Embodiment
See also shown in Figure 1ly, a kind of confocal fluorescent pick-up unit of the utility model mainly comprises spectroscope 1, excitation source 2, microcobjective 3, chip microchannel 4 and detecting device 5.
Wherein, spectroscope 1 can reflect exciting light and transmission fluorescence, its role is to make the emission light of excitation source 2 to be reflected and can not see through, and the fluorescence of longer wavelength then can major part see through, thereby eliminates the interference of strong exciting light to fluoroscopic examination effectively.
The transmit direction of excitation source 2 is towards spectroscope 1.
Microcobjective 3 is arranged on the reflection direction of spectroscope 1.
Be distributed with fluorescent material in the chip microchannel 4, be divided into the both sides of microcobjective 3 with spectroscope 1.Preferable, chip microchannel 4 is arranged on the focus place of microcobjective 3.
Detecting device 5 is arranged on the transmission direction of spectroscope 1.
In addition, emission light optical filter 6 also can be set between excitation source 2 and spectroscope 1, and between spectroscope 1 and detecting device 5, be provided with exciting light optical filter 7.Exciting light optical filter 7 is preferably bandpass filter, and only the fluorescence for specific band sees through, to reduce the ground unrest of detecting device.
Be the basic light path of the utility model confocal fluorescent pick-up unit shown in Fig. 1 arrow: the exciting light that sends from excitation source 2 is after 6 filtering of emission light optical filter, reflected by dichroic beam splitter 1, focus in the chip microchannel 4 by microcobjective 3 again, send the fluorescence of respective wavelength to excite fluorescent material in the microchannel 4; Fluorescence is collected by same object lens 3, see through dichroic beam splitter 1 after, by exciting light optical filter 7 elimination parasitic lights, enter detecting device 5 at last and be converted into electric signal.Because the focusing of exciting light and the collection of fluorescence are all finished by same microcobjective 3, and exciting light focal beam spot and diaphragm be in respectively on two conjugate focuses, so be referred to as common focus type detecting device.
