Abstract

The invention discloses a long-focus module, which comprises a first prism, a first lens unit, a second prism, a second lens unit and a sensing element, wherein the incident parts of the first prism,the first lens unit and the second prism form a first light incident path, the exit part of the second prism, the second lens unit and the sensing element form a second light incident path, and the second prism inverts a propagation path of light, so that the first light incident path and the second light incident path are positioned on the same side of the second prism. According to the invention, through the reverse design of the second prism, the light propagation path is divided into the first light incident path and the second light incident path, and the zoom lenses are respectively arranged on the first light incident path and the second light incident path, so that the problem that the size of the long-focus module is too large due to the zoom requirement is solved. The invention further provides a double-camera module and electronic equipment.

Description

technical field [0001] The invention relates to the field of optics, in particular to a telephoto module, a dual-camera module and electronic equipment. Background technique [0002] With the rise of live broadcast and short video software in the Internet era, electronic devices have put forward higher requirements for their own camera modules, but limited by the space provided by electronic devices, camera modules need to be installed in the same size. To obtain a higher zoom ratio, however, for a general camera module, a higher zoom ratio means a longer focal length, and a larger size of the camera module is required. Contents of the invention [0003] This application provides a telephoto module, through the 180° inversion of the second prism, the light propagation path is divided into the first incident light path and the second incident light path, on the first incident light path and the second incident light path Set the lens separately to overcome the problem of t...
