UV Longpass Filters

figure UV Longpass Filters
Our UV longpass filters are designed to have a very sharp transition between the reflect and pass bands while maintaining very high transmission at UV pass bands. The spectral transmission properties are uniform over the entire aperture of the filters.
UV longpass filters can be combined with our UV shortpass filters in pairs to create a variety of transmission bands.
