Abstract

The invention relates to a processing technology of a small-size camera ultrathin glass lens. The technology comprises the steps that firstly glass raw material is cut by a glass cutting machine according to 15-20 times of the external contour size of the camera ultrathin glass lens and then chemical thinning and CNC formation are performed; and then cleaning and chemical toughened polishing are performed, and finally screen printing of the frame, laser cutting and FGAR film coating are performed. The beneficial effects are that application of the small-size ultrathin camera lens on the mobile phone, the tablet and the computer can be realized through the technology so that the product is enabled to be more exquisite and beautiful.

Description

[0001] Technical field: [0002] The invention relates to the field of glass processing, in particular to a processing technology for an ultra-thin glass lens of a small-sized camera. [0003] Background technique: [0004] Glass lens: a lens made of optical glass, which is more scratch-resistant and high-temperature-resistant than lenses made of other materials. The lens is thinner and not easy to scratch. Above 1.72, up to 2.0), etc., but the glass is fragile and the material is heavy. The glass lens without color is called optical white support (white sheet), and the pink sheet in the colored glass lens is called Croxel lens (red sheet), which can absorb ultraviolet rays and have a slight absorption effect on strong light. The nouns associated with glass lenses include: refractive index, Albert number, lens center optics, light transmittance, polarized glass lenses, etc. [0005] Invention content: [0006] The technical problem to be solved by the present invention is to...
