I am working on UV flourescence photography, and one of the bigger concerns is that most UV sources spill over into the visible range (>380nm). I can control some of this by using filters on the source, but I would like to add a filter on the camera that would effectively eliminate the remaining spillover. I am looking for a 62mm UV filter that provides almost total blocking below 400nm. Most don't show an absorption spectrum, so it is not clear how much transmission there is in the 380-400nm range.
If any readers know of such a filter, with specs, i would be very grateful.

A 400nm UV filter should cut out light below 400nm which would cut out 380nm wavelength. I think 400nm is considered as the limit of visible range. However, if you shoot digital you shouldn't care as imaging sensors are not sensitive to UV light. They are sensitive to IR which requires a built in filter to cut out the IR.

I don't think you need a filter at all. The digital camera is not sensitive to UV. The flourescence material absorbs UV light but emit visible light of significantly longer wavelength.
