Abstract:
(EN) An optical lens system is disclosed. An optical lens system according to the present invention can be installed in a camera module and be used for capturing an image. An optical lens system according to the present invention comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens arrayed between an object and a sensor, on which an image of the object forms, sequentially from the object side to the sensor side. The first lens has a negative refractive power. The second lens has a positive refractive power. The third lens has a positive refractive power, and the object-side surface of the third lens is convex at a radical axis. The fourth lens has a refractive power. The object-side surface of the fourth lens is convex at a radical axis and is concave in the periphery within an effective diameter of the radical axis. The sensor-side surface of the fourth lens is concave at the radical axis. The object-side surface and sensor-side surface of the fourth lens are both aspheric surfaces. The fifth lens has a positive refractive power, and the object-side surface of the fifth lens is concave at a radical axis and is an aspheric surface. The sixth lens has a refractive power. The sensor-side surface of the sixth lens is concave and has at least one inflection point within an effective diameter. The object-side surface and sensor-side surface of the sixth lens are both aspheric surfaces. A diaphragm is positioned between the second lens and third lens. Θ is a viewing angle in a diagonal direction of the optical lens system. F is a focal length of the optical lens system. TTL is a length along an optical axis from the object-side surface of the first lens to the sensor. BFL is a length along an optical axis from the sensor-side surface of the sixth lens to the sensor. And the following conditional expressions are satisfied. Conditional expressions: -1.00

Un système de lentilles optiques selon l'invention comprend une première lentille, une deuxième lentille, une troisième lentille, une quatrième lentille, une cinquième lentille et une sixième lentille déployées entre un objet et un capteur, sur lequel une image de l'objet est formées forme, de manière séquentielle du côté objet au côté capteur. La première lentille présente une vergence négative. La deuxième lentille présente une vergence positive. La troisième lentille présente une vergence positive, et la surface côté objet de la troisième lentille est convexe au niveau d'un axe radical. La quatrième lentille présente une vergence. La surface côté objet de la quatrième lentille est convexe au niveau d'un axe radical et elle est concave à la périphérie à l'intérieur d'un diamètre effectif de l'axe radical. La surface côté capteur de la quatrième lentille est concave au niveau de l'axe radical. La surface côté objet et la surface côté capteur de la quatrième lentille sont toutes deux des surfaces asphériques. La cinquième lentille présente une vergence positive, et la surface côté objet de la cinquième lentille est concave au niveau d'un axe radical et elle est une surface asphérique.
