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, and an eighth lens, sequentially arranged from an object side optical imaging system, and a refractive index of at least one of the lenses is 1.67 or greater.
Claims18
An optical imaging system, comprising:
- a first 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 second 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 third lens having positive refractive power;
- a fourth lens having negative refractive power;
- a fifth lens having refractive power;
- a sixth lens having refractive power and a concave image-side surface;
- a seventh lens having refractive power;
- and
- an eighth lens having refractive power,
- wherein the first to eighth lenses are sequentially disposed on an optical axis from an object side toward an image side,
- wherein the optical imaging system has a total of eight lenses, and
- wherein FOV>70°, where FOV is a field of view of the optical imaging system.
