Title (EN) LENS ARRANGEMENT FOR A VARIABLE FOCUS OPTICAL DEVICE
(FR) ENSEMBLE LENTILLES POUR DISPOSITIF OPTIQUE À FOCALE VARIABLE
Abstract: front page image
(EN)A lens arrangement for a variable focus optical device comprising: a first lens group of positive optical power; a second lens group of a negative optical power; said first lens group or second lens group including at least two immiscible liquids whose interface can change shape in response to changes in an applied voltage; and a third lens group of a positive optical power.
(FR)L'invention concerne un ensemble lentilles pour un dispositif optique à focale variable, cet ensemble lentilles comprenant un premier groupe de lentilles de puissance positive, un deuxième groupe de lentilles de puissance négative, le premier et le deuxième groupe de lentilles comportant au moins deux liquides non miscibles dont l'interface peut changer de forme en réponse aux variations de tension appliquée, ainsi qu'un troisième groupe de lentilles de puissance positive.
