Description
Technical field
The utility model is related to a kind of new detection means, and in particular to spectrum analysis field.
Background technology
Every kind of atom has the characteristic spectral line of oneself, therefore can differentiate material according to spectrum and determine its chemical group
Into this method is called spectrum analysis.When doing spectrum analysis, it is possible to use emission spectrum, it is also possible to utilize absorption spectrum.It is all
Liquid, the spectral absorption of gas all follow langbobier law, i.e.,A represents absorbance, I in formula0Table
Show that source emissioning light is strong, I1Transmitted light intensity is represented, K represents molar absorption coefficient, and C represents the concentration of extinction material, and L represents absorption
Light path.
The Single wavelength detection method that presently, there are have the advantages that simply, efficiently, be easy to operation.But easily by external condition
Interference, accuracy are low.Therefore a kind of detection means for being difficult to be disturbed by external condition, the degree of accuracy is high, sensitivity is high is developed outstanding
For important.
The content of the invention
In order to solve above-mentioned the deficiencies in the prior art, the purpose of this utility model is to design a kind of adjustable pair of optical path difference
Divide detection means.The device can not only improve material detection sensitivity and accuracy, in structure also compact volume and convenience, reduce technology into
This, operates also more convenient.
The utility model solves the technical scheme that its technical problem used：
Adjustable pair of light path Differential Detection device is made up of base, sliding block, optical fiber collimator.Described base is L-shaped, side
Face is provided with two optical fiber collimator interfaces；Described sliding block is arranged on described base, is divided into the first sliding block and the second sliding block,
And it is provided with optical fiber collimator interface；Described optical fiber collimator has four, is separately mounted to four opened optical fiber collimators
On interface；Characterized in that, being provided with two grooves on described base, described slider bottom is provided with fastening bolt mouthful, relies on
Be fixed on sliding block on base by groove and fastening bolt.
Described base side is carved with graduation mark, and range is 200mm.
Optical fiber collimator interface on described base and described sliding block is helicitic texture.
Described two optical fiber collimator interfaces are opened on base, and two other interface is opened on two sliding blocks, sliding
Block can be moved freely, light path and optical path difference when it can change detection, and slider bottom has a bolt hole, for sliding block
Fixation and base between.
The beneficial effects of the utility model are：
1. two grooves are provided with design base, two slider bottoms are embedded in groove, can be sliding on base by sliding block
Move to change light path, reduce influence of the extraneous factor to measurement result, substantially increase sensitivity and the accuracy of detection.
2. design slider bottom has fastening bolt mouthful, for the fixation between sliding block and base, it is to avoid because of sliding block during test
Movement causes the inaccurate influence of test result.
3. design base side is carved with graduation mark, can directly read out light path value, is easy to follow-up calculating.
4. the optical fiber collimator interface on design base and sliding block is helicitic texture, in preventing test process, because of extraneous bar
Part causes optical fiber collimator shift in position, brings error, meanwhile, device can be completed by spin fiber collimater and changed, behaviour
Make simple and convenient.
The device is provided with four optical fiber collimator interfaces, and detachable optical fiber collimator is arranged in four interfaces.Two of which
It is immovable that interface is affixed to base, and two other interface is that on two sliding blocks, and the two sliding blocks can be left on base
Right slip, so as to change light path.There is fastening bolt on sliding block, being tightened after light path is determined just can fix.Base side
Scale is carved with, light path value can be directly read out, be easy to follow-up calculating.
The adjustable pair of light path Differential Detection device improves the shortcoming of traditional monochromatic light journey method and double light path methods, light
Source is aging and system noise influence is small, can quickly determine system sensitive wave-length coverage, be easy to systematic lectotype (spectrometer grating,
The type selecting of CCD and optical fiber), drastically increase sensitivity and the accuracy of spectral detection.
