Abstract

lentes refrativas - difrativas, prevê um aparelho de lente multifocal; o aparelho compreende um corpo de lente sendo formado com uma pluralidade de regiões anulares concêntricas separadas por degraus inclinados; as regiões concêntricas afetam a difração e a refração da luz incidente, ao passo que os degraus são substancialmente desprovidos de qualquer força difrativa ou refrativa.lerefractive lenses - diffractive, provides for a multifocal lens apparatus; the apparatus comprises a lens body being formed with a plurality of concentric annular regions separated by inclined steps; the concentric regions affect the diffraction and refraction of incident light, while the steps are substantially devoid of any diffractive or refractive forces.le
