Title (EN) COMPOUND LENS WITH ASPHERIC-DIFFRACTIVE LENS ELEMENTS
(FR) LENTILLE COMPOSITE COMPRENANT DES ÉLÉMENTS DE LENTILLE À DIFFRACTION ASPHÉRIQUE
Abstract:
(EN) An example imaging system includes a compound lens. The compound lens may include a series of lens elements. Each of the lens elements has an aspheric surface on each opposite face. The last lens element of the series has a diffractive optic on a face. The compound lens 5 is to image an object in an object plane onto an image sensor at a resolution of at least 150 line pair/mm at a minimum modulation of 0.39 as applied to the object plane across a visible spectrum comprising red, blue and green wavelengths.
(FR) L'invention concerne un système d'imagerie, donné à titre d'exemple, comprenant une lentille composite. La lentille composite peut comprendre une série d'éléments de lentille. Chacun des éléments de lentille a une surface asphérique sur chaque face opposée. Le dernier élément de lentille de la série comporte une optique diffractive sur une face. La lentille composite (5) est destinée à former une image d'un objet dans un plan d'objet sur un capteur d'image à une résolution d'au moins 150 paires de lignes/mm à une modulation minimale de 0,39 appliquée au plan objet sur un spectre visible comprenant des longueurs d'onde rouge, bleue et verte.
