A lens assembly according to the present disclosure includes at least one lens, a spacer, and a barrel. The at least one lens having an effective region configured to refract light, a flange region formed on at least a part surrounding the effective region, and a first cut formed on a sub region of the flange region. The spacer includes a second cut formed to correspond to the first cut and is configured to maintain a distance between multiple lenses mounted in the barrel. Moreover, the barrel is configured to receive the at least one lens and the spacer, in which the lens and the spacer are disposed inside the barrel such that the first cut and the second cut correspond to a third cut formed on an outer circumferential surface of the barrel. Various embodiments of the lens assembly and an electronic device including the same are described herein.

Lens assembly and electronic device including the same

An optical lens assembly utilized as part of an electronic device may be configured to provide a compact structure and/or a thin profile for the electronic device while maintaining high resolution, via the use of at least one lens having planar surfaces in partial portions thereof. An optical lens assembly may include at least two lenses arranged from an object side to an image side, where at least one of the at least two lenses includes an object side surface with a planar central region, an image side surface that also has a planar central region and a peripheral region having an aspherical surface. Various embodiments with differing lens arrangements are disclosed.

Optical lens assembly and apparatus having the same

Disclosed is an image capturing optical system including, in order from an object side, a first lens having positive refractive power and concave upwards, a second lens having positive refractive power, a third lens having negative refractive power, a fourth lens having positive refractive power, a fifth lens having positive refractive power and including at least one inflection points on the object side or an upper surface, and a sixth lens having negative refractive power and being convex upwards.

Image capturing optical system

A photographing lens system and a photographing apparatus including the photographing lens system are provided. The photographing lens system may include a first lens having a negative refractive power, a second lens having a positive refractive power, a third lens having a negative refractive power, a fourth lens having a negative or positive refractive power, a fifth lens having a negative refractive power, and a sixth lens having a negative or positive refractive power. The first to sixth lenses may be sequentially arranged in a direction from an object side to an image side.

Photographing lens system and photographing apparatus having the same

Photographing lenses and a photographing apparatus including the photographing lenses using several lenses and to incorporate high-performance photographing apparatuses in slim portable terminals while maintaining optical characteristics and aberration characteristics of the high-performance photographing apparatuses. The photographing lenses include: a first lens having a positive refractive power and a convex object-side surface; a second lens having a positive refractive power; a third lens having a negative refractive power; a fourth lens having a convex image-side surface; a fifth lens having an object-side surface and an image-side surface that are concave in a region around an optical axis of the photographing lenses; and a sixth lens having an image-side surface that is concave in a region around the optical axis of the photographing lenses. The first lens to sixth lens are sequentially arranged in a direction from an object side to an image side.

Photographing lenses and photographing apparatus

A circuit for controlling a liquid crystal rear-vision mirror is disclosed. The liquid crystal rear-vision mirror is equipped in an automobile to sense the amount of lights incident upon the mirror itself from a headlight of another automobile following behind. When the level of incident lights goes higher than a pre-determined level, the circuit generates a pulse signal of a fixed period to make the liquid crystal shutter properly function so that the amount of said incident light reflecting from the mirror to the driver will be decreased to a level adequate to secure driving safety.
