摘要： The present invention provides a high-performance, thin wide-angle lens suitable for imaging elements with high pixel counts. The wide-angle lens includes, from an object side to an image plane side: a first lens group including a first lens having a negative refractive power and a second lens having a positive refractive power; and a second lens group including a third lens having a negative refractive power, a fourth lens having a positive refractive power, and a fifth lens having a positive refractive power. The fourth lens is bonded to the third lens. The fifth lens is formed with at least one of its convex surfaces being an aspherical surface.

摘要： A photographing lens includes an aperture stop having a predetermined aperture, a first lens having a positive refractive power and a convex surface facing the object side, a second lens having a positive refractive power and aspherical surfaces on both sides, the object-side aspherical surface being concave, and a third lens having a negative refractive power and aspherical surfaces on both sides, the object side surface being convex. The aperture stop and the first, second, and third lenses are arranged in order from the object side toward the image-plane side. With such a three-unit, three element lens configuration, a proper back focus is ensured, aberrations are properly corrected, and the total lens length and thickness of the photographing lens are reduced. The photographing lens can be suitably applied to high-resolution image pickup devices with a million pixels or more.

摘要： The photographing lens of the present invention includes, starting from the object side: an aperture stop having a predetermined aperture; a first lens group having a positive overall refractive power; a second lens group having a positive overall refractive power; and a third lens group having a positive overall refractive power. The first lens group is a cemented lens with, from the object side, a first lens with a positive refractive power and a second lens with a negative refractive power. The second lens group includes a third lens with a positive refractive power and at least one aspherical surface. The third lens group includes a fourth lens with a positive refractive power and at least one aspherical surface. The present invention provides a thin photographing lens for mobile devices with cameras, which has a short total length and an exit angle up to around 20null and corrects various aberrations.

摘要： A zoom lens with a slim and compact design has arranged in sequence from the object side to the image plane side a first lens group having a negative refractivity, a second lens group having a positive refractivity, and a third lens group having a positive refractivity. The first lens group is formed from a first lens having a negative refractivity and a second lens having a positive refractivity. The second lens group is formed from a third lens having a positive refractivity and a fourth lens and a fifth lens. The fourth and fifth lens are joined together and have a negative refractivity. The third lens group is formed from a sixth lens having a positive refractivity. The zoom lens has a short length when retracted and extended, and a design that is compact and thin.
