摘要： A lens assembly includes a first lens, a second lens, a third lens, a fourth lens, and a fifth lens. The first lens is with positive refractive power and includes a convex surface facing an object side and a concave surface facing an image side. The second lens is with positive refractive power. The third lens is with negative refractive power and includes a convex surface facing the object side. The fourth lens is with negative refractive power and includes a concave surface facing the object side. The fifth lens is with positive refractive power and includes a convex surface facing the image side.

摘要： A lens assembly includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a reflective element. The first lens is with refractive power and includes a concave surface facing an object side along an axis. The second lens is with refractive power and includes a convex surface facing the object side along the axis. The third, fourth, and fifth lenses are with refractive power. The reflective element includes a reflective surface. The first, second, third, fourth, and fifth lenses are arranged in order from the object side to an image side along the axis. The reflective element is disposed between the first lens and the fifth lens. The lens assembly satisfies: 2 mm

摘要： A lens assembly is configured to be disposed under a cover glass, in a gap region and outside a display region, including a plurality of lenses, a reflector and an image sensor. The lenses, the reflector and the image sensor are sequentially arranged from an object side to an image side along an optical axis. One of the lenses is adjacent to the object side, has a minimum diameter of clear aperture, and has an outer circumferential portion which is non-circular. The lens assembly satisfies at least one of following conditions: BFL≥VL and BFL≥0.6×DL where BFL is a back focal length of the lens assembly, VL is a minimum side length of the image sensor, and DL is a diagonal length of the image sensor. A lens device includes a cover glass, a case, a display panel and the lens assembly.

摘要： A lens assembly includes a first lens group, a second lens group, a third lens group, a fourth lens group, and a reflective element. The first lens group is with refractive power. The second lens group is with positive refractive power. The third lens group is with positive refractive power. The fourth lens group is with refractive power. The reflective element includes a reflective surface. A light from an object sequentially passes through the first lens group, the second lens group, the third lens group, and the fourth lens group to an image side along an axis. The reflective element is disposed between an object side and the image side along the axis. Intervals of the lens groups are changeable when the lens assembly zooms from a wide-angle end to a telephoto end.
