I'm wondering if a product exists out there that is basically like a wide divergence or narrow throw flashlight. The wavelength would need to be in the longwave UV range (315nm-405nm) and have considerable power and throw. 350nm wavelength would be ideal because I know it will work... I have a handheld 350nm inslection wand but it is too dim and diffuse to inspect something large areas at longer distances.
The application is for inspection of large areas for flourescent materials and a collimated laser dot would simply be too small to use... it would take forever to inspect any large area with a small dot. At the same time, the surface I will be looking at is ~50-100 feet away so the throw must not be too wide. Maybe 3-5 degrees of divergence (about 40-80mrad) would be OK.
I'm thinking the more power the better (the inspection room won't have to be too dark to inspect) but I also don't want to get cancer or anything. :can:
Do they make longwave (~350nm) flashlights, spotlights, torches, or laser emitters that have a long throw? Can one be easily made?
