Classification: CPC G | IPC G

Claim 10:
11. An optical imaging system comprising:
a first lens having a negative refractive power;
a second lens having a meniscus shape and a refractive power;
a third lens having a positive refractive power;
a fourth lens having a refractive power;
a fifth lens having a refractive power; and
a sixth lens having a refractive power,
wherein the first to sixth lenses are sequentially arranged in ascending numerical order along an optical axis from an object side of the optical imaging system toward an imaging plane of the optical imaging system,
wherein 0<TTL/FOV<0.1, where TTL is a distance along the optical axis from an object-side surface of the first lens to the imaging plane and FOV is an angle of view of the optical imaging system,
wherein 0.7<(R9−R10)/(R9+R10)<0.9, where R9 is a radius of curvature of an object-side surface of the fifth lens and R10 is a radius of curvature of an image-side surface of the fifth lens,
wherein 3.0<TTL/f<4.0, where f is a total focal length of the optical imaging system, and
0.2<|f1/f2|<0.4, where f1 is a focal length of the first lens and f2 is a focal length of the second lens.
