The present disclosure provides a camera module and an optical lens thereof, an optical lens element and a manufacturing method therefor, and a method for assembling a large wide-angle camera module, wherein the camera module comprises a lens and a photosensitive assembly. The lens comprises a lens barrel, at least one first lens element unit and at least one second lens element unit, and is further provided with at least one notch, wherein the first lens element unit and the second lens element unit are disposed in the lens barrel, and the first lens element unit is configured as a non-rotating body, and wherein the notch is provided in the lens barrel, or the notch is formed in the first lens element unit, or the notch is formed in the second lens element unit, and the first lens element unit is marked by means of the notch.

Camera module and optical lens thereof, optical lens sheet and fabrication method therefor, and method for assembling large wide-angle camera module

Disclosed are an optical system and a camera module. The optical system sequentially includes, from an object side to an image side, a first lens, a reflective element and a second element group. The first lens has a positive refractive power, and allows propagation of light rays along a first optical axis. The reflective element changes light rays emitted from the first lens from propagating along the first optical axis to propagating along a second optical axis. The first lens and the reflective element constitute a first element group. The second element group has a positive refractive power. During an anti-shaking process, the position of an image plane of the optical system remains fixed, and the first element group rotates around a direction parallel to the second optical axis, an effective focal length f1 of the first lens and an effective focal length EFL of the optical system satisfy: 1.9<|f1/EFL|<3.0.

Optical system and camera module

A head-mounted viewable device which includes a display configured to display and project a virtual scene image to a user's eye, a VR optical lens configured to construct an optical path between the display and the user's eye for allowing a virtual scene image being observed by the user's eye, and, an eye-tracking system configured to detect a sight direction of the user's eye and adjust a display position of the virtual scene image based on the detected sight direction. The eye-tracking system includes at least one light source configured to project the detection light and a receiving module configured to receive the reflected detection light reflected to determine the sight direction of the user's eye. The receiving module is positioned at a side of the VR optical lens and arranged to face towards the user's eye such that the detection light reflected by the user's eye is directly received by the receiving module.
