contrast is greatly improved. For anyone with a 365nm UV light I highly recommend getting a wood's glass filter made.
