Abstract

Patente de Invenção: "MEDIçãO DE RAIO POSTERIOR DECURVATURA E ESPESSURA DE MATERIAL CENTRAL DEUMA LENTE DE CONTATO EM SOLUçãO". O pedido se refere aum método e a um dispositivo para, simultaneamente, medir aespessura do material central e o raio posterior de curvatura deuma lente e em particular de um lente oftálmica tórica descartável.Uma onda ultra-sónica é irradiada por um transdutor em direção auma lente e refletida fora das superfícies frontal e traseira da lente.Com base no lapso de tempo entre os respectivos ecos, aespessura do material central e a altura sagital da lente sãodeterminadas. O raio posterior de curvatura é calculado a partir derelações conhecidas entre a corda de um círculo e a altura sagital.
