Abstract

"CABEçA óTICA DE FOCALIZAçãO MINIATURIZADA, EM PARTICULAR PARA ENDOSCóPIO". A invenção se refere a uma cabeça ótica para equipar a extremidade distal de um feixe de fibra ótica flexível (2), designada para ser impelida em contato com uma superfície de análise, e compreendendo meios óticos (3) para focalizar um sinal de excitação em um assim chamado ponto focal de excitação localizado à uma profundidade específica abaixo da superfície de análise, e para amostragem de um sinal retro-difundido pelo ponto focal de excitação que é carregado de volta por referido feixe de fibra. A invenção é caracterizada em que ela compreende um tubo retentor de óticos (4) no qual são inseridos em um lado a porção terminal distal (1) do feixe de fibra (2) e no outro lado os outros meios óticos, os últimos compreendendo uma placa (21) colocada em contato com a extremidade (14) do feixe de fibra onde o índice está próximo daquele do núcleo de fibra, e um bloco ótico de focalização (3), uma janela de saída (30) sendo adicionalmente provida adaptada para proporcionar adaptação de indice de modo a eliminar a reflexão parasítica que ocorre na superfície de análise.
