Upper, circle ring disk 4 is put into the vertical rod of the upper band of pole inserted base 1 for inlaying in support 3, inlaying the upper band of support 3 and by screw 2
Angle index 6 is carried on fixed, circle ring disk 4, the structure with mark 7 on support 3 is inlayed, accommodated, accurately done polarised light
Experiment is provided to be supported.It can be seen that, the invention enables optical multichannel analysis experiment instrument of the prior art increased experimental project and
Experiment content, a tractor serves several purposes, but cost is relative to improve minimum（The optical multichannel analysis experiment instrument of prior art is often enclosed within 1.7
Ten thousand yuan or so, and increased cost of the invention is also with regard to more than 100 yuan）, significantly improve instrument utilization benefit.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Fig. 2 is the structural representation of analyzer of the present invention 13.
Fig. 3 is the circuit diagram of LED light source in the present invention.
Specific embodiment
In Fig. 1, monochromator 9 is connected with each other by ccd data line with electronic box 10, electronic box 10 by motor drives line Y with
Monochromator 9 is connected with each other, and electronic box 10 is also connected with each other by USB line U with computer 14, is also carried between light source 11 and slit 15
The polarizer 12 and analyzer 13.
In fig. 2, analyzer 13 is by base 1, screw 2, inlays support 3, circle ring disk 4, polarizer 5, angle index 6, mark
What note 7 was constituted.Wherein polarizer 5 is arranged on circle ring disk 4, and circle ring disk 4 is put into be inlayed in support 3, inlays the branch of the upper band of support 3
Fixed in the vertical rod of the upper band of bar inserted base 1 and by screw 2, angle index 6 is carried on circle ring disk 4, inlayed on support 3 with mark
Note 7.The structure of the polarizer 12 i.e. can be completely the same with analyzer 13, can also simplify its structure, such as remove angle index 6 and mark
Note 7, or even simpler framework is also reduced to support 3 is inlayed, directly polarizer 5 is fixed on framework, while annulus
Disk 4 is also omitted.
The top half for inlaying support 3 can be bent or be stamped to form with sheet metal, it is also possible to Mold Making.Inlay support 3
The latter half be a pole for cylinder, the top half and the latter half for inlaying support 3 are welded to each other or other modes
Interfix.The recess width of the top half of support 3 is inlayed, is advisable with the thickness for just accommodating circle ring disk 4, so that circle ring disk
4 be able to can only rotate but not axial activity is defined in groove.The parts transversely width of support 3 is inlayed just to accommodate annulus
Disk 4 and not left and right activity are defined.The top half height for inlaying support 3 is advisable with 2/3rds more than the diameter of circle ring disk 4,
Can be the removable structure of framework but upper side frame for inlaying support 3 and being made square Shape closed.Polarizer 5 and between circle ring disk 4
With screw the mode of fastening frame or bonding can be coordinated fixed with each other.One week of circle ring disk 4 or half cycle will manufacture survey
The angle index 6 of measuring angle, meanwhile, also manufacture mark 7 in the lower frame middle position for inlaying support 3, thus can accurately,
Easily read the angle that polarizer 5 is turned over（During experiment, with the corner of hand adjustment pitch circle the ring disk 4）.
Light source 11 in Fig. 1 can be mercury lamp, hydrogen lamp, it is also possible to LED（Light emitting diode）Light source.The circuit of LED light source
See Fig. 3.LED light source is formed by connecting by dc source 16, light emitting diode 17, ammeter 18, voltmeter 19.Wherein luminous two
Output end again with voltmeter 19 and dc source 16 is in parallel after pole pipe 17 is connected with ammeter 18, with electricity on dc source 16
Stream adjusting knob 20.Ammeter 18 and voltmeter 19 can use the Miniature digital electric current and voltmeter head of prior art, its direct current to supply
Power supply is retrieved from dc source 16 again plus three terminal voltage regulator circuit is formed, and this can simplify circuit structure and cost.Electric current is adjusted
Knob 20 is really the knob on a potentiometer, and the potentiometer can change the output voltage of dc source 16.Dc source 16
Can be with 220V electric mains of the prior art by after transformer pressure-reducing, rectification, filtering, then by adjustable mu balanced circuit structure
Into.Dc source 16, light emitting diode 17, ammeter 18, voltmeter 19, current adjusting knob 20 can be installed to same
In casing, but the setting height(from bottom) of light emitting diode 17 also can will individually take out light emitting diode 17 with slit 15 with height,
It is installed on a height-adjustable lamp bracket（This refers to the structure of base 1 in Fig. 2）, it passes through wire and dc source again
16 electrical connections.
The present invention when in use, can both do experiment content of the prior art, again can be polarised light experiment, LED
The experiments such as photoluminescence Study experiment, the test of LED C-V characteristics, significantly extend the experiment content of the instrument.Do polarised light reality
When testing, the deflection angle for first adjusting analyzer 13 is identical with the polarizer 12, now the spectral line highest on computer screen（Or energy
Numerical value is maximum）, then by changing some different deflection angles of analyzer 13 so that the polarised light through the polarizer 12 passes through inspection
A different set of height of spectral line corresponding data is obtained after inclined device 13, the experiment of checking Malus' law or other experiment contents are done.Again
Light source 11 is changed into LED light source, as soon as the regulation group curtage data of current adjusting knob 20, obtain one group on computer screen
Correspondence height of spectral line（Or energy values）Data, it is possible to study relation, spectrum and the electricity of the luminous light intensity of LED and electric current
The experiment contents such as the relation of stream.The present invention can also carry out other experiment content extensions, no longer describe.
It can be seen that, the present invention significantly extends the experiment content of optical multichannel analysis experiment instrument, experiment it is comprehensive stronger, both
Be conducive to the culture of student ability, the utilization rate of instrument is improve again.But cost of the present invention is relative to improve minimum（Prior art
Optical multichannel analysis experiment instrument be often enclosed within 1.7 ten thousand yuan or so, and increased cost of the invention is also with regard to more than 100 yuan）, significantly carry
The utilization benefit of instrument high.
