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.

Cheers

PS, You could also add a UG11 or U340 filter to the MTE U301 LED 365nm torch, to keep it under under 400nm too.

I'm not using the MTE U301, I have a "McLeish" 365nm titanium torch with a "sundrop" sapphire lens.
