As specific embodiment, the tested reagent paper of detection paper matching requirements 7 that the present embodiment provides
And the distance between auxiliary lens 5 is less than or equal to the focal length of auxiliary lens 5, to ensure tested reagent paper 7
By the optical imaging system being made up of with imaging lens 6 auxiliary lens 5 can become clearly as, from
And ensure the accuracy of follow-up detection paper.
As preferred embodiment, auxiliary lens 5 includes at least one eyeglass, auxiliary lens 5
Focal length is 40～55mm.The focal length of the imaging lens 6 that smart mobile phone 2 carries is the least, is less than
4.5mm, thus its amplification is less than 0.045, the developed band of some reagent paper is narrow, such as the examination of gold mark
T band (detection band) of paper and C carries (quality control band) width to be about 2mm, its imaging the slightest
In 90 μm.The picture become the most on a sensor is the least, and imaging resolution is not enough, can cause bigger
Detection error.Therefore, the detection paper device that the present embodiment provides increases by installing auxiliary lens 5 additional
Big focal length, improves amplification, thus is expanded into picture, the analytical error of reduction testing result.
As further preferred embodiment, as it is shown in figure 1, auxiliary lens 5 includes the first eyeglass

Between distance be 2～4.5mm.Ensure that the efficiency of light energy utilization.The light fixture 3 that smart mobile phone 2 carries
Generally use is LED, and the light source that i.e. LED sends is after microlens array 41, quite
In a lot of sub-light sources all in luminescence, and all with out of focus aberration, ratio more uniform so can be formed
Each and every one hot spot, links together, and formation is exactly a uniform area light source the biggest.As preferably
Embodiment, the above-mentioned lenticular length of side is preferably 400 μm, and above-mentioned microlens array is preferably by 20
× 20 above-mentioned lenticule compositions.
As further preferred embodiment, as shown in Figure 6, even optical assembly 4 also includes diffusion sheet
42, diffusion sheet 42 and light fixture 3 are oppositely arranged on the both sides of microlens array 41, are used for compareing
The light that bright assembly 3 sends carries out the evenest light.The light processed through microlens array 41 passes through diffusion again
After sheet 42, due to diffusion sheet 42 scattering, reflect, the optical phenomena such as reflection, can to light source again
Carry out even light, thus the light being radiated on tested reagent paper 7 is the most highly uniform, meet the photograph of detection
Bright demand.
Obviously, above-described embodiment is only for clearly demonstrating example, and not to embodiment party
The restriction of formula.For those of ordinary skill in the field, the most also may be used
To make other changes in different forms.Here without also all of embodiment being given
With exhaustive.And the obvious change thus extended out or variation are still in the guarantor of the invention
Protect among scope.
