Abstract

An image capturing apparatus including a cover plate, a first lens element and a second lens element arranged sequentially from an object side to an image side along an optical axis is provided. The number of lens elements in the image capturing apparatus is only two. The image capturing apparatus satisfies: 0.2<f/imgH<0.9, 2.9<N1+N2<3.7, and 2<(OTL−d)/imgH<8, wherein f is an effective focal length of the image capturing apparatus, imgH is a maximum imaging height of the image capturing apparatus, N1 is a refractive index of the first lens element, N2 is a refractive index of the second lens element, OTL is a distance from a tested object to an imaging plane on the optical axis, and d is a thickness of the cover plate.
