| Summary: | The invention belongs to the technical field of an optical device and specifically relates to a novel high-definition wide-angle lens. The novel high-definition wide-angle lens comprises a front-end viewing concave lens, a zooming adjusting concave lens, an aperture and an imaging convex lens. The lenses above are arranged in one central axis; and the space between the viewing concave lens and the zooming adjusting concave lens can be adjusted. The high-definition wide-angle lens realizes optical enlargement and reduction of an object by changing the space between the two concave lenses; and the object in the high-definition wide-angle lens is formed into a reduced virtual image through the concave lenses, and the virtual image is projected to the convex lens, is right arranged in the focusing area of the convex lens, and is imaged on a follow-up photosensitive element through focusing of the convex lens. Through the application of the novel high-definition wide-angle lens, full-background wide-angle high-def |
