Abstract

sistema de iluminação para microscópico oftálmico, e seu método de operação a presente invenção revela um sistema de iluminação para microscópio oftálmico e seu método de operação. feixes de luz gerados por led branco (1) passa através do sistema condensador (2) e de relé (4) para produzir iluminação sobre a retino do olho (11), o limite da iluminação sendo determinado pelo limitador de obturador (3). para realçara visualização do brilho vermelho, um único feixe de fonte é, então, dividido em dois feixes com uso de sistema divisor (5) que contém divisor de feixe (5a) e espelho (5b). feixes transmitidos (8a) e feixes refletidos (8b) são feitos para focalizar sobre áreas circulares revestidas com material refletivo (6a, 6b) de divisor de feixe virtual (6) que é posicionado coaxialmente com o sistema de observação (9) do microscópio. feixe focalizado passa, então, através da lente objetiva (7) do sistema de microscópio. feixes refletidos pela retina (11) passam, então, através da lente objetiva (70 e alcançam o sistema de observação (9) via divisor de feixe virtual.
