Optical interference filter 390BP20 15MM uv absorption
This is a very high performing near UV filter, ideal for exciting many fluorescent dyes. It also can be used to collect the emission of UVB excited fluorescence.
The filter is made using a combination of dielectric materials, as well as absorbing glasses, so has very high transmission, for this wavelength region.
The filter specifications follow: CWL 390 +-4 nm, Half Bandwidth of 20 +-4 nm, Peak Transmission >50%, Out of band transmission average .001%. size 15 mm dia, mounted in an anodized Al holder.
For a most comprehensive assortment of filter solutions, follow the link at my store, under "Technical Data" to the Omega 'Build A Filter' tool. Millions of potential matches are available. Prices are very reasonable if you indicate "cosmetic seconds acceptable".
