Description
Technical field
The utility model belongs to thin-film material analytical equipment field, and in particular to one kind is infrared based on small size thin-film material
The fixture of spectrum test.
Background technology
In modern thin-film material constituent analysis, infrared spectrum is in quantitative detection film functional group ingredient, thus it is speculated that forming thin film
It has a wide range of applications in the process.The characteristics of infra-red sepectrometry is:Quickly, sample size is few (several micrograms-several milligrams), and characteristic is strong
(various substances have its specific infrared spectrogram) can analyze the sample of various states (gas, liquid, solid) and not destroy sample.
The principle of existing Fourier infrared spectrograph is:The light that light source is sent out is divided into two beams by beam splitter (similar semi-transparent semi-reflecting lens), and one
Beam reaches index glass through transmission, and another beam reaches horizontal glass through reflection.Two-beam returns beam splitter through horizontal glass and index glass reflection respectively,
Index glass is for linear motion with a constant speed, thus the two-beam after beam splitter beam splitting forms optical path difference, generates interference.Interference
Light, by sample cell, reaches detector by the interference light containing sample message after sample, then passes through after beam splitter congregation
Fourier transform pairs signal is handled, and finally obtains transmitance or absorbance with wave number or the infrared absorpting light spectra of wavelength.
Film in reflection absorption spectrum method energy high sensitivity measuring metallic substrates, when polarizing light irradiation is in metallic substrates
On, when being reflected in metal surface, its phase can change.In the case of orthogonal polarized light, mutually become about 180 °, with
Incidence angle is unrelated, therefore the vector of reflected light offsets each other, and standing wave amplitude is almost nil, can't detect the absorption of sample.In water
In the case of flat polarised light, continuous change of phase changes to 90 ° from 0 °, and standing wave amplitude equally changes with incidence angle.Work as selection
Standing wave amplitude increase during big incidence angle, the effect enhancing of light beam and sample, so as to generate high detection sensitivity.Metallic reflection
Rate is higher, therefore this method can detect the film on metal with sensitivity.
In practical operation, (the light path principle figure of its sample test such as Fig. 1 institutes by taking Shimadzu IR series RAS8000 (A) as an example
Show, M in figure1~M6For speculum), as can be seen from Figure 1, since light source is under, sample surface should be placed downward.Actually equipment
There is sample cell with holes for placing sample, sample cell there are tri- kinds of specifications of Ф 8/15/25mm, in hollow circular hole.Preferable sample is
Film in metal substrate, and substrate dimension has to be larger than Ф 8mm, therefore too small sample will fall off, and can not test.This is to a variety of
The sample test prepared on different type substrate brings certain difficulty.
Utility model content

Fixture be inverted on the specimen holder of Shimadzu Fourier infrared spectrograph, sample to be tested is made to be placed in specimen holder trepanning middle position,
It can start to test.
Further, the size of the small size thin-film material is 2mm*2mm~20mm*20mm.
The principle of the utility model is:By sample being sticked to below the fixture with metal substrate so that small size sample
Product will not directly be fallen down from specimen holder tapping, and infrared light directly acts on sample surfaces, and fixture has metal substrate in addition, from
And there is larger reflectivity, it is ensured that sample signal intensity is sufficiently high.
The utility model has the following advantages that and advantageous effect:
The utility model solves small size film sample and is using Shimadzu Fourier red with a kind of simple sample clamp
The problem of sample encountered in external spectrum test is fallen, signal is weak, test size range is extended to not less than area of section
The sample of 2mm*2mm, and enhance the test intensity of sample by plating layer of metal film on a glass substrate, there is very strong reality
The property used.
