Title (EN) OPTICAL ZOOM DEVICE
(FR) DISPOSITIF DE ZOOM OPTIQUE
Abstract:
(EN) The invention relates to an optical zoom device (1) Optical zoom device (1), comprising a first lens assembly (2), and a second lens assembly (3) following the first lens assembly (2) in the direction of an optical axis (A) of the optical zoom device (1) so that light (L) can pass through the first lens assembly (2) and thereafter through the second lens assembly when travelling along the optical axis (A), wherein said lens assemblies each comprise a focus-adjustable lens (31, 32) as well as an electropermanent magnet (107, 207) or a shape memory alloy (120, 220) for actuating the respective lens (31, 32).
(FR) L'invention concerne un dispositif de zoom optique (1), comprenant un premier ensemble de lentilles (2), et un second ensemble de lentilles (3) suivant le premier ensemble de lentilles (2) dans la direction d'un axe optique (A) du dispositif de zoom optique (1) de sorte que la lumière (L) puisse passer à travers le premier ensemble de lentilles (2) puis à travers le second ensemble de lentilles lorsqu'il se déplace le long de l'axe optique (A), lesdits ensembles de lentilles comprenant chacun une lentille réglable au point focal (31, 32) ainsi qu'un électroaimant permanent (107, 207) ou un alliage à mémoire de forme (120, 220) pour actionner la lentille respective (31, 32).
