Incident optical 2-1, collimation convex lens 2-2, optical filter 2-3, back transmission one side it has been sequentially arranged back to front anti-in road 2
Penetrate dichroic mirror 2-4, focussed collimated convex lens 2-5；And Raman scattering is respectively arranged in collecting passage 3 the most successively
There are collection optical fiber 3-1, focussed collimated convex lens 3-2, high pass laser filter plate 3-3, reflecting mirror 3-4.
Further, it is internal that incident laser is input to laser channeling 2 from rear portion through incident optical, through collimation convex lens
Light is collimated by 2-2, after optical filter 2-3, filters off the veiling glare in laser, then reflects two by back transmission one side
To color mirror 2-4 by Laser Transmission to probe interface, after the focussed collimated convex lens 2-5 of interface, it is thus achieved that focal length is
The focusing laser of 7.5mm, is irradiated to detect sample 4 surface.
Detection sample 4 through laser irradiate after send Raman scattering, Raman scattering through focussed collimated convex lens 2-5 collect,
After collimation, it is irradiated to back transmission one side reflection dichroic mirror 2-4, back transmission one side reflection dichroic mirror 2-4 and Raman is dissipated
Penetrating the reflecting mirror 3-4 reflexing to be positioned above, Raman scattering is reflexed to high pass laser filter plate 3-3 by reflecting mirror 3-4 again,
The bias light collected, veiling glare etc. are filtered by high pass laser filter plate 3-3, and remaining Raman scattering, Raman scattering is led to again
After over-focusing collimation convex lens 3-2, it is transferred to gather in optical fiber 3-1.
Described incident laser and Raman scattering are collected and are all used same focussed collimated convex lens 2-5, focussed collimated convex lens
2-5 be focal length be the sapphire lens of 7.5mm.The coating of described optical lens surface is formed avoids ambient to bring
Noise, the nano coating of enhancing optical signal.
The beneficial effects of the utility model are:
1, integral type dual pathways Raman spectrum acquisition probe realize Raman spectrometer laser send and Raman scattering signal collect
Integration, simplifies Laser emission and the device of Raman scattering collection, is greatly simplified Raman spectrometer parts, it is achieved collection
Cheng Hua, volume is little, lightweight.
2, solve conventional laser and send the difficult problem interfered with each other with Raman scattering collection.
3, on optical glass, it is coated respectively with special nano coating, by fine vacuum surface spraying technique, at optics
Lens surface forms the nano coating strengthening optical signal effect；Form fabulous permeability and noise control surface, it is possible to keeping
On the basis of Raman scattering signal is maximized, filter unnecessary noise, keep the degree of purity of Raman scattering signal.
4, integral type dual pathways Raman spectrum acquisition probe can be integrated into inside Raman spectrometer, it is possible to use optical fiber is even
Receive outside Raman spectrometer, variation signals collecting, meet multiple occasion and use.

Detailed description of the invention
Seeing Fig. 1 and Fig. 2, the integral type dual pathways Raman spectrum acquisition probe of the present embodiment, its detection part uses straight
The cylinder of footpath 9.5mm, a length of 25mm, it is possible to be suitable for varying environment occasion, as goed deep into bottle interior detection etc..
The body shell 1 of acquisition probe is in cuboid, and housing 1 uses has the alloy material that photopermeability is zero, can disappear
Impact Raman scattering caused except ambient.It is provided with two passages being parallel to each other in housing 1, is arranged in respectively
Passage 3 is collected in the laser channeling 2 of bottom and the Raman scattering being arranged in top.
Wherein, incident optical 2-1, collimation convex lens 2-2, tool it are respectively disposed with in laser channeling 2 the most successively
The optical filter 2-3 of face coat, back transmission one side is had to reflect dichroic mirror 2-4, focussed collimated convex lens 2-5；Incident sharp
It is internal that light is input to laser channeling 2 through incident optical 2-1, is collimated by light through collimation convex lens 2-2, through filtering
After mating plate 2-3, the veiling glare in laser is filtered off, by back transmission one side reflection dichroic mirror 2-4 by Laser Transmission extremely
Probe interface, after the focussed collimated convex lens 2-5 of interface, it is thus achieved that focal length is the focusing laser of 7.5mm, is irradiated to
Detection sample 4 surface.
Detection sample 4 sends Raman scattering after laser irradiates, and Raman scattering is redirected back into focussed collimated convex lens 2-5,
After focussed collimated convex lens 2-5 collection, collimation, it is irradiated to back transmission one side reflection dichroic mirror 2-4, back transmission
Raman scattering is reflexed to the reflecting mirror 3-4 being positioned above by one side reflection dichroic mirror 2-4, and thus, Raman scattering is entered
Enter Raman scattering and collect passage 3.
In passage 3 is collected in Raman scattering, Raman scattering is reflexed to high pass laser filter plate 3-3 by reflecting mirror 3-4 again,
The bias light collected, veiling glare etc. are filtered by high pass laser filter plate 3-3, and remaining Raman scattering, Raman scattering is led to again
After over-focusing collimation convex lens 3-2 collimation, it is transferred to gather in optical fiber 3-1, it is achieved Raman spectrum collection.
The incident laser of this probe and Raman scattering are collected and are used same focussed collimated convex lens 2-5, focussed collimated convex lens
Mirror 2-5 uses focal length to be the sapphire lens of 7.5mm, and lens surface is coated with nano coating, can be prevented effectively from ambient light
The noise that tape comes.Internal each optical lens, is coated respectively with nano coating, by fine vacuum surface on optical glass
Spraying technique, forms the nano coating strengthening optical signal effect at optical lens surface；Form fabulous permeability and noise control
Surface, it is possible on the basis of keeping Raman scattering signal maximized, filter unnecessary noise, keep Raman scattering signal
Degree of purity.
