Analysis selects Fabry-Perot Luo (F-P) structure to be designed, and F-P structure is improved based on F-P interference theory.Such as figure
Reflection and projection situation shown in 2, after resonant cavity is entered for incident light, it is assumed that without absorbing state, such as scheme the optical filter resonant cavity
The reflectance coating of two sides indicates that their reflection coefficient and transmission coefficient is expressed as respectively with equivalent interface a and bThe then transmission coefficient of the optical filter are as follows:
In above formula, the position phase thickness of film layer: the π nd/ of δ=2 λ, φa,φbFor the phase of reflectance coating, matched in optical filter two sides
In the identical situation of medium, the transmitance of optical filter are as follows:
By Ta=| ta|2,Tb=| tb|2,Ra=| ra|2,Rb=| rb|2,
It enables
Then have:
Above formula gives the basic representation of F-P bandpass filter transmitance, as θ=2 π, peak transmittance Tmax=
Ts；WhenWhen, peak wavelength positionFor general bandpass filter, Ta=Tb,Ra
=Rb, the peak transmittance of optical filter
By the above process, the corresponding transmissivity of each band logical wave band of more than first bandpass filter of setting and each cut-off region wave
The corresponding transmissivity of section, can determine the specific film layer structure of more than first bandpass filter, optionally, more than first bandpass filter
Film layer sum be 45-65 layer, total physical thickness of film layer is 5000-6000nm.
Preferably, the film layer sum of more than first bandpass filter is 58 layers, when total physical thickness of film layer is 5096.1nm,
The optical filtering efficiency of more than first bandpass filter is preferable, and corresponding more band logical curves are as shown in Figure 3.

Permeable layers.
The band logical wave band number of same more than second bandpass filter of setting, cut-off region number, each band logical wave band are corresponding
Rate and the corresponding transmissivity of each cut-off region wave band are penetrated, can determine the specific film layer structure of more than second bandpass filter, optionally,
The film layer sum of more than second bandpass filter is 45-65 layers, and total physical thickness of film layer is 5000-6000nm, more than second band logical
The film layer sum of optical filter is different from the film layer of more than first bandpass filter sum, and the overall thickness of film layer is not also identical.
Preferably, the film layer sum of more than second bandpass filter is 56 layers, when total physical thickness of film layer is 5049.1nm,
Its filter effect is preferable, and corresponding more band logical curves are as shown in Figure 5.

Wavelength region rate T < 1% of 440nm, 485-520nm, 570-625nm, 700-780nm；410-415nm, 455-470nm, 535-
Wavelength region rate T > 95% of 555nm, 640-685nm, it can be seen that, more than second bandpass filter allows in the embodiment of the present application
The wave band section of transmission is increased compared with the prior art, that is, is allowed the light of more colors to penetrate, improved right eye image lenses in this way
Color and brightness.
More bandpass filters of left eyeglass lens and right eye eyeglass that 3D glasses are constituted it can be seen from Fig. 3 and Fig. 5 allow saturating
The wave band crossed is different, i.e., is separated to the light wave of different wave length, stands so that user can be watched by the 3D glasses
The video and image of body effect.
In addition, a part is reflected, and it is saturating that another part is transmitted to right eye after visible light is incident on more than second bandpass filter
Bright substrate, this is partially transmitted to the light of right eye transparent substrate, needs that right eyeglass lens can be reduced in this way using the second antireflective coating
The optical energy loss of piece.
Specifically, in more than second bandpass filter the second high reflection layer can with material can be Ta2O5、TiO2、H4、ZrO2
Or ZnO, the second low reflection layer are SiO2、MgF2、AlF3Or MgO；The material of the second adhesive layer in second antireflective coating can be

As shown in fig. 6, being the concrete structure schematic diagram of more than second bandpass filter:
It is successively the first high reflection layer Ta from bottom to up on right eye transparent substrate BK72O5, the first low reflection layer SiO2、
First high reflection layer Ta2O5With the first low reflection layer SiO2Deng film layer structure alternate in this way shares 56 layers.
It is successively the second adhesive layer SiO2, spread bandwidth layer TiO under upper under right eye transparent substrate BK72, second
Antireflection layer Mgf2, spread bandwidth layer TiO2With the first antireflection layer SiO2.
The function of second antireflective coating is identical as the function of the first antireflective coating, and structure can identical or not phase
Together, the structure of the first antireflective coating and the second antireflective coating that provide in the embodiment of the present application is identical, to the saturating of each wave band
It is as shown in Figure 7 to penetrate rate curve.
It may be seen in fig. 7 that the requirement of the first antireflective coating and the second antireflective coating is the wave band to 380-780nm
Transmissivity T > 99.5%.
