Description
Technical field
The utility model relates to laser Raman spectrometer, especially relates to laser Raman spectrometer solid and fluid sample focusing micromotion platform device.
Background technology
Laser Raman spectrometer is applied to and detects various Matter Composition, is a kind of Dynamic Non-Destruction Measurement, and have untouchable, the non-destructive of test sample, required amount of samples is few, and detection time is short, and sample is without the need to features such as preparations in advance.Therefore the fields such as medicine, archaeology of cultural relic, Gemstone Identification, food security and criminal investigation are widely used in.But the Raman spectrum produced due to institute's test sample product is very faint, approximately only has 10 of laser excitation main line light Strong
-10~ 10
-6, therefore, how to make Laser Focusing point accurately drop on sample, as much as possible improve the collection efficiency of Raman light intensity, become in laser Raman spectrometer the major issue needing to solve.
At present, large-scale precision laser Raman spectrometer on market be all furnished with optics or videomicroscopy platform, by regulating the Precision trimming mechanism of X-Y-Z three-dimensional, solid sample in detection platform or fluid sample can be positioned at by fine adjustment, sample is on best tram fast.So both can improve the collection efficiency of Raman light intensity, save detection time again, improve the detection efficiency of sample.But because microscope stage manufacturing cost is higher, volume is comparatively large, is only suitable for using in large-scale instrument, is unsuitable for being used in miniature instrument.
Medium-sized laser Raman spectrometer, because small volume, cost are low, generally be not equipped with other servicing units, in measuring process, only armrest moves front end solid sample or fluid sample being placed on laser probe, by the position of mobile example, search out a Best Point, make tester the Raman light signal that sample is maximum can be detected.Although this method is simple but operate very inconvenient, need usual test experience accumulation, each measurement needs just can find a suitable position by the test of repeatedly repetitiousness, even professional is also difficult to find an optimum position fast, measures detection efficiency very low.
Summary of the invention
