Optical image capturing system

An optical image capturing system includes, along the optical axis in order from an object side to an image side, a first lens, a second lens, a third lens, a fourth lens, and a fifth lens. At least one lens among the first to the fifth lenses has positive refractive force, wherein the fifth lens can have negative refractive force, wherein both surfaces thereof are aspheric, and at least one surface thereof has an inflection point and wherein the first to the fifth lenses in the optical image capturing system have refractive power whereby the optical image capturing system can increase aperture value and improve the imaging quality for use in compact cameras.

Lens driving device, camera module, and portable device

The present embodiment of the present invention relates to a lens driving device, comprising: a housing; a bobbin disposed in the housing; a first coil disposed on the bobbin; a magnet which is disposed on the housing and faces the first coil; a base disposed under the housing; a substrate which is disposed on an upper surface of the base and comprises a circuit member including a second coil facing the magnet; an upper elastic member disposed on an upper portion of the bobbin and coupled to the bobbin and the housing; a support member coupled to the upper elastic member; and a terminal member elastically connecting the support member with the substrate, wherein the terminal member comprises; a first connector coupled to the substrate; and a second connector coupled to the support member; and wherein the second connector is disposed at a position lower than the first connector.

Optical imaging lens and electronic device comprising the same

An optical imaging lens set includes a first lens element with an object-side surface of a convex part in a vicinity of the optical axis, a second lens element with an image-side surface of a concave part in a vicinity of its periphery, the first lens element being glued to the second lens element to eliminate an air gap, a third lens element with an object-side surface of a concave part in a vicinity of its periphery, a fourth lens element and a fifth lens element of plastic material, ALT being the total thickness of the five lens elements and G.sub.max being the max value of the air gap from the first lens element to the fifth lens element so that ALT/G.sub.max2.2.
