The utility model content
The purpose of this utility model provides a kind of simple in structure, superior performance, modular multiple light courcess multichannel measuring system, is specifically designed to the device that needs hyperchannel optics to measure.
For achieving the above object, solution of the present utility model is: a kind of multiple light courcess multichannel measuring system, it comprises one and more than one light source, a light source fixed head, one and more than one collimation lens, sample groove, one and more than one condenser lens, one and a more than one detector and a detector fixed head, also has a holder; Light source is fixed in above the light source fixed head, is positioned at the sample cell front, and collimation lens is between light source and sample cell, detector is fixed in above the detector fixed head, be positioned at the sample cell back, condenser lens is between sample cell and detector, and each parts is separately fixed on the holder.
Described light source is the LED solid light source, and five LED solid light sources equidistantly form a line, and are fixed on the light source fixed head.
Described sample cell is provided with five sample cells that are used to place cuvette.
Described detector is a photodetector, and five photodetectors equidistantly form a line, and are fixed on the detector fixed head.
After adopting such scheme, the utility model is after collimating through collimation lens by the light that light source sends, to become directional light, by sample cell, through after the attenuation by absorption of sample, focuses on detector surface by condenser lens, thereby realizes the collection of light signal.Therefore it has following advantage:
One, multiple light courcess multichannel measuring system of the present utility model, simple in structure, superior performance, modularization;
Its two, light source, detector can be changed as required flexibly, to adapt to different testing requirements.
Description of drawings
Fig. 1 is a contour structures synoptic diagram of the present utility model.
Embodiment
As shown in Figure 1, multiple light courcess multichannel measuring system of the present utility model, it comprises one and more than one light source 2, a light source fixed head 1, one and more than one collimation lens 3, sample groove 4, one and more than one condenser lens 6, one and a more than one detector 7 and a detector fixed head 8, also has a holder 9; Light source 2 is fixed in above the light source fixed head 1, it adopts the LED solid light source, five LED solid light sources equidistantly form a line to be separately fixed at and are positioned at sample cell 4 fronts on the light source fixed head 1, each collimation lens 3 is between each light source 2 and sample cell 4, each detector 7 is a photodetector, and five photodetectors equidistantly form a line, and is fixed on above the detector fixed head 8, be positioned at sample cell 4 back, each condenser lens 6 is between sample cell 4 and each detector 7; Have a plurality of sample cells 5 in the sample cell interior 4, be used to place cuvette; Above-mentioned parts all is fixed on above the holder 9.
Ultimate principle of the present utility model: the light that light source 2 sends becomes directional light after collimating through collimation lens 3, by sample cell 4, through after the attenuation by absorption of sample, focuses on detector 7 surfaces by condenser lens 6, thereby realizes the collection of light signal.Simple in structure, the superior performance of feasible system, modular characteristics thus; And light source, detector can be changed as required flexibly, to adapt to different testing requirements.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claims and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
