UV shortpass filters
Nearly 50 years of experience in coating processes and the new Magnetron Sputtering Technology combined with Japanese discipline, enables such outstanding specifications in all types of filters.
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.
