Description
Technical field
The present invention relates to field of film preparation, a kind of method for designing of smalt optical filter is specifically disclosed.
Background technology
With the development of science and technology, requirement more and more higher of the people to shooting quality, improves an approach of shooting quality just
It is to carry out infrared filtering, cutoff filter is added between camera lens and CCD or cmos image sensor, can effectively suppresses
Light wave higher than CCD or cmos image sensor spatial frequency passes through, and can effectively prevent ripple from disturbing, raising colored CCD,
COMS imageing sensors effective resolution and colour reproduction, become apparent from image, stablize.
In the prior art, cutoff filter typically by the film of multilayer low-index material high in clear optical glass
Surface stacking is formed, and multiple-beam interference ends away to infrared light in Applied Physics optics；Another method is exactly to use
Smalt is substrate, and infrared cut coating is coated with smalt surface, and IR-cut is coordinated by smalt absorption in itself
Film reaches the effect of cut-off infrared waves.But due to smalt in itself material, coating process, plated film is easy on smalt
Fall off, make the infrared fileter structural instability to be formed, short life.
The content of the invention
Based on this, it is necessary to for prior art problem, there is provided a kind of method for designing of smalt optical filter, it is possible to increase
The firmness of smalt plated film, the filter sheet structure for forming plated film is more stablized.
To solve prior art problem, the present invention discloses a kind of method for designing of smalt optical filter, comprises the following steps：
The material for setting substrate is smalt, and contact layer is designed with substrate upper and lower surface, and the material for setting contact layer is lanthanium titanate,
The lower surface of the upper surface of upper contact layer and lower contact layer is designed with composite bed, and composite bed is by high-index material and low-refraction
Material is alternately stacked to be formed.
Further, high-index material is TiO2、Ti3O5、Na2O5Or Nb2O5In one or more.
Further, low-index material is SiO2Or MgF2。
Beneficial effects of the present invention are：The present invention discloses a kind of method for designing of smalt optical filter, can be effectively improved
The firmness of film layer during smalt plated film, prevents smalt optical filter from causing film layer to come off due to material itself, makes
The smalt filter sheet structure of formation is more stablized.
Brief description of the drawings
Fig. 1 is the structural representation that the present invention is made smalt optical filter.
Specific embodiment
It is specific purposes, the function that can further appreciate that feature of the invention, technological means and reached, with reference to
Accompanying drawing is described in further detail with specific embodiment to the present invention.
With reference to Fig. 1.
The present invention discloses a kind of method for designing of smalt optical filter, comprises the following steps：It is indigo plant to set the material of substrate
Glass, contact layer is designed with substrate upper and lower surface, and the material for setting contact layer is lanthanium titanate (H14La2O7Ti2), in upper contact
The upper surface of layer and the lower surface of lower contact layer are designed with composite bed, and composite bed is handed over by high-index material and low-index material
Formed for stacking, it is preferable that high-index material is TiO2、Ti3O5、Ta2O5Or Nb2O5In one or more, low-refraction
Material is SiO2Or MgF2。
The contact layer of traditional smalt optical filter is all traditionally arranged to be SiO2Or TiO2, the material of present invention setting contact layer
It is lanthanium titanate, the adhesive force between smalt and film layer can be effectively improved.First lanthanium titanate is plated as contact layer toward substrate, then
The composite bed with feux rouges filtering function is plated toward contact layer, composite bed is secured firmly on substrate by contact layer,
Plated film is more firm on toward smalt, can effectively improve the stability of smalt optical filter film layer structure, extension smalt filter
The service life of mating plate；Film layer is plated with the upper and lower surface of substrate, the stress that can introduce substrate both sides is approached, Neng Gouyou
Effect prevents substrate from being deformed due to the unequal power distribution of both sides, improves the quality of smalt optical filter.
6 small pieces will be divided into by smalt optical filter obtained in the inventive method, and be put into boiling water and hot plate, it is small every half
When take out a wherein small pieces smalt optical filter carry out membrane test, the 3rd hour take out last small pieces smalt filter
Piece, measures situation of the 6 small pieces smalt optical filters without demoulding and occurs.
The smalt filter sheet structure stabilization formed by the present invention, film ply adhesion is sufficiently large, in particular improves
Smalt substrate surface and the contact force of other film layers, can effectively strengthen the compactness of smalt optical filter, extend smalt
The life-span of optical filter.
Embodiment described above only expresses several embodiments of the invention, and its description is more specific and detailed, but simultaneously
Therefore the limitation to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that for one of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to guarantor of the invention
Shield scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
