Description
Technical field
The utility model is related to field of optical device technology, specially a kind of high-strength abrasion-proof smalt optical filter.
Background technology
Optical filter is the optics of the radiation wave band needed for choosing.One general character of optical filter, is exactly not any
Optical filter can allow the imaging of celestial body to become brighter, because all optical filters can all absorb some wavelength, so that object becomes
Obtain darker.At present, common optical filter is influenceed by shooting angle, and ultraviolet during different angles and infrared point wavelength shift is larger, into
Aberration is different also to become big, easy distortion therewith.Therefore, a kind of it is proposed that high-strength abrasion-proof smalt optical filter.
Utility model content
The purpose of this utility model is to provide a kind of high-strength abrasion-proof smalt optical filter, to solve above-mentioned background technology
The common optical filter of middle proposition is influenceed by shooting angle, and ultraviolet during different angles and infrared point wavelength shift is larger, into aberration
It is different also to become big therewith, the problem of easy distortion.
To achieve the above object, the utility model provides following technical scheme：A kind of high-strength abrasion-proof smalt optical filter,
Including smalt substrate, magnesium fluoride film is provided with the top and bottom of the smalt substrate, magnesium fluoride film described in bottom
Bottom is provided with the top of the second filter coating, the top magnesium fluoride film and is provided with the first filter coating, first filter coating
Top is provided with wear Protection film.
It is preferred that, first filter coating and the second filter coating are repeatedly alternately folded by titanium dioxide film and silicon dioxide film
Plus form.
It is preferred that, total number of plies of titanium dioxide film and silicon dioxide film is 20 layers in first filter coating, and titanium dioxide
Titanium film and silicon dioxide film are respectively 10 layers.
It is preferred that, total number of plies of titanium dioxide film and silicon dioxide film is 22 layers in second filter coating, and titanium dioxide
Titanium film and silicon dioxide film are respectively 11 layers.
It is preferred that, the wear Protection film is diamond film.
Compared with prior art, the beneficial effects of the utility model are：The filter coating of utility model first had both had infrared
The function of cut-off, the function with increase translucency, meanwhile, the second filter coating had both had the function of IR-cut, had again
Increase the function of translucency, therefore do not interfere with the optical characteristics of smalt optical filter, wear Protection film rises to the first filter coating
To protective effect, one can be entered by increasing the magnesium fluoride film at the top and bottom of the anti-wear performance of smalt optical filter, smalt substrate
Step increase translucency, because the position difference of two beam reflected lights of two groups of magnesium fluoride films is precisely two, all reflected lights are superimposed
As a result reflection cancellation can be realized, thus forms transmission enhancing；The utility model can effectively amputate infrared and ultraviolet spuious
Light, is not likely to produce imaging interference problem, can be widely applied for mobile phone camera, notebook front camera and high-resolution essence
The close first-class imaging system of monitoring camera, and the requirement of high-accuracy camera system can be met.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
In figure：1 smalt substrate, 2 magnesium fluoride films, 3 first filter coatings, 4 wear Protection films, 5 second filter coatings.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Referring to Fig. 1, the utility model provides a kind of technical scheme：A kind of high-strength abrasion-proof smalt optical filter, including
Smalt substrate 1, it is characterised in that：The top and bottom of the smalt substrate 1 are provided with magnesium fluoride film 2, described in bottom
The bottom of magnesium fluoride film 2 is provided with the second filter coating 5, and the top of the top magnesium fluoride film 2 is provided with the first filter coating 3, institute
The top for stating the first filter coating 3 is provided with wear Protection film 4.
Wherein, the filter coating 5 of the first filter coating 3 and second is repeatedly alternately folded by titanium dioxide film and silicon dioxide film
Plus form, total number of plies of titanium dioxide film and silicon dioxide film is 20 layers in first filter coating 3, and titanium dioxide film and two
Silicon oxide film is respectively 10 layers, and total number of plies makes the first filter coating 3 both have the function of IR-cut, has increase translucency again
Function, total number of plies of titanium dioxide film and silicon dioxide film is 22 layers in second filter coating 5, and titanium dioxide film and two
Silicon oxide film is respectively 11 layers, and total number of plies makes the second filter coating 5 both have the function of IR-cut, has increase translucency again
Function, the wear Protection film 4 be diamond film, diamond film have higher wearability and hardness, excellent electric insulation
Performance.
Operation principle：First filter coating 3 had both had the function of IR-cut, had the function of increase translucency again, meanwhile,
Second filter coating 5 had both had the function of IR-cut, had the function of increase translucency again, therefore did not interfered with smalt optical filtering
The optical characteristics of piece, 4 pair of first filter coating 3 of wear Protection film plays a protective role, and increases the anti-wear performance of smalt optical filter,
The magnesium fluoride film 2 of the top and bottom of smalt substrate 1 can further increase translucency, due to two beams of two groups of magnesium fluoride films 2
The position difference of reflected light is precisely two, and the superimposed result of all reflected lights can realize reflection cancellation, thus form transmission increasing
By force, the utility model can effectively amputate infrared and ultraviolet veiling glare, be not likely to produce imaging interference problem, being capable of extensive use
In the first-class imaging system of the accurate monitoring camera of mobile phone camera, notebook front camera and high-resolution, and it can meet high-precision
The requirement of close camera system.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out in the case where not departing from principle of the present utility model and spirit a variety of changes, repaiies
Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
