colinbm Posted January 11, 2015 Share Posted January 11, 2015 Hi Dave, Good to see some UVIVF from you.Not to rain on your parade, but the B+W486 is not the best choice for this application with the MTE U301 LED 365nm torch.Their transmittance charts are too close together & even overlap. You will need to add something like a GG420 filter to cut the UV entering the camera to less than 400nm.The GG420, will need to be placed on the lens first, then the B+W486 on top, because the GG420 will fluoresce if it is exposed directly to UV light.http://diglloyd.com/...+W-415-420.htmlCheersCol PS, You could also add a UG11 or U340 filter to the MTE U301 LED 365nm torch, to keep it under under 400nm too.Col Link to comment
DaveO Posted January 11, 2015 Author Share Posted January 11, 2015 I'm not using the MTE U301, I have a "McLeish" 365nm titanium torch with a "sundrop" sapphire lens. Dave Link to comment
