Abstract:
A super wide angle optical system, according to various embodiments of the present invention, comprises: a first lens group including a negative refractive power, and a second lens group including a positive refractive power, in order from an object side; and a device for limiting the size of an aperture or light flux between the first lens group and the second lens group, wherein the first lens group comprises, in order, from the object: a plurality of meniscus lenses which are convex towards the object; a meniscus lens which is concave towards the object next to the meniscus lenses, wherein a lens, which is closest to an image in the first lens group, comprises a positive lens, and wherein the second lens group comprises a cemented lens in which lenses respectively including positive and negative refractive powers are bonded in order from the object side, wherein a lens, which is closest to an image in the second lens group has a positive refractive power. In addition, the super wide-angle optical system may be configured in various manners according to embodiments.

Claim (Index 1):
A super wide-angle optical system comprising:\n a first lens group including a negative refractive power; and a second lens group including a positive refractive power, in order from an object side; and a structure between the first lens group and the second lens group, for restricting a size of one of an aperture and a luminous flux, wherein the first lens group includes a plurality of meniscus lenses convex toward an object, and a meniscus lens concave toward the object side, next to the plurality of meniscus lenses, in order from the object side, and a lens closest to an image in the first lens group is a positive lens, and wherein the second lens group includes a cemented lens of a lens including a positive refractive power and a lens including a negative refractive power bonded to each other, in order from the object side, and a lens closest to the image in the second lens group is a lens including a positive refractive power.
