Through the holophote piece with light reflection to the sample pipe directly over, will receive optic fibre and the sample pipe structure that is connected of the side of tip down, under the prerequisite that the intensity of having guaranteed the signal detected in batches, reduced exciting optic fibre, messenger's structure is simpler, effectively improved to excite the light intensity, simple to operate, the practicality is strong.
Description
Technical field
This utility model relate to a kind of fluorescence detection device, belongs to technical field of optical detection。
Background technology
Fluoroscopic examination is a kind of conventional detection technique, is utilize analyte to excite the lower characteristic that can produce fluorescence that it is carried out qualitative and quantitative analysis at special wavelength light。This method is not only convenient, fast, is generally also provided with higher sensitivity and selectivity, is therefore widely used in real time and in situ detection。
But existing fluorescence detection device is a kind of is the structure adopting top to excite, and it has the drawback that signal is more weak；The second is the structure adopting side to excite, and owing to optical fiber is all drawn from the side, causes that the space taken is bigger, it is impossible to realize big flux and detect simultaneously。
The patent No. of our company's earlier application is: the structure adopted in the utility model patent of 2015205896256, although can either ensure that signal intensity can realize again batch detection, however it is necessary that and be adopted as each sample tube preparation excitation fiber, when mounted comparatively inconvenience, and practicality is not strong yet。

Detailed description of the invention
Below in conjunction with Figure of description, this utility model is described further。
As shown in Figure 1, a kind of fluorescence detection device, including multiple sample tube 1, light source 2, photoelectric gathering apparatus 6, it is provided with for light being reflexed to the total reflection eyeglass 4 directly over sample tube 1 between described sample tube 1 and light source 2, it is connected to the reception optical fiber 5 consistent with described sample tube 1 quantity between described sample tube 1 and photoelectric gathering apparatus 6, and one end correspondence of described reception optical fiber 5 is connected to the side of described sample tube 1 bottom。
Sample tube 1 adds the reagent of about 0.2ml, the light produced by light source 2 by being totally reflected eyeglass 4 shines from the surface of sample tube 1, by receiving the structure that optical fiber 5 is connected with the side of sample tube 1 bottom, both ensure that the intensity of signal, and be capable of batch detection。
And replace optical fiber by being totally reflected eyeglass 4, not only cost reduces, and overall structure is simpler, easier for installation, and practicality is higher。
Simultaneously, the surface of each sample tube 1 is additionally provided with lens 7, for focused activating light, to improve the intensity of exciting light, it is irradiated to bottom sample tube 1 by lens 7 after the light focusing after total reflection eyeglass 4 reflects, ensure that the uniformity of light source, it is to avoid sample tube 1 is directly irradiated by light, cause that because of edge effect the situation of deviation occurs in testing result。
Meanwhile, between described total reflection eyeglass 4 and light source 2, between described reception optical fiber 5 and photoelectric gathering apparatus 6, it is provided with multi-channel filter 3, it is simple to adopt the light source of multiple different wave length to detect。
In the present embodiment, described light source 2 is the one in LED, xenon lamp, Halogen light, and described reception optical fiber 5 is the ordinary optic fibre of diameter of 1 mm-3 mm。
In sum, a kind of fluorescence detection device that this utility model provides, under ensureing the premise of signal intensity and batch detection, simplify structure, easy for installation, practical。
Of the present utility model ultimate principle, principal character and advantage have more than been shown and described。Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description is that principle of the present utility model is described; under the premise without departing from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements both fall within the scope of claimed this utility model。This utility model claims scope by appending claims and equivalent circle thereof。
