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.
Claims27
An optical imaging system comprising:
- 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,
- wherein 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, and
- wherein 0.5<L7S2/L8S1<1.2 is satisfied, where L7S2 indicates a radius of curvature of an image-side surface of the seventh lens, and L8S1 indicates a radius of curvature of an object-side surface of the eighth lens.
