Abstract

LENTE DE FOCO VARIáVEL E MéTODO DE FABRICAçãO DA MESMA A invenção se relaciona a uma lente de foco variável (60) para a focalização de raios luminosos em trajetos luminosos que passam através da lente ao longo de um eixo óptico <sym>. A lente compreende um arranjo de primeiro e segundo líquidos imiscíveis (67, 68) que possuem índices de refração diferentes e estão em contato ao longo de uma interface óptica refrativa móvel (69) , um volume de gás (72) em contato com um dos líquidos citados e um meio de retenção (70, 74) para o volume de gás afastado dos trajetos luminosos dos raios luminosos que passam através da lente focalização.
