Mobile phone wide-angle zoom lens

Abstract

The invention relates to a mobile phone wide-angle zoom lens, which comprises a first lens, a second lens, a third lens, a fourth lens, a diaphragm, a fifth lens and a sixth lens sequentially from anobject space to an image space. The first lens, the second lens and the third lens are all negative meniscus spherical lenses; both sides of the fourth lens are even aspheric negative meniscus lenses;both sides of the fifth lens are even aspheric positive meniscus lenses; both sides of the sixth lens are even aspheric biconcave lenses. The whole zoom lens is low in lens quantity, small in size, smaller than 12mm in optical total length and approximate to two times in optical zoom ratio. An expected zoom ratio can be achieved by changing of air spaces among the lenses, and high imaging qualitycan be realized in a whole zoom range.

Description

technical field [0001] The invention relates to an optical lens, in particular to a mobile phone wide-angle zoom lens. Background technique [0002] In recent years, the rapid development of smart phones has made people have higher and higher requirements for the functions of mobile phones. The camera level of mobile phones has become an important indicator for consumers to measure the performance of mobile phones. [0003] The existing mobile phone lenses are limited by the narrow space of the mobile phone. Most of them use fixed-focus lenses with fixed focal length and fixed lens angle of view. They cannot obtain the best shooting effect through optical zoom like traditional cameras. The means of digital zoom will still reduce the imaging quality, and the imaging effect of optical zoom will not be achieved. Contents of the invention [0004] The purpose of the present invention is to provide a mobile phone wide-angle zoom lens with small size, few lenses and high imagin...
