High-definition 4K optical imaging system and method

Abstract

The invention relates to a high-definition 4K optical imaging system. A lens I is a convex-concave negative-focus spherical glass lens. A lens II is a biconcave negative-focus spherical glass lens. Alens III is a biconvex positive-focus spherical glass lens. A lens IV is a biconvex positive-focus spherical glass lens. A lens V is a biconvex positive-focus spherical glass lens. A lens VI is a biconcave negative-focus spherical glass lens. A lens VII is a biconvex positive-focus spherical glass lens. A lens VIII is a concave-convex negative-focus spherical glass lens. A lens IX is a biconvex positive-focus spherical glass lens. A lens X is a concave-convex negative-focus spherical glass lens. The lens II and the lens III are combined to form a first cemented lens. The lens V and the lens VIare combined to form a second cemented lens. The lens VII and the lens VIII are combined to form a third cemented lens, and the lens IX and the lens X are combined to form a fourth cemented lens. According to the invention, the problem of chromatic aberration of the system is effectively solved, the tolerance sensitivity of the optical system can be reduced, the process conditions are improved, and the imaging quality of the lens is improved.

Description

technical field [0001] The invention relates to the field of optical imaging, in particular to a high-definition 4K optical imaging system and method. Background technique [0002] Light is everywhere around us, and optical imaging technology is inseparable from our lives, such as various cameras, video cameras, telescopes, projectors, etc. Optical systems refer to various optical components such as lenses, mirrors, prisms, and diaphragms A system assembled in a certain order. Usually used for imaging or optical information processing. The optical system composed of two or more refracting spheres with the center of curvature on the same straight line is called a coaxial spherical system, and the straight line where the center of curvature is called the optical axis. In addition to the related issues of Gaussian optics, an optical system also needs to consider a series of issues such as the size of the imaging range, the size of the imaging beam aperture angle, the width of...
