Description

Technical Field

[0001] The utility model relates to the technical field of quartz glass, in particular to an ultra-thin far-ultraviolet optical quartz glass lens. Background Art

[0002] In the field of optical lenses, far-ultraviolet quartz glass is used to make various optical lenses, including but not limited to digital camera lenses, computer display screens, CCD camera lenses, etc. These lenses exhibit excellent light transmission performance in the ultraviolet to infrared wavelength range, making them widely used in optical instruments.

[0003] The existing quartz glass lenses on the market do not have effective protection capabilities. Since they are composed of single lenses, the lenses are very fragile. When scratches or collisions occur on the quartz glass lenses, they are easily damaged, which causes inconvenience during use. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to propose an ultra-thin far-ultraviolet optical quartz glass lens.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An ultra-thin far-ultraviolet optical quartz glass lens, comprising a protective glass and a far-ultraviolet quartz glass. One side of the protective glass is fixedly connected with an anti-glare film, one side of the anti-glare film is fixedly connected with a high-temperature resistant film, and one side of the high-temperature resistant film is fixedly connected with a transparent scratch-resistant film.

[0007] As a further scheme of the utility model, a sealant is provided on the outer sides of the protective glass, the far-ultraviolet quartz glass, the anti-glare film, the high-temperature resistant film and the transparent scratch-resistant film.

[0008] As a further scheme of the utility model, the high-temperature resistant film is a PET flame retardant film.

[0009] As a further scheme of the utility model, the transparent scratch-resistant film is a TPU film.

[0010] As a further scheme of the utility model, the anti-glare film is a nano-silica film.

[0011] The beneficial effects of the utility model are as follows:

[0012] 1. The far-ultraviolet optical glass is protected by the protective glass, thereby increasing the strength of the lens, avoiding the easy breakage of the far-ultraviolet optical glass. At the same time, the transparent scratch-resistant film makes the anti-abrasion performance of the lens more excellent, and can resist the wear and scratches brought by the daily use of the lens, improving the protection effect of the lens.

[0013] 2. In the present utility model, the high-temperature resistant film endows the lens with the characteristics of high flame retardancy and high temperature resistance. It is colorless and transparent in appearance, ensuring high clarity of the lens. At the same time, the anti-glare film makes the lens have excellent anti-glare effect.

[0014] 3. In the present utility model, a sealant is provided to seal the joints between the protective glass, far ultraviolet quartz glass, anti-glare film, high-temperature resistant film and transparent scratch-resistant film, avoiding the phenomenon of easy cracking at the joints.
