Abstract

Abstract Translated from German Einfach handhabbare Mikrolinsen werden hergestellt, indem in einer Glasplatte rotationssymmetrische Vertiefungen angebracht werden, dann mit einem Abscheidungsprozeß aus der Dampfphase glasartige Schichten auf der Platte abgeschieden werden, bis die Vertiefungen völlig ausgefüllt sind, wonach die Dicke der beschichteten Glasplatte auf den ursprünglichen oder einen kleineren Wert reduziert wird. Zwei auf diese Weise hergestellte Linsen werden dann zu einer Linse vereinigt, indem die eingebetteten Linsen mit ihren flachen Seiten aneinandergelegt werden. Easy-to-use microlenses are made by making rotationally symmetrical depressions in a glass plate, then using a vapor deposition process to deposit glass-like layers on the plate until the depressions are completely filled, after which the thickness of the coated glass plate is restored to the original value or a smaller value is reduced. Two lenses produced in this way are then combined to form one lens by placing the embedded lenses with their flat sides together.
