Abstract

"SENSOR óTICO FLUORESCENTE DE ELEVADO DESEMPENHO". A presente invenção refere-se a um dispositivo sensor ótico para determinar a presença, ou concentração, de um analito, contém uma guia de onda (103) disposta sobre uma fonte de luz (101) de um substrato (100) e separado por um defletor interno (104), em que a guia de onda tem uma espessura correspondente a um ponto de emissão de campo distante de fonte de luz, conforme determinado por um defletor de proteção de luz entre a fonte de luz e o defletor de luz.
