Wherein, H and L represent respectively TiO
2rete (high-index material layer) and SiO
2a 1/4 wavelength optical thickness of rete (low refractive index material layer), TiO
2the refractive index Hn=2.288 that rete is corresponding, SiO
2the refractive index Ln=1.471 that rete is corresponding.This routine medium wavelength λ=365nm, 1H=1/4 λ Hn; 1L=1/4 λ Ln.Coefficient before H and L represents the multiple of 1/4 wavelength.
As shown in Figure 2, near infrared 3D detection filter described in the utility model, at wavelength 828nm, light vertical sand shooting is fashionable, allow the light of 828 ± 7nm wavelength to pass through, and the light of other wavelength is isolated, i.e. cut-off, transmitance T >=90%, the cut-off degree of depth of other wavelength is greater than 3dB, has realized the detection filter of a kind of high permeability near infrared light region and the high cut-off degree of depth.
Although embodiment of the present utility model is open as above, but it is not restricted to listed utilization in instructions and embodiment, it can be applied to the various fields of the present utility model that are applicable to completely, for those skilled in the art, can easily realize other modification, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend of describing.
