Paper Abstract

The fluorescence detector, a component of the AUGER project, is designed to observe fluorescent light generated in interactions of high energy cosmic rays with nitrogen atoms in the Earth's atmosphere. This article present several designs of optical filters transmitting in the range 300 nm- 420 nm, where the fluorescent light is emitted. Two approaches are proposed: a system of thin dielectric layers and a combination of suitable glass plate. Quality of different filters is determined according to the value of transmittance in the required wavelength range, the shape of the transmittance curve at the edge of the transmitting window, long-term stability as well as feasibility and cost of their mass production. Selected types of filters were prepared, their parameters measured and compared with predicted values.
