Abstract

La présente invention concerne un système de lentilles à grand angle et une caméra de véhicule le comprenant. Selon l'invention, ce système de lentilles à grand angle comprend des première, deuxième, troisième, quatrième, cinquième et sixième lentilles qui sont disposées dans l'ordre à partir d'un objet. La première lentille est convexe en direction de l'objet et possède donc une réfraction négative. La seconde lentille est concave en direction de l'objet et de la surface de formation d'image et possède donc une réfraction négative. La troisième lentille est convexe en direction de la surface de formation d'image et possède donc une réfraction positive. La quatrième lentille est convexe en direction de l'objet et de la surface de formation d'image et possède donc une réfraction positive. Et la quatrième lentille est formée à partir d'un verre absorbant les rayons infrarouges.
