Abstract
(DE) Beschrieben wird eine Vorrichtung zur Bestimmung des Abstandes zwischen der Pupillenebene eines Auges und der Fassungsebene einer vor dem Auge befindlichen Brillenfassung, mit einem optischen Element, das längs einer Trennlinie zweigeteilt ist, und dessen beide Teile unterschiedliche prismatische Wirkungen aufweisen, und einer Einrichtung, die die Verschiebund der beiden Teilbilder erfaßt.
(EN) Disclosed is a device for detecting the distance between the pupil plane of an eye and the frame plane pertaining to a spectacle frame that is situated in front of the eye. The inventive device comprises an optical element which is separated into two components along a separating line. Said two components are provided with different prismatic effects. The inventive device also comprises a device which detects the displacement of the two partial images.
