Description

Technical Field

[0001] The utility model relates to the technical field of fluorescence spectrometers, in particular to a cavity structure of a fluorescence spectrometer. Background Art

[0002] A fluorescence spectrometer is a precision instrument for qualitative and quantitative analysis. It uses the fluorescence effect to excite matter through laser, causing its electrons to transition to an excited state, which then releases fluorescence when returning to the ground state. It can then measure and analyze the intensity and wavelength distribution of this fluorescence, measure and analyze the structure and composition of organic and inorganic substances, biological samples, etc., study the physical properties of materials, monitor environmental pollutants, and be used for disease diagnosis and treatment.

[0003] When using existing fluorescence spectrometers, most of them place the sample directly on the lens in the cavity. If the user accidentally touches the fluorescence spectrometer and causes it to shake, the sample in the cavity may move, resulting in errors during analysis and affecting the accuracy and efficiency of sample analysis. Therefore, a fluorescence spectrometer cavity structure is needed to meet people's needs. Utility Model Content
