Problems solved by technology

[0003] The existing micro-spectroscopy system cannot realize the multi-functional in-situ spectral measurement under the diamond press. The main problems are: the reflection of light by multiple interfaces in the diamond press makes the signal-to-noise ratio of the measurement spectrum poor, and it is difficult to achieve accurate measurement ;The commonly used transmission objective lens cannot realize wide-spectrum data acquisition; the working distance of the objective lens is not enough, and the minimum working distance required by the diamond press is 16mm; and it cannot take into account the fluorescence spectrum, absorption spectrum, reflection spectrum, and optical path design for fluorescence imaging and spectrum acquisition

The multifunctional wide-range spectral measurement device solves the technical problem that the fluorescence spectrum, the fluorescence imaging, the absorption spectrum and the reflection spectrum of a sample in the diamond press under high pressure are difficult to measure at the same time by means of an existing testing device, and realizes integrated in-situ measurement of the sample in the diamond press.

Description

technical field [0001] The invention relates to a spectrum measuring device, in particular to a multifunctional wide-range spectrum measuring device for a diamond press. Background technique [0002] High pressure is a controllable extreme condition widely used in the research of material science. When a substance is compressed under high pressure, its physical and chemical properties will change, and it can also form or transform into new structures and new materials that have not yet been recognized. High-pressure technology and its in-situ characterization provide new means and possibilities for natural science research. A diamond press, also called a diamond counter-anvil, is the most commonly used and effective device that can provide a high-pressure environment and realize in-situ characterization. The sample is sealed in a sealed cavity formed by two diamonds and a gasket. [0003] The existing micro-spectroscopy system cannot realize the multi-functional in-situ sp...
