Abstract

The embodiment of the invention discloses an ultra-wide angle high-pixel fisheye optical system. As shown in the graph 1, the system comprises from an object surface to an image surface along an optical axis in order: a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens and an eighth lens. Besides, the embodiment of the invention further provides a camera module. The camera module is mainly formed by 8 lenses, and is few in the number of the lenses and simple in structure; and moreover, mutual combination of different lenses and reasonable distribution of focal power are performed to allow the ultra-wide angle high-pixel fisheye optical system and the camera module to have good optical performances such as a 200-degree ultra-wide angle and more than 20 million high pixels, and are suitable for a professional panorama VR camera and a mirrorless camera.

Description

Technical field: [0001] The invention relates to an optical system and a camera module for its application, in particular to an ultra-wide-angle high-pixel fisheye optical system and a camera module for its application. Background technique: [0002] The existing optical systems or camera modules used in professional-grade panoramic VR cameras and mirrorless cameras generally have the problems of large number of lenses and complex structures. Invention content: [0003] In order to overcome the problems of large number of lenses and complex structures in the existing optical systems or camera modules used in professional-grade panoramic VR cameras and mirrorless cameras, an embodiment of the present invention provides an ultra-wide-angle high-pixel fisheye optical system. [0004] An ultra-wide-angle high-pixel fisheye optical system, which sequentially includes: a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens along ...
