Embodiment 1

[0013] An absorbing filter protective glass, which uses quartz glass or sapphire glass 1 as the material, with a mass percentage of 90%. The surface of the absorbing filter protective glass is coated with an infrared cut-off film 2 and an anti-reflection film 3. In the smelting process, 10% by mass of phosphorus pentoxide and other light-absorbing substances are added.

Embodiment 2

[0015] An absorbing filter protection glass, which uses quartz glass or sapphire glass 1 as the material, with a mass percentage of 99.5%. In the smelting process, 0.5% by mass of phosphorus pentoxide and other light-absorbing substances are added.

Embodiment 3

[0017] An absorbing filter protective glass, which uses quartz glass or sapphire glass 1 as the material, with a mass percentage of 95%. The surface of the absorbing filter protective glass is coated with an infrared cut-off film 2 and an anti-reflection film 3. In the smelting process, 5% by mass of phosphorus pentoxide and other light-absorbing substances are added.

Abstract

The invention discloses absorption type filtering protection glass. The absorption type filtering protection glass adopts quartz glass or sapphire glass as a material, the surface of the absorption type filtering protection glass is plated with an infrared cut-off film and an antireflection film, and light-absorbing substances such as phosphorus pentoxide is added into an absorption type filtering protection glass smelting process. According to the absorption type filtering protection glass disclosed by the invention, phenomena of halo, ghosting and darkened picture caused by light reflection and absorption can be effectively reduced in an image module optical system, and a phenomenon of chromatic aberration of incident light due to angle changes can be improved.

Description

technical field [0001] The invention relates to the field of image modules, in particular to an absorbing filter protection glass. Background technique [0002] The image module device is an optical component used to generate images. It is composed of protective glass, optical lens, filter, lens holder, Sensor, PCB, connectors, and peripheral electronic devices. It is widely used in video recording and photography of mobile electronic equipment. [0003] The protective glass, optical lens, and optical filter in the existing image module form an optical system. After the light is reflected and absorbed by the multi-layer optical glass, the image quality of the module is affected. Contents of the invention [0004] The technical solution of the present invention is realized in the following way: aiming at the defect of the imaging quality of the existing image module, the patent of the present invention discloses an absorbing filter protective glass, which can improve the im...
