Problems solved by technology

[0004] (1) Large size, heavy weight, uncomfortable to wear;
[0005] (2) Poor sealing, easy to enter water, moldy lens;
[0006] (3) Poor sealing, the optical film layer of the lens is easily oxidized, resulting in poor light transmission and reduced optical performance;
[0007] (4) There is no external pressure ring for the front objective lens, and the objective lens is easy to fall off;
[0008] (5) When the user accidentally drops the magnifying glass to the ground, because the front objective lens is heavy, it will fall first, causing the lens to break;
[0009] (6) The optical design is not optimized enough, and there are many peripheral aberrations (distortion) during imaging;
[0010] (7) Once the front objective lens is wet with water, the lens will not be clear;

Embodiment Construction

[0033] The present invention will be further illustrated below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented on the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0034] Such as figure 1 As shown, a novel binocular magnifying glass includes an objective lens 1, an eyepiece 2, an outer lens barrel 3, a sealing ring 4, an inert gas chamber 5, a black inner lens barrel 6, an objective lens pressure ring 7 and an inner pressure ring 8.

[0035] The inner lens barrel 6 is arranged on the inner side of the outer lens barrel 3, and two sealing rings 4 are respectively arranged at the two ends of the outer lens barrel 3 and the inner lens barrel 6, and the objective lens pressure ring 7 directly presses the objective lens 1 onto the sealing ring 4, The i...

Abstract

The invention discloses a novel binocular magnifier. The magnifier comprises an objective lens, an eye lens and an external lens cone for mounting the objective lens and the eye lens. The objective lens and the eye lens both are mounted at the two ends of the external lens cone through sealing rings, and the objective lens, the eye lens and the external lens cone surround a closed inert gas chamber. The novel binocular magnifier provided by the invention is excellent in tightness, firm in installation, excellent in imaging, long in service life and adaptive to an underground environment, and the external surface of the novel binocular magnifier can be processed into various colors for the crowds with different preferences to choose.

Description

technical field [0001] The invention relates to a magnifying glass, in particular to a binocular magnifying glass. Background technique [0002] The binocular magnifying glass lens currently on the market is generally large in size and heavy in weight; the optical glass is glued to the optical lens barrel, and the sealing is poor, and the lens is easy to fall off. [0003] The medical magnifying glass lenses currently on the market mainly have the following disadvantages: [0004] (1) Large size, heavy weight, uncomfortable to wear; [0005] (2) Poor sealing, easy to enter water, moldy lens; [0006] (3) Poor sealing, the optical film layer of the lens is easily oxidized, resulting in poor light transmission and reduced optical performance; [0007] (4) There is no external pressure ring for the front objective lens, and the objective lens is easy to fall off; [0008] (5) When the user accidentally drops the magnifying glass to the ground, because the front objective l...
