Abstract

The invention provides a lens group and near-to-eye display equipment, and relates to the technical field of optics; and the lens group comprises a focusing convergent lens assembly, a first optical element and a second optical element which are sequentially arranged in a light outgoing direction. The first optical element is used for enabling an incident light beam to be partially transmitted andpartially reflected, a reflected light beam, reflected by the first optical element, of the convergent light beam emitted from the focus-adjustable convergent lens assembly is emitted towards a second optical element, and after being reflected by the second optical element, the reflected light beam is imaged in a target area through the first optical element. When a myopia or hyperopia user findsthat an image is not clear when watching a picture in a target area through the lens group, the focal length of the whole lens group can be adjusted by adjusting the focal length of the focus-adjustable converging lens assembly, so that the watching requirement of the myopia or hyperopia user when using the lens group is met, and the use experience of the user is improved.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a mirror group and a near-eye display device. Background technique [0002] The near-eye display optical system, also known as the head-mounted display, is a visual display that is used to display augmented reality, virtual reality, mixed reality, etc. on the user's head. It was originally mainly used in military and scientific research fields. With the development, people have more and more understanding and learning about near-eye display technology, and near-eye display technology has gradually entered people's lives. The augmented reality head-mounted display allows people to project virtual images to the human eyes while viewing the surrounding environment. The projected virtual images can be superimposed on the real world perceived by the user. Therefore, the existing combination of virtual display technology and enhanced display technology , to expand the application fie...
