Embodiment
One kind strengthens tempering filter, including substrate 110 and film layer 120, and the film layer 120 is by Al2O3The dielectric of composition
Layer and by TiFor the metallic diaphragm of composition by what is be alternately stacked to form, the film layer 120 is attached to the surface of substrate 110；Institute
Film layer 120 is stated to be attached only to the single side surface of substrate 110 or be attached to the both side surface of substrate 110 simultaneously；The substrate 110
It is to be made using chemically toughened glass.
Referring to Figures 1 and 2, a kind of overall construction drawing for two kinds of different embodiments for strengthening tempering filter of the present invention.Full
In the case of sufficient filter filtering light, the position form that the film layer 120 is attached to substrate 110 has two kinds, one of which such as Fig. 1
Shown, the film layer 120 is attached only to the single side surface of substrate 110, is coated with for one side；Another is as shown in Fig. 2 the film
Layer 120 is attached to the both side surface of substrate 110 simultaneously, is double coated.The substrate 110 is made using chemically toughened glass
Form, hardness is strong, so that the resistance to physical strength that falls of filter is improved, is different from resin film, resin plate and simple glass
Thin plate.
One kind strengthens tempering filter, and total number of plies of the dielectric layer and metallic diaphragm includes 5-15 layers, and in film layer 120
First layer be dielectric layer, first layer is attached to the surface of substrate 110.In addition, the thickness of each layer of different parts is protected
Hold the trend that consistent or each layer of thickness shows linear decrease from one end to the other end.When dielectric layer and metallic diaphragm
The total number of plies difference when, each layer of thickness in film layer 120 can change, when double coated, in both sides film layer 120
The thickness of metallic diaphragm is the half that thickness is corresponded to when one side is coated with, the thickness and one side of the dielectric layer in both sides film layer 120
Corresponding consistency of thickness when being coated with.Meanwhile when double coated, film layer 120 is attached to the both side surface of substrate 110, base simultaneously
The thickness of the both sides film layer 120 of piece 110 shows symmetrical structure distribution centered on substrate 110.
Reference picture 3 and Fig. 4, a kind of two kinds of differences for strengthening tempering filter of the present invention apply the structure chart of film layer 120 of example；It is described

(ND), major function is filtering light, reduces thang-kng amount, the increase time for exposure, is usually used in shooting dynamic virtualization scene；
When the thickness of each layer of the film layer 120 shows the trend of linear decrease from one end to the other end, the filter
Mirror is middle grey the Graduated Filter (GND), has fade effect, is mainly used in balancing light ratio, makes dark portion in picture and high light portion equal
Rationally exposure, suitable for big light than environment, such as shooting the scene at sunrise and dusk.
For middle grey filter (ND) and middle grey the Graduated Filter (GND), the metallic diaphragm and electricity of the middle grey filter (ND) are situated between
The thickness one of the thickest part of corresponding metallic diaphragm and dielectric layer in the thickness of matter layer and middle grey the Graduated Filter (GND)
Cause, shown in list lattice specific as follows, list when one side is coated with film layer 120, total number of plies of dielectric layer and metallic diaphragm is 5
Layer, 7 layers, the thickness distribution situation of 9 layers and 11 layers.The filter be by control gear reach dim light or balance light than effect
