Description
Technical field
The utility model is related to light spectrum detecting apparatus field, specially a kind of sample fixed support for spectral detection.
Background technology
With the progress of Terahertz Technology, the application of Terahertz Technology is also increasingly extensive.Current Terahertz Technology is typical
It is terahertz time-domain spectroscopy system (THz-TDS) using realizing, it is necessary to light path passes through sample when using the system（Thoroughly
Penetrate mode）, or light path is through sample reflection（Reflection mode）, because the light path of terahertz time-domain spectroscopy system uses opening side
Formula or semi-open mode (light path is closed in a shell), the device for not having special placement sample, to the measurement of sample
Make troubles.For terahertz time-domain spectroscopy system, sample can be solid-state or liquid, and solid sample generally requires compacting
Into the thin slice of diameter 1cm, liquid sample need to try out cuvette or liquid cell (salt window) is contained.
Therefore, being related to one kind makes sample fix in the optical path, and height adjustable can make light path just by test sample
Center；And the cuvette of different in width and the sample fixed support of liquid cell can be fixed, being one is worth research
Problem.
The content of the invention
In order to overcome above-mentioned deficiency of the prior art, the utility model provide it is a kind of can be by the colorimetric of different in width
Ware or liquid cell are fixed in the optical path, and support height is adjustable, and sample center can be made just by light path, and draw-in groove width is adjustable,
Whole support can enable the sample fixed support for spectral detection of the safe and stable test of sample.
What the purpose of this utility model was realized in：
A kind of sample fixed support for spectral detection, including base 8, are arranged on the lifting platform 7 on base 8, described
Lifting platform 7 on be provided with translation stage 6；
Base fixing bolt is provided with described base 8, for being fixed with optical table；
The described rectangular bending of lifting platform 7, is provided with the fixing hole of longitudinal direction ellipse on the stage body of lower end, set in fixing hole
It is equipped with the lifting platform fixing bolt being fixed with base 8；Upper end is provided with longitudinal block, longitudinal block be located at lifting platform water
Put down to broad-adjustable draw-in groove 5 is provided between the translation stage 6 on stage body, draw-in groove 5 is interior to be provided with cuvette or liquid cell 4；
Being provided with described translation stage 6 carries out the translation stage fixing bolt of position fixation with lifting platform 7.
Positive beneficial effect：The utility model good stability, it is adaptable to the fixation of various shuttles.The stent applications in
Terahertz time-domain spectroscopy instrument, can avoid touching sample due to adjusting, so as to cause sample to be translated into, cause sample reveal or
Broken problem.Further, since support stability is good, can avoid due to vibration, the air flow on optical system for testing is to sample
The vibration of generation, so as to reduce test noise.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
It is in figure：Receiver module 1, the first Terahertz permeable membrane 2, the first optical lens 3, cuvette or liquid cell 4, draw-in groove 5,

Drop platform 7, translation stage 6 is provided with described lifting platform 7；
Base fixing bolt is provided with described base 8, for being fixed with optical table；
The described rectangular bending of lifting platform 7, is provided with the fixing hole of longitudinal direction ellipse on the stage body of lower end, set in fixing hole
It is equipped with the lifting platform fixing bolt being fixed with base 8；Upper end is provided with longitudinal block, longitudinal block be located at lifting platform water
Put down to broad-adjustable draw-in groove 5 is provided between the translation stage 6 on stage body, draw-in groove 5 is interior to be provided with cuvette or liquid cell 4；
Being provided with described translation stage 6 carries out the translation stage fixing bolt of position fixation with lifting platform 7.
When using, sample fixed support is arranged between transmitter module 11 and receiver module 1；Transmitter module 11 and reception
It is saturating that the top of module 1 is respectively arranged with the first Terahertz permeable membrane 2, the first optical lens 3 and the second optical lens 9, the second Terahertz
Film 10；Described the first Terahertz permeable membrane 2, the first optical lens 3 and the second optical lens 9, the second Terahertz permeable membrane 10 are distinguished
Positioned at the support bracket fastened both sides of sample；The sample fixed support is made up of three parts：Base, lifting platform and mobile station.Base band
There is base fixing bolt, can be fixed on optical table, lifting platform highest liftable 4cm, when suitable height is elevated to,
Screw down, with level altitude, according to by the thickness of fixed sample, draw-in groove width is adjusted by translation stage, draw-in groove width is most
Big reachable 2.8cm.After draw-in groove is adjusted to suitable width, screw down, to fix sample；Terahertz time-domain spectroscopy system has
Visible ray positioner, to ensure that sightless terahertz light can penetrate sample center.
The fixed support base 8 uses stainless steel, to increase base weight；Base 8 is provided with 4 lifting fixing bolts；
Support lifting platform part uses aluminium alloy, and the oval interior electrical path length in the longitudinal direction for adjusting height is 0-4cm；Support translation stage portion
Divide and use aluminium alloy, draw-in groove width range 0-2.8cm, depth 1cm.During machining, it is desirable to which draw-in groove occlusion is tight, and error does not surpass
Cross 0.05mm；Lifting platform fixing bolt 1, is installed on the plastic handle on lifting platform fixing bolt, diameter 1cm；Translation stage is consolidated
Determine knob 1, diameter 0.4cm.
The utility model good stability, it is adaptable to the fixation of various shuttles.The stent applications are in terahertz time-domain light
Spectrometer, can avoid touching sample due to adjusting, and so as to cause sample to be translated into, cause sample to reveal or broken problem.
Further, since support stability is good, can avoid due to vibrating, the vibration that the air flow on optical system for testing is produced to sample,
So as to reduce test noise.
Above case study on implementation is merely to illustrate preferred embodiment of the present utility model, but the utility model is not limited to
