In addition to this, the narrowband reflection film 32 of the application also has narrowband reflection effect outstanding, is described in detail below:
Since the difference that cosine waveform and sinusoidal waveform are phase generates.In order to express easily, below only with regard to cosine
Waveform is illustrated.Currently in order to realizing narrowband reflection, the prior art is dedicated to increasing high refractive index material layer in reflection membrane system
The selection of design and refractive material with the low refractive index material layer number of plies, present inventor have been surprisingly found that under study for action, when
There are directly related properties for the bandwidth of reflection peak for the thickness change of high refractive index material layer and low refractive index material layer, are based on
This present inventor has made intensive studies the thickness change rule of high refractive index material layer and low refractive index material layer,
And find that the optical thickness coefficient of high refractive index material layer 321 and low refractive index material layer 322 follows the rule of cosine waveform and passs
The cosine membrane stack being deformed into has effect outstanding to the bandwidth for reducing reflection peak.Action principle therein, inventor think:
According to Fabry-Perot (Fabry-Perot) principle of interference, when the frequency of incident light meets its resonance condition,
Its transmission spectrum will appear very high peak value, correspond to very high transmissivity.Assuming that interference strength is distributed:
I in formula0For incident intensity；R is the energy reflectivity of reflecting surface；Phase difference of the δ between adjacent two coherent light, and enters
Penetrate that light inclination angle is related, R+T=1 (R is the surface reflectivity of membrane system, and T is transmissivity).Due between adjacent high refractive index layer
Distance and the distance between adjacent low refractive index material layer that is, the distance of wall, and according to Fabry-Perot
Principle of interference, interference reaches maximum when the distance of wall is the multiple of λ/4, and according to more than the transmission of the duality principle of light
The period of string wave property, cosine becomes larger, therefore is │ (α by the way that film structure is arranged in reflection membrane system1Hβ1Lα2Hβ2L...αmHβmL) the membrane stack of │, due to membrane stack high refractive index material layer and low refractive index material layer optical thickness coefficient (i.e.
α, β) follow the regular alternation of cosine waveform, i.e., the distance between adjacent high refractive index layer and adjacent low-index material
The regular alternation of cosine waveform is presented in the distance between layer, the interference effect of specific wavelength will be made to be enhanced, then right
Respective indices of refraction is answered to form the trend that the wavelength band of interference narrows presentation, i.e. the membrane stack can make reflectivity sharp change occur
Range of light wavelengths largely narrow, to the effect of narrowband reflection occur, then the effect color thus reflected
It is sharp keen, metal-like is presented.It is so integrated to the intelligent shop window system of the application, is reflected using the narrowband reflection film of the application

Rate is NH, the physical thickness of high refractive index material layer 321 is DH, then there is NH *DH=αi*λ/4；Low refractive index material layer 322
Refractive index is NL, the physical thickness of low refractive index material layer 322 is DL, then there is NL *DL=βi*λ/4；Wherein, α1, α2..., αm
And βm..., β2, β1Meet each independently selected from range in the same sinusoidal waveform of 0~2 π and the upper left half of cosine waveform
Same gradation law on string, lower-left semifocal chord, upper right semifocal chord and bottom right semifocal chord.Above-mentioned each optical thickness coefficient is in above range
The waveform changing rule of four semifocal chords of the same string wave is inside followed, the difference of obtained optical thickness is in relatively narrow range
It is interior, above-mentioned narrowband effect can be made preferably to play；It and is not in that half-wave hole common in optical thin film design (is being filtered
Often there is a reflection peak at half of the reflection with central wavelength, generally in bandpass region in the practical preparation of mating plate
Referred to as half-wave hole, also having it is referred to as that the half-wave of optical filter falls).
