Problems solved by technology

However, this kind of lens cover lens usually has few functions and poor transmittance, which reduces the image quality; the structure is simple, the appearance is too single, most of them are black or fully transparent, and it is difficult for the subject to accurately locate the lens position, which affects the shooting effect; This type of lens has poor anti-fouling ability and is easily polluted by fingerprints and other stains

Embodiment 1

[0060] The preparation process of the lens with self-cleaning colorful function is as follows:

[0061] 1. Put the soda-lime glass into detergent, acetone, alcohol, and deionized water in order to ultrasonically clean it for ten minutes, and then dry it with nitrogen after taking it out.

[0062] 2. Transfer the cleaned glass to the evaporation chamber and use electron beams to evaporate Cr to a thickness of 50nm to complete the preparation of the high reflection base film R.

[0063] 3. Pass the glass to the spin coating machine, spin coat UV photoresist, and put it into the drying oven to dry the hard film after spin coating.

[0064] 4. After the film hardening is completed, cover the upper surface with the mask plate Y (the exposure area of ​​the mask plate Y completely coincides with the high transmission area A), expose it under UV light, and use KOH solution to etch the high transmission area A after exposure.

[0065] 5. After the etching is completed, clean with the ...

Embodiment 2

[0077] The preparation process of the lens with self-cleaning colorful function is as follows:

[0078] 1. Put the soda-lime glass into detergent, acetone, alcohol, and deionized water in order to ultrasonically clean it for ten minutes, and then dry it with nitrogen after taking it out.

[0079] 2. Transfer the cleaned glass into the evaporation chamber and use the electron beam to evaporate Cr to a thickness of 40nm to complete the preparation of the high reflection base film R.

[0080] 3. Pass the glass to the spin coating machine, spin coat UV photoresist, and put it into the drying oven to dry the hard film after spin coating.

[0081] 4. After the film hardening is completed, cover the upper surface with the mask plate Y (the exposure area of ​​the mask plate Y completely coincides with the high transmission area A), expose it under UV light, and use KOH solution to etch the high transmission area A after exposure.

Embodiment 3

[0094] The preparation process of the lens with self-cleaning colorful function is as follows:

[0095] 1. Put the soda-lime glass into detergent, acetone, alcohol, and deionized water in order to ultrasonically clean it for ten minutes, and then dry it with nitrogen after taking it out.

[0096] 2. Transfer the cleaned glass to the evaporation chamber and use electron beams to evaporate Cr to a thickness of 60nm to complete the preparation of the high reflection base film R.

[0097] 3. Pass the glass to the spin coating machine, spin coat UV photoresist, and put it into the drying oven to dry the hard film after spin coating.

[0098] 4. After the film hardening is completed, cover the upper surface with the mask plate Y (the exposure area of ​​the mask plate Y completely coincides with the high transmission area A), expose it under UV light, and use KOH solution to etch the high transmission area A after exposure.

Abstract

The invention provides a lens having a self-cleaning colorful function and a preparation method thereof. The lens comprises a lens substrate; a high-transmission lens area and a colorful area, which are disposed on the lens substrate. The high-transmission lens area is disposed on the lens glass central area, and the colorful area is used to cover the area except the high-transmission area. The lens having the self-cleaning colorful function is advantageous in that the transmittance of the light having the required wavelength can reach 99.4%, and the harmful light can be effectively shielded; the light capturing sensitivity of the camera can be improved, and the image quality can be optimized; and at the same time, the preparation of the multi-color lens can be realized, and different colors can be observed from different angles, and then the colorful function can be provided, and the beautiful appearance of the lens can be improved; and the cleaning of the lens is very easy, and the trouble of cleaning the glass surface of the lens can be reduced.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of film applications, in particular to a lens with self-cleaning and colorful functions and a preparation method thereof. [0003] 【Background technique】 [0004] In the cameras of portable devices such as mobile phones and laptops, and professional equipment such as camera telescopes, cover lenses are usually used. Such lenses are generally installed on the outer layer of the lens to protect the inner lens. However, this kind of lens cover lens usually has few functions and poor transmittance, which reduces the image quality; the structure is simple, the appearance is too single, most of them are black or fully transparent, and it is difficult for the subject to accurately locate the lens position, which affects the shooting effect; This type of lens has poor anti-fouling ability and is easily contaminated by fingerprints and other stains. [0005] 【Content of invention】 [0006] In order to solve the probl...
