Abstract
The utility model discloses a kind of infrared light optical filter, comprise smalt substrate, magnesium fluoride tack coat and infrared cut of light layer, described smalt substrate, magnesium fluoride tack coat, infrared cut of light layer are fitted fixing successively, described smalt substrate, magnesium fluoride tack coat, infrared cut of light layer are provided with breach at correspondence position, described infrared cut of light layer is bonded by titanium oxide layer and silicon dioxide layer, silicon dioxide layer is positioned at the top of titanium oxide layer, and the upper surface of described silicon dioxide layer is provided with the gradient, the gradient of silicon dioxide layer upper surface is 5 degree.The utility model translucidus and infrared cut of light effect excellent, and this optical filter not easily assembles water smoke.
Description
Technical field
The utility model relates to mobile phone camera component technology field, is specifically related to a kind of infrared light optical filter.
Background technology
In the composition structure of camera, often need to relate to infrared fileter.By arranging the infrared portions filtering that human eye cannot detect by infrared fileter, adjusting in visible-range simultaneously and the best visual effect is reached to the color that the reaction of color makes image present, greatly improving picture quality.In the prior art, the design of infrared fileter has the following disadvantages: adopt PVC as the base material of infrared fileter, translucidus difference and infrared cut of light weak effect; In addition, the outside surface of infrared fileter is surface level, and produce water smoke once infrared fileter, water smoke concentrates on the zone line of camera lens, not easily spreads.
Utility model content
The purpose of this utility model overcomes weak point of the prior art, provide a kind of translucidus and the excellent infrared fileter of infrared cut of light effect, and this optical filter not easily assembles water smoke.
The purpose of this utility model is achieved through the following technical solutions:
A kind of infrared light optical filter, comprise smalt substrate, magnesium fluoride tack coat and infrared cut of light layer, described smalt substrate, magnesium fluoride tack coat, infrared cut of light layer are fitted fixing successively, described smalt substrate, magnesium fluoride tack coat, infrared cut of light layer are provided with breach at correspondence position, described infrared cut of light layer is bonded by titanium oxide layer and silicon dioxide layer, silicon dioxide layer is positioned at the top of titanium oxide layer, and the upper surface of described silicon dioxide layer is provided with the gradient, the gradient of silicon dioxide layer upper surface is 5 degree.
The utility model has the following advantages and beneficial effect compared to existing technology:
(1) the utility model utilizes smalt to instead of the base material of traditional PVC as optical filter, improves light transmission.
(2) this practicality is provided with and improves the cut-off effect of infrared light by arrange the alternately infrared cut of light layer that forms of titanium oxide layer and silicon dioxide layer on smalt substrate, and the setting of magnesium fluoride tack coat adds the adhesion between infrared cut of light layer and smalt substrate.
(3) gradient of the utility model also by silicon dioxide layer upper surface being arranged 5 degree, makes the water smoke that optical filter is assembled more easily spread.
(4) the utility model also carries out fool proof by arranging breach on optical filter, reduces the risk that filter set is anti-loaded.
Accompanying drawing explanation
Fig. 1 is the utility model infrared light filter sheet structure schematic diagram.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but the embodiment that the utility model is created is not limited thereto.
Embodiment
As shown in Figure 1, a kind of infrared light optical filter, comprises smalt substrate 1, magnesium fluoride tack coat 2 and infrared cut of light layer, and smalt substrate 1, magnesium fluoride tack coat 2, infrared cut of light layer are fitted fixing successively.Wherein, infrared cut of light layer is bonded by titanium oxide layer 31 and silicon dioxide layer 32, and silicon dioxide layer 32 is positioned at the top of titanium oxide layer 31.On optical filter, easily assemble water smoke, inventor is provided with the gradient at the upper surface 321 of silicon dioxide layer, makes silicon dioxide layer upper surface 321 be 5 degree relative to the angle that silicon dioxide layer lower surface 322 tilts.In addition, in order to reduce the anti-loaded risk of filter set, in the specific implementation, also at smalt substrate 1, magnesium fluoride tack coat 2, titanium oxide layer 31, silicon dioxide layer 32 correspondence position is provided with breach 4.
The above embodiment only have expressed the embodiment of utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
Claims (1)
1. an infrared light optical filter, it is characterized in that: comprise smalt substrate, magnesium fluoride tack coat and infrared cut of light layer, described smalt substrate, magnesium fluoride tack coat, infrared cut of light layer are fitted fixing successively, described smalt substrate, magnesium fluoride tack coat, infrared cut of light layer are provided with breach at correspondence position, described infrared cut of light layer is bonded by titanium oxide layer and silicon dioxide layer, silicon dioxide layer is positioned at the top of titanium oxide layer, and the upper surface of described silicon dioxide layer is provided with the gradient, the gradient of silicon dioxide layer upper surface is 5 degree.
