Abstract
An optical imaging system includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens, sequentially disposed from an object side. The first lens has negative refractive power, an image side surface thereof is concave, and an angle of view of the optical system including the first lens to the sixth lens is 100° or more. When a focal length of the first lens is f1_1, and a total focal length of the optical system including the first lens to the sixth lens is F1, 1.0<|f1_1/F1|<2.0 is satisfied.

An optical imaging system comprising:
- a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens, sequentially disposed from an object side,
- wherein the first lens has negative refractive power, an image side surface thereof is concave, and an angle of view of the optical imaging system comprising the first lens to the sixth lens is 100° or more, and
- wherein when a focal length of the first lens is f1_1, and a total focal length of the optical imaging system comprising the first lens to the sixth lens is F1, 1.0<|f1_1/F1|<2.0 is satisfied.
An optical imaging system comprising:
- a first optical imaging system, a second optical imaging system, and a third optical imaging system having different angles of view from each other,
- wherein among the first optical imaging system to the third optical imaging system, when an angle of view of an optical imaging system having the widest angle of view is FOV1, and an angle of view of an optical system having the narrowest angle of view is FOV3, 1.5<FOV1/FOV3<4.0 is satisfied, and
- wherein the optical imaging system having the widest angle of view among the first optical imaging system to the third optical imaging system comprises:
- a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens, sequentially disposed from an object side,
- wherein the first lens has negative refractive power, an image side surface thereof is concave, and an angle of view of an optical system comprising the first lens to the sixth lens is 100° or more, and
- wherein when a focal length of the first lens is f1_1, and a total focal length of the optical system comprising the first lens to the sixth lens is F1, 1.0<|f1_1/F1|<2.0 is satisfied.
