Design of Metal-Dielectric Filters in Transmitted Ultraviolet Light

Abstract

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