Portable Raman spectrometer by laser generator 1, laser mirror 2, optical lens unit 3, spectroscopic detection unit 4 and inspection
Survey device (CCD) 5 composition, according to the particularity of optic path, by laser generator 1, laser mirror 2, optical lens unit 3,
Spectroscopic detection unit 4 and detector (CCD) 5 are mutually combined on a pentagonal prism shape support frame with special construction, and one
Rise and constitute Raman spectrometer, treat detection material and carry out laser irradiation, detect the Raman signal of material to be detected.
But the Portable Raman spectrometer in above-mentioned patent can only be that hand-held spectrometer alignment is to be measured in use
Thing, the problem of hand-held shakiness easily occur and cause analysis result to be forbidden, if spectrometer and determinand are fixed respectively, do not allow
The easily position of adjustment between the two.
Utility model content
In order to solve the above problems, the purpose of this utility model is to provide a kind of portable Raman light for having installation slot
Spectrometer, using the slot, the fixture for fixing determinand can be coordinated to use.
The Portable Raman spectrometer of tool installation slot, includes a shell body, is placed in the shell in the utility model
Internal laser generator, optical lens unit, spectroscopic detection unit and detector, the optical lens unit, which includes, to be used for
Laser exports to the infrared anti-reflection lens that determinand is directed at outside the spectrometer, the infrared anti-reflection lens extend it is described
Two sides of Outer housing component respectively set an installation slot for being in vertical state, corresponding with the installation slot, for fixing
One socket being inverted U shape is set in the fixture of determinand, is respectively formed with and is inserted on two madial walls of the socket
Raised line in the installation slot.
Described two install the center line of slot in the same plane, and two installation slots are in parastate.
The groove width of the installation slot is between 3-8mm, and depth is between 0.5-1.5mm.
The width of the socket is more than the diameter of the infrared anti-reflection lens.
The width of the raised line is identical with the groove width of the installation slot, during processing the installation slot capping processing miss
Difference, the mismachining tolerance that raised line removes the limit.
By extending the setting slot of the infrared anti-reflection lens outer surface outside shell body in the utility model, can coordinate
Use nipper, it is ensured that spectrum analysis is more accurate.
