Document Type and Number:
WIPO Patent Application WO/2023/158081
Kind Code:
A1
Abstract:
According to an embodiment of the present disclosure, a lens assembly and/or an electronic device including same comprise at least seven lenses sequentially arranged along an optical axis direction from an object side to an image sensor side. Among the at least seven lenses, a first lens disposed first from the object side is a plastic lens including a convex surface at the object side and having positive refractive power; a second lens disposed second has negative refractive power; a third lens disposed third has a surface at the object side, the surface having a maximum value among the absolute values of the sweep angle, which is 10 degrees or less; a fifth lens disposed fifth has a surface at the object side and a surface at the image sensor side, of which at least one has a maximum value among the absolute values of the sweep angle, which is 45 degrees or greater; a sixth lens disposed sixth includes a concave surface at the image sensor side, wherein a maximum value among the absolute values of the sweep angle of at least one of a surface at the object side and a surface at the image sensor side of the sixth lens is 45 degrees or greater; and a seventh lens disposed seventh is a lens having negative refractive power, and includes a surface at the object side, the surface being aspherical and convex and having at least one inflection point, and a surface at the image sensor side, the surface being aspherical and concave and having at least one inflection point; and one of lens surfaces of the at least seven lenses may have a visible light reflectance of 0.3% or less. Various other embodiments are possible.
