Present embodiments provide for optical imaging lenses. An optical imaging lens may include five lens elements positioned sequentially from an object side to an image side. By controlling the convex or concave shape of the surfaces of the lens elements and designing parameters satisfying at least one inequality, the optical imaging lens may exhibit better optical characteristics and the total length of the optical imaging lens may be shortened.

Optical imaging lens

Present embodiments provide for mobile devices and optical imaging lenses thereof. An optical imaging lens may include five lens elements positioned sequentially from an object side to an image side. By controlling the convex or concave shape of the surfaces of the lens elements and designing parameters satisfying at least one inequality, the optical imaging lens may exhibit better optical characteristics and the total length of the optical imaging lens may be shortened.

Mobile device and optical imaging lens thereof

Present invention provides an electronic device and an optical imaging lens thereof. The optical imaging lens comprises a first lens element, a second lens element, a third lens element, a fourth lens element and a fifth lens element positioned in an order from an object side to an image side along an optical axis. The first lens element has negative refractive power, the second lens element has a convex portion formed on the object side surface and a concave portion formed on the image side surface, the third lens element has a convex portion formed on the object side surface and the fifth lens element has a convex portion formed on the image side surface. Through controlling the convex or concave shape of the surfaces, designing parameters satisfying an inequality and/or the refracting power of the lens elements, the field of view is broadened, and the better image performance is maintained.

Electronic device and optical imaging lens thereof

The present invention provides a camera device and an optical imaging lens thereof. The optical imaging lens comprises six lens elements positioned in an order from an object side to an image side. Through controlling the convex or concave shape of the surfaces of the lens elements, the view angle of the optical imaging lens is efficiently increased to shows better optical characteristics.

Present embodiments provide for a mobile device and an optical imaging lens thereof. The optical imaging lens comprises five lens elements positioned sequentially from an object side to an image side. Though controlling the convex or concave shape of the surfaces, the refracting power of the lens elements and/or equations between parameters, the optical imaging lens shows better optical characteristics and the total length of the optical imaging lens is shortened.

An imaging optical system includes, in order from the object side to the image side, a first lens element, a second lens element, a third lens element, an aperture stop, a fourth lens element, a fifth lens element, and a sixth lens element arranged along an optical axis. The first lens element has a concave image-side surface in the vicinity of the optical axis. The second lens element has a negative refractive power. The third lens element has a convex object-side surface in a vicinity of an optical axis. The fourth lens element has a convex object-side surface in the vicinity of the optical axis. The fifth lens element has a convex image-side surface in the vicinity of the optical axis. The sixth lens element is made of plastic and has a convex image-side surface in a vicinity of an outer circumference.
