Abstract[English]
Miniature optical lenses are disclosed having a ratio of the optical image diameter divided by the total track length that is greater than 0.85. These thin optical lenses are often used in applications requiring large image sensors and small thickness like in consumer electronic applications. The miniature optical lenses presented have fields of view between 130° and 170° or more specifically inside the well-desired 140° to 160° field of view range in order to cover the ultra-wide-angle field of view range. The optical lenses presented also respect some dimensionless ratios in order to maximize the optical performance of the lenses.[French]
Des lentilles optiques miniatures sont divulguées, lesdites lentilles ayant un rapport du diamètre d'image optique divisé par la longueur totale de piste qui est supérieure à 0,85. Ces lentilles optiques minces sont souvent utilisées dans des applications nécessitant des capteurs d'image de grande taille et des petites épaisseurs comme dans des applications électroniques grand public. Les lentilles optiques miniatures présentées ont des champs de vision compris entre 130° et 170° ou plus spécifiquement à l'intérieur du champ de vision de 140° à 160° souhaité afin de couvrir le champ de vision à angle ultra-large. Les lentilles optiques présentées respectent également des rapports sans dimension afin de maximiser les performances optiques des lentilles.
