Glass and plastic mixed front mobile phone lens structure

Abstract

The invention discloses a glass and plastic mixed front mobile phone lens which is composed of a glass spherical mirror (1), a first plastic aspherical mirror (2), a diaphragm (3), a second plastic aspherical mirror (4), a third plastic aspherical mirror (5), a fourth plastic aspherical mirror (6) and a light filter (7) which are coaxially arranged in turn from the object side to the image side. The glass spherical mirror (1) and the fourth plastic aspherical mirror (6) are negative lenses. The first plastic aspherical mirror (2), the second plastic aspherical mirror (4) and the third plasticaspherical mirror (5) are positive lenses. The implemented F number is 1.6 and the full viewing angle is 96 degrees. The camera lens is composed of one spherical glass lens and four plastic asphericallenses through appropriate optimization and material combination so that the imaging quality can be effectively enhanced and the lens size can be reduced.

Description

technical field [0001] The invention relates to the field of mobile phone front cameras, in particular to a glass-plastic hybrid front mobile phone lens structure. Background technique [0002] With the gradual promotion of applications such as self-portrait and mobile phone video in daily life, people have higher and higher requirements for the camera effect of the front camera of the mobile phone, and the front camera is also developing to a high point of 10 million pixels. [0003] For the camera, the F number determines the brightness of the camera's perception of the picture, and the FOV determines the size of the camera's shooting range. Because with the increase of the field of view of the wide-angle lens, the distortion of the captured image is also greater, so the current mobile phone front camera The F-number of the camera is above 2, and the angle of view is mostly within 60 degrees, resulting in a smaller camera brightness and shooting range. Therefore, it is of ...
