Abstract
A metal-dielectric narrow-band filter for a wavelength of 270 nm is calculated within the framework of the conductive surface model for characterization of the properties of thin metal films. It is demonstrated that inclusion of four thin molybdenum films to the dielectric structure ensures effective transmission cut-off at <1.5 % in the visible range of the spectrum with the maximum transmittance more than 50 % for the identified wavelength and the spectral width of the filter <5 nm.
