Abstract

The article presents polymer optical fibre with sensitive luminescence cladding used for ultraviolet detection. The construction of polymethyl metacrylate (PMMA) fibre coated by organic dye doped polyurethane film is presented. The Tinopal (fluorescent optical brightener) incorporated into the polyurethane coating was used as UV indicator. The chosen dye allowed to direct UV-A detection with luminescence emission in visible range. The construction and fabrication process of UV sensitive polymer fibre is shown. The experimentally obtained characteristic using Nd: YAG (355nm) is presented. The high relative sensitivity up to 0.27mW^-1 was obtained. It has been pointed potential applications of fabricated senor.
