Optical shot for image capture

Abstract

The invention discloses an optical shot for image capture. The optical shot comprises five lenses with refractive power, which, from an object side to an image side, are sequentially a first lens with positive refractive power, a second lens with negative refractive power, a third lens, a fourth lens with positive refractive power and a fifth lens with negative refractive power, wherein the object side surface of the first lens is a convex surface; the object side surface of the second lens is a concave surface; the object side surface of the fourth lens is a convex surface, and at least one surface of the object side surface and the image side surface of the fourth lens is an aspheric surface; and the object side surface of the fifth lens is a concave surface, and at least one inflectionpoint is formed on the image side surface of the fifth lens. The optical shot for image capture is also provided with an aperture and an electric photosensitive element for imaging a photographed object; and the aperture is arranged between the photographed object and the second lens. Through the mode of configuring the lens group, the shot volume can be effectively reduced, the sensitivity of anoptical system can be reduced, and higher resolution power can be acquired.

Description

technical field [0001] The invention relates to an optical lens for taking images, in particular to a miniaturized optical lens for taking images applied to portable electronic products. Background technique [0002] In recent years, with the rise of portable electronic products with imaging functions, the demand for miniaturized photographic lenses has increased day by day, and the photosensitive element of general photographic lenses is nothing more than a charge coupled device (CCD) or There are two types of Complementary Metal-Oxide Semiconductor Sensor (CMOS Sensor), and with the improvement of semiconductor process technology, the pixel size of the photosensitive element is reduced, and the miniaturized photographic lens is gradually developing towards the high-pixel field. Therefore, , the requirements for image quality are also increasing. [0003] Traditional miniaturized photographic lenses mounted on portable electronic products mostly adopt a four-piece lens str...

Problems solved by technology

[0004] However, due to the prevalence of high-standard mobile devices such as smart phones (Smart Phone) and PDA (Personal Digital Assistant), the miniaturized photographic lens has rapidly increased in terms of pixels and image quality, and the existing four-element lens group will not be able to meet the requirements. Higher-end photographic lens modules, coupled with the continuous development of high-performance and thinner electronic products, miniaturized photographic lenses with high pixels and high performance have become an important goal for the development of high-end electronic products.
