A kind of camera lens filter sheetTechnical field
The utility model relates to a kind of camera lens filter sheet, and a kind of especially have a camera lens filter sheet anti-reflection, water-proof function.
Background technology
At present, glass mirror is one of main accessory of the electronic products such as mobile phone, MP4, camera, computer, especially camera glass mirror, function film on a vacuum plating of glass substrate normally, such as anti-reflective film, spectro-film, filter coating etc. to finish desired function; But eyeglass commonly used all is the functional membrane of electroplating simple function, and the poor effect that can realize, and lacks the waterproof and dustproof function, when camera lens is stained with water droplet, water droplet can automatic sliding under, must wipe with absorbent cloth, affect people's effect of taking a picture.
Summary of the invention
In order to overcome the deficiency of existing capability technology, the utility model provides a kind of camera lens filter sheet anti-reflection, water-proof function that has.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of camera lens filter sheet comprises glass substrate, it is characterized in that the diaphragm that all is coated with successively multi-layered antireflection coating and has waterproof and dustproof, damage resistant function on two surfaces of described glass substrate; Described multi-layered antireflection coating comprises middle refractive index coating materials layer, the high refractive index film bed of material and the low refractive index film bed of material successively.
The beneficial effects of the utility model are: the diaphragm that all is coated with successively multi-layered antireflection coating on two surfaces of the utility model glass substrate and has waterproof and dustproof, damage resistant function, can not only increase the transmittance of eyeglass, and can prevent effectively that lens surface from being polluted by foul, grease proofing, waterproof, damage resistant reduces the reflectivity of eyeglass simultaneously, keeps the sharpness of eyeglass form; In addition, the setting of diaphragm can be eliminated the stress that exists between the multi-layered antireflection coating of glass substrate single face, and optical property is improved, and is widely used on the lens wearer of camera.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of the preferential embodiment of the utility model.
Embodiment
With reference to Fig. 1, a kind of camera lens filter sheet of the utility model embodiment comprises glass substrate 1, it is characterized in that the diaphragm 3 that all is coated with successively multi-layered antireflection coating 2 and has waterproof and dustproof, damage resistant function on two surfaces of described glass substrate 1.Described multi-layered antireflection coating 2 comprises middle refractive index coating materials layer, the high refractive index film bed of material and the low refractive index film bed of material successively.Certainly, any one deck available equivalents layer of anti-reflection film 2 realizes that film system extends more multi-layeredly, and what of the number of plies are decided according to the demand of product.
The anti-reflection film 2 of present embodiment is typical anti-reflection film structure, the mixed oxide material of refractive index during middle refractive index coating materials layer adopts, and the high refractive index film bed of material adopts the high index of refraction mixed oxide.The coating materials of diaphragm 3 adopts the grease proofing membrane granule material of high-purity to make.
Above-mentioned is the basic structure of the utility model embodiment.
In sum; the diaphragm 3 that all is coated with successively multi-layered antireflection coating 2 on two surfaces of the utility model glass substrate 1 and has waterproof and dustproof, damage resistant function can not only increase the transmittance of eyeglass, and can prevent effectively that lens surface from being polluted by foul; grease proofing; waterproof, damage resistant reduces the reflectivity of eyeglass simultaneously; the sharpness that keeps the eyeglass form; when water droplet drops on the eyeglass, the automatic landing of water droplet meeting, lens surface does not stay any vestige.In addition, the setting of diaphragm 3 can be eliminated the stress that exists between the multi-layered antireflection coating 2 of glass substrate 1 single face, and optical property is improved, and is widely used on the lens wearer of camera.
The above has carried out exemplary description to specific embodiment of the utility model by reference to the accompanying drawings, and obviously the utility model is not limited to this, and the details of other not specified (NS) is also in protection domain of the present utility model.
