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
The present invention relates to image module field, particularly the absorption optical filtering cover glass of one.
Background technology
Image die set is the optical module generating image, is made up of, is widely used in the shooting of mobile electronic device, takes pictures cover glass, optical lens, optical filter, microscope base, Sensor, PCB, connector, periphery electron device.
Cover glass, optical lens, optical filter composition optical system in existing image module, light is through multilayer optical glass-reflected with after absorbing, and module image quality is affected.
Summary of the invention
Technical scheme of the present invention is achieved in that the present invention patent discloses a kind of absorption optical filtering cover glass, can improve image quality in the optical system of image module for existing image module image quality defect.
For achieving the above object, the present invention patent discloses a kind of absorption optical filtering cover glass, adopt quartz glass or sapphire glass as material, described absorption optical filtering cover glass plated surface infrared cut coating and anti-reflection film, described absorption optical filtering cover glass adds the light absorption materials such as phosphorus pentoxide at melting processing procedure, and described absorption optical filtering cover glass can replace optical filter and cover glass in current image module; Further, in described absorption optical filtering cover glass material, add the light absorption materials such as phosphorus pentoxide, absorb infrared light, through visible ray.
Further, the mass percent of described quartz glass or sapphire glass is 90-99.5%.
Further, the mass percent of the light absorption materials such as described phosphorus pentoxide is 0.5-10%, adopts this ratio to have preferably assimilation effect.
Adopt technique scheme; absorption optical filtering cover glass described in patent of the present invention; effectively can reduce the reflection of light in image module optical system and absorb the halation, ghost, the picture that cause dimmed, the colorshading(aberration that incident light produces because of angle change can be improved) phenomenon.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
