Abstract
An optical imaging system includes: a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, an eighth lens and a ninth lens, arranged in order from an object side, wherein the first lens and the second lens each have positive refractive power, and 15<v7−v8<25 is satisfied, where v7 indicates an Abbe number of the seventh lens, and v8 indicates an Abbe number of the eighth lens.
Claims20
An optical imaging system comprising:
- a first lens having positive refractive power, a convex object-side surface in a paraxial region thereof and a concave image-side surface in a paraxial region thereof;
- a second lens having refractive power, a convex object-side surface in a paraxial region thereof and a concave image-side surface in a paraxial region thereof;
- a third lens having negative refractive power, a convex object-side surface in a paraxial region thereof and a concave image-side surface in a paraxial region thereof;
- a fourth lens having refractive power;
- a fifth lens having refractive power;
- a sixth lens having refractive power;
- a seventh lens having refractive power;
- an eighth lens having refractive power;
- and
- a ninth lens having negative refractive power and a concave image-side surface in a paraxial region thereof,
- wherein the first to ninth lenses are arranged in order from an object side,
- wherein the optical imaging system has a total of nine lenses,
- wherein 0<f1/f<1.4 is satisfied, where f1 indicates a focal length of the first lens, and f indicates a total focal length of the optical imaging system.
