Abstract

The invention discloses a mobile phone macro shooting lens which comprises a lens barrel, a lens hole is formed in the front end of the lens barrel, and a diaphragm, a first plastic aspheric lens, a first mylar, a second plastic aspheric lens, a second mylar, a third plastic aspheric lens, a space ring and an optical filter are sequentially fixed in the lens barrel from an object plane to an imageplane along an optical axis. According to the invention, satisfactory optical characteristics and wide total field angle and aperture can be achieved, the diagonal angle is 88.6 degrees, the opticaldistortion is less than 25%, the total optical length is 2.38 mm, the aperture is 1.8, the lens requirement of 2 megapixel level can be realized, and the special application requirement of the lens can be met. The lens is small in size and convenient to use, close-up shooting of the lens does not depend on other close-up shooting accessories, all close-up shooting operations are carried out on thelens, continuous focusing can be carried out between close-up shooting and infinity, and therefore the lens can be rapidly adjusted to a common shooting state from a close-up shooting state, and convenience is provided for a photographer to alternately carry out close-up shooting and common shooting.

Description

technical field [0001] The invention relates to the technical field of optical lenses, in particular to a mobile phone macro shooting lens. Background technique [0002] In order to correctly focus on objects that are extremely close, the macro lens is usually designed to be stretched longer so that the optical center is as far away from the photosensitive element as possible. At the same time, the design of the lens group must also focus on Control of deformation and chromatic aberration at short distances. Most macro lenses have a larger focal length than standard lenses, so they are not entirely suitable for general photography. The miniaturization of the lens is difficult to achieve, the application field is small, and the use is inconvenient. Contents of the invention [0003] The purpose of the present invention is to solve the deficiencies in the prior art, and provide a mobile phone macro camera lens. [0004] To achieve the above object, the present invention i...
