Description
Technical field
The utility model relates to the high camera substrate of a kind of transmittance.
Background technology
Modern number code product uses CCD (Charge Couple Device) or CMOS (ComplementaryMetal-Oxide Semiconductor) device, and its sensitive volume comprises visible ray, region of ultra-red.And infrared light can cause the colour temperature deviation of picture and acutance to decline.Simultaneously when using CCD or cmos image sensor to take colored scenery, because they are different from human eye to the reaction of color, for the reaction to color in adjustment visible-range, the color that image is presented meets the sensation of human eye, must between CCD and camera lens module installation infrared cutoff filter (lens surface plating IR-CUT film), thus " filtration " falls infrared light.Cutoff filter also can increase contrast and the resolution of infrared imaging in infrared lens.
The reflection of optical element surface, not only affects the logical luminous energy of optical element; And these reflected light also can form parasitic light in instrument, affect the image quality of optical instrument.In order to address these problems, certain thickness multilayer film on the plated surface of optical element usually, object is the reflected light in order to reduce element surface, and such film is optical anti-reflective film (or antireflective film, i.e. AR film).Generally, when light is incident on the optical element of given material surperficial, the reflected light produced and transmitted light energy are determined, when not considering other factors such as absorption, scattering, the gross energy of reflected light and transmitted light equals the energy of incident light.And the effect of institute's plated film makes the energy of reflected light and transmitted light redistribute.For anti-reflection film, the result of distribution makes the energy of reflected light reduce, and the energy of transmitted light increases.
Utility model content
The purpose of this utility model is to provide a kind of average transmittance of visible region that makes to reach more than 95% for the deficiencies in the prior art, and little on the transmissivity impact in IR-cut district, the camera substrate that lower-cost transmittance is high.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The camera substrate that transmittance is high, comprises lens substrate, and the one side of described lens substrate is coated with IR-CUT film, and another side is coated with AR film.
The thickness of described AR film is about 450 ~ 500nm, and the thickness of IR-CUT film is about 5000 ~ 5500nm.
Described IR-CUT film is by multilayer SiO
2layer and Nb
2o
5layer circulation superposition is formed.
Described AR film is by multilayer SiO
2layer and SI
3n
4layer circulation superposition is formed.
Described AR rete number is 6 ~ 9 layers, and the thickness of IR-CUT film is 60 ~ 90 layers.
Due to adopt such scheme camera substrate one side plate IR-CUT another side plate AR film can make the average transmittance of visible region (380nm-780nm wave band) that more than 95% can be reached (all there is the distinctive reflection of material on camera baseplate material two sides, reach corresponding surface reflection energy by substrate plating surface antireflecting film to lower, reach anti-reflection effect, IR-CUT membrane interaction is simultaneously increasing visible light transmissivity cut-off infrared light in addition), and the transmissivity of IR-cut district (900-1100nm wave band) does not almost affect (being all less than 2% before plating AR film with after plating AR film), and adopt this infrastructure cost lower, efficiency is high, and very easily apply, there is larger marketable value.
Accompanying drawing explanation
Fig. 1 is the structural representation of this patent.
Embodiment
Below by example, further describe the embodiment of this patent.
As shown in Figure 1, the camera substrate that a kind of transmittance is high, comprises camera lens substrate 1, camera lens substrate 1 one side be coated with IR-CUT film 2, another side is coated with AR film 3, described IR-CUT film 2 for ground floor be SiO
2, the second layer is Nb
2o
5, circulate successively, AR film 3 ground floor is SiO
2, the second layer is SI
3n
4, circulate successively.In this example, described IR-CUT film has 79 layers, and described AR film has 9 layers.
