Abstract

"MIRA LUMINOSA DE PROJEçãO PARA MEDIDAS DE PRECISãO DE RAIOS DE CURVATURA DE SUPERFìCIES REFLETORAS ESFéRICAS E NãO ESFéRICAS". Refere-se a presente invenção ao dispositivo (Fig. 1) mira luminosa anelar (1) aplicada para medidas de precisão de raios de curvatura de superfícies refletoras esféricas e não esféricas, com respectivo ponto de fixação para o paciente (2), furos que permitem a observação da Lâmpada de fenda (3), furos a serem iluminados (4), vista lateral (5) e vista anterior (6), utilizando um sistema de iluminação constituído por um cabeçote composto por uma lente de saída do sistema de iluminação, filamento projetado, circulo intermediário, limitador de luz e área útil para a mira, podendo ser projetada ainda de forma alternativa com arcos ou anéis passantes em forma circulinear precisa, podendo ser utilizada para diferentes tipos de iluminação, proporcionando medidas de quaisquer superfícies refletoras, não sendo limitada às medidas oculares.
