A kind of lightweight zoom telescopic glasses

Abstract

The invention discloses a lightweight zooming telescope, comprising: a drive control device, a driver, a circular reflective film on the incident surface of an objective lens, a circular reflective film on the exit surface of the objective lens, a circular reflective film on the incident surface of the eyepiece, and a circular reflective film on the exit surface of the eyepiece film, zoom surface Ⅰ, zoom surface Ⅱ, zoom surface Ⅲ, zoom surface Ⅳ, medium Ⅰ and medium Ⅱ; the technical point of this invention is: the curvature of the zoom surface used in the system can be changed when the drive device is working, not only can realize the The high-resolution imaging of long-distance objects can also continuously zoom to quickly identify the tiny details of the object; the present invention adopts a catadioptric hybrid structure, and the zoom surface is coated with a reflective film. When light is incident on the lens, the reflection on the zoom surface of the lens The film makes the light path reflect multiple times in the lens, which reduces the radial size of the telescope. Compared with traditional telescopes, the system is more compact and lightweight, filling the vacancy of zoom glasses in terms of telephoto.

Description

technical field [0001] The present invention relates to a kind of telescopic glasses, more specifically, the present invention relates to a kind of lightweight zooming telescopic glasses. Background technique [0002] Telescope is an indispensable tool for long-distance astronomical or ground observation. After more than 400 years of development, it has been widely used in military operations, astronomical observation, field exploration, security police, and navigation inspection. With the advancement of science and technology, people's demand for telescopes is no longer limited to seeing wider and farther. How to develop a zoom telescope with a larger zoom ratio, a shorter rear working distance, and a lighter weight has become the focus of people's attention. In recent years, with the rise of technologies such as AR, it has become a new demand to make telescopes into lightweight head-mounted products, and the emergence of adaptive lenses with automatic zoom functions provi...

Problems solved by technology

[0003] Traditional zoom telescopes mostly use optical compensation for zoom design. Usually, only one of the objective lens, steering system or eyepiece is continuously zoomed to realize the zoom of the system. The zoom ratio is limited, and the zoom structure is relatively complicated and not light enough. Quantify
