OK, I have a conformal coating question being debated internally related to the wavelength of light used for black light inspection of conformal coating. Fluorescent lights tend to emit more around 365 nm, which is where you get the most fluorescence from the dye. I would like to use some of the new LED black lights, lower power, longer life, much brighter, but they emit in the 395-410 nm wavelength. Seems to illumine the coating just as well, but am getting pushback from some areas of the company. So, here is my question: Are there coating features or defects which you can see at 365 nm, which you cannot see at 395-410 nm? Doug Pauls Principal Materials and Process Engineer Rockwell Collins
