Paper Abstract

A type of narrowband interference filters for use in the UV-B-spectral region has been developed. The filter is marked by an extremely narrow bandwidth of about 2 nm, good rejection on both sides of the pass band, and high peak transmission. Care has been taken on the stability of the spectral characteristics of the interference filters against changes of environmental conditions by using only stable oxide thin-film materials. The filter performance achieved allows its use for the development of sensitive and specific instrumentation for environmental, climate, and meteorological research.
