Paper Abstract

For measuring the UV-VIS spectra of single hydrocarbon inclusions, a new micro-spectroscopy system based on inverted microscope and reflective objective was established in this paper. This system includes a reflective objective, a micro-lens, a fiber cable, a 3D adaptor, a spectrometer and a common inverted microscope. The 3D adaptor was perfectly connected with the microscope and no need any rebuilding to the microscope. The reflective objective can be easily con-focused with the objective of the microscope. By the fiber cable, the micro-lens and the reflective objective, the external monochromatic light from the spectrometer was used to excite the inclusions. Using this system, we measured VIS spectra of the inclusions excited by the internal mercury lamp of the microscope. We also measured the spectra of the single inclusions excited by external monochromatic light source. In this case, the influence of the fluorescence of the grain around the inclusion was subtracted from the total spectrum. At the same time, the images of the inclusions were recorded by a CCD camera. Because this system has a low cost, stable and a high sensitive, it is promising to measure the fluorescence of micro-size samples.
