Abstract
In order to reduce the number of thin-films necessary to construe an interference band-pass filter for exclusive transmission of light in the UVA range the filter edge towards smaller wavelengths in the spectral characteristic is realized by the absorption edge of the material of one of the thin-films of a thin-film interference filter which filter produces the band-pass filter edge directed towards higher wavelengths.
