Product features:

The ASAHI Spectra UV short pass filters have very steep flanks between the reflection and passband regions, while maintaining very high transmittance in the UV transmission range. The spectral transmission properties are constant over the entire passband of the filters.

UV shortpass filters can be combined in pairs with UV long pass filters to produce a variety of transmission bands.
