Portable Raman spectrometer by laser generator 1, laser mirror 2, optical lens unit 3, spectroscopic detection unit 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 and detector (CCD) 5 are mutually combined on a pentagonal prism shape support frame with special construction, together
Raman spectrometer is constituted, treating detection material carries out laser irradiation, detects the Raman signal of material to be detected.
But the Portable Raman spectrometer in above-mentioned patent can only be in use that hand-held spectrometer alignment is to be measured
Thing, easily occurs hand-held unstable and causes the inaccurate problem of analysis result, if spectrometer and determinand are fixed respectively, does not allow
Easily adjust position between the two.
The content of the invention
In order to solve the above problems, it is an object of the invention to provide a kind of Portable Raman optical spectrum for having and installing slot
Instrument, using the slot, can coordinate and be used for fixing the fixture of determinand.
Have the Portable Raman spectrometer for installing slot in the present invention, include a shell body, be placed in the shell body
Laser generator, optical lens unit, spectroscopic detection unit and detector, the optical lens unit included for that will swash
Optical transport goes out outside the spectrometer to be aligned the infrared anti-reflection lens of determinand, and the infrared anti-reflection lens are extending the shell
Two sides of body portion respectively set an installation slot for being in vertical state, corresponding with the installation slot, to be measured for fixing
It is in inverted U-shaped socket that one is set in the fixture of thing, is respectively formed with two madial walls of the socket described in being inserted into
Raised line in slot is installed.
Described two install the center line of slot in the same plane, and it is in parastate that two are installed slot.
Between 3-8mm, depth is between 0.5-1.5mm for the groove width for installing slot.
Diameter of the width of the socket more than the infrared anti-reflection lens.
The width of the raised line is identical with the groove width of the installation slot, and the installation slot capping processing is missed during processing
Difference, the mismachining tolerance that raised line is removed the limit.
By extending the external infrared anti-reflection lens outer surface setting slot of shell in the present invention, can use cooperatively
Nipper, it is ensured that spectrum analysis is more accurate.
