Description
技术领域Technical Field
本实用新型涉及拉曼光谱检测技术领域，具体涉及一种拉曼光谱检测装置。The utility model relates to the technical field of Raman spectrum detection, in particular to a Raman spectrum detection device.
背景技术Background technique
拉曼光谱检测技术是一种利用激光作为激发光源，通过检测样品所产生的拉曼光谱，进行物质成分分析的检测方法。由于样品所产生的拉曼光谱非常微弱，大约只有激光激发出光强的10-10～10-6，因此如何使激光聚焦点精确落在被测样品上，同时又能精确落在拉曼光谱收集透镜的焦点上，从而提高拉曼光强的收集效率，成为了激光拉曼光谱仪中需要解决的一个重要问题。Raman spectroscopy detection technology is a detection method that uses laser as an excitation light source to detect the Raman spectrum generated by the sample to analyze the composition of the material. Since the Raman spectrum generated by the sample is very weak, only about 10-10 to 10-6 of the light intensity excited by the laser, how to make the laser focus point accurately fall on the sample to be tested and at the same time accurately fall on the focus of the Raman spectrum collection lens, thereby improving the collection efficiency of the Raman light intensity, has become an important problem that needs to be solved in laser Raman spectrometers.
传统的样品快速对中的方式，通常是将搭载有样品的承载台在探头下移动，通过改变样品的位置，寻找到一个较佳的检测点，使检测者可以检测到样品最大的拉曼光信号。然而这种方式操作十分不便，需要反复调节增加检测次数，并且移动精度较低，导致检测效率较低。The traditional method of rapid sample alignment is usually to move the sample-carrying platform under the probe, and by changing the position of the sample, find a better detection point so that the detector can detect the maximum Raman light signal of the sample. However, this method is very inconvenient to operate, and requires repeated adjustments to increase the number of detections. In addition, the movement accuracy is low, resulting in low detection efficiency.
