Description
Technical field
The utility model is related to optical element technology field, more particularly to a kind of absorption ultraviolet infrared filtering of day and night
Piece.
Background technology
Visible ray seen by human eye, its wave-length coverage be 390 to 760 nanometers between, it is referred to as ultraviolet less than 390 nanometers
Light, is referred to as infrared light, ultraviolet light and infrared light human eye can not be seen higher than 760 nanometers.Common photograph, picture pick-up device
In the environment without light source, because no visible ray can not obtain image, but use special optical filter, can catch in the evening
Grasp the light that human eye be can't see, such as ultraviolet light, infrared light etc., it is possible to more clearly image is obtained, so needing late
The picture pick-up device of upper work, such as monitoring camera, it is general using two kinds of different optical filters, it can automatically switch, respectively white
It and evening use.
The content of the invention
The utility model be in order to solve the optical filter evening on daytime of prior art can not be general the problem of there is provided one kind knot
Structure is simple, easy to use, and without switching, more picture rich in detail can be obtained on daytime and evening using same optical filter
The absorption ultraviolet infrared fileter of day and night.
To achieve these goals, the utility model uses following technical scheme：The absorption ultraviolet infrared absorption filter of day and night
Mating plate, including substrate, described substrate side plate face are provided with ink layer, and described ink layer is infrared absorbing inks layer, institute
State the two sides of another lateral plates of substrate, ink layer lateral surface upper individually or jointly provided with multiple film plating layers, described plating
The film layer number of plies is 1-100 layers.The infrared absorbing inks used in this programme is existing products, and infrared absorbing inks are only to infrared waves
A part of wavelength period in section is ended, therefore this programme also makes non-barrier portion specific wavelength in infrared band by plated film
The light wave of section passes through, specific visible accompanying drawing 4；When this programme product is used in optics module, daytime normally uses, and in evening
On, due to allow for passing through for infrared part specific wavelength, it becomes possible to clearly catch portrait at night；With it is enterprising in substrate merely
The product of row plated film compares the ink layer due to adding infrared absorption effect, and (50% is saturating for half value when angle of incidence of light degree changes
Cross wavelength during rate) variable quantity it is small, picture quality is more preferable；Compared with the product using heat absorbing glass, due to infrared suction
It is that whole infrared part wavelength is ended to receive glass, therefore it can not realize night vision effect.
Preferably, described substrate is glass plate or crystal slab.This programme meaning glass plate or crystal slab are light
Glass plate or optics crystal slab are learned, the substrate of both materials can be realized preferably is coated with infrared absorption oil in its plate face
Ink and progress coating film treatment.
Preferably, described film plating layer uses titanium oxide, silica, aluminum oxide, zirconium oxide, H4, magnesium fluoride, tantalum oxide
In one or more.Existing plated film layer material is a lot, and the material that this programme is used, which can be realized, makes infrared absorbing inks not
The light wave of part specific wavelength section passes through in the infrared band of cut-off, and wherein H4 is industry proprietary material.
Daytime and evening can be achieved after coating (infrared absorbing inks layer) glass and common white glass sheet plated film of this programme
On switching, but the coating glass of this programme has the following advantages that than blank glass：1st, light blank glass plating when tilting (30 °)
Film rear center wavelength shift ＞ 20nm, coating glass then plated film rear center wavelength shift ＜ 10nm, use the image of coating glass
Better quality；2nd, coating glass is absorption-type material and blank glass then non-absorbing section bar material, the absorption-type material of coating glassMakeImaging portrait high definition when taking pictures, in vainPlateGlass is unable to reach this effect.
Therefore, the utility model has the advantages that：(1) it is simple in construction, it is easy to use；(2) without switching, use
Same optical filter can obtain more picture rich in detail on daytime and evening.
