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.
Claims13
An optical imaging system, comprising:
- a first lens having positive refractive power;
- a second lens having refractive power;
- a third lens having refractive power;
- a fourth lens having refractive power;
- a fifth lens having positive refractive power;
- a sixth lens having negative refractive power;
- a seventh lens having positive refractive power;
- and
- an eighth lens having negative refractive power,
- wherein the first to eighth lenses are sequentially disposed on an optical axis from an object side toward an image side,
- wherein TTL/(2*IMG HT)<0.9, where TTL is a distance on the optical axis from an object-side surface of the first lens to an image capturing surface, and IMG HT is half of a diagonal length of the image capturing surface.
