[0027] Such as figure 1 Shown is a schematic structural view of the watertight pressure-resistant chamber that can be installed on the optical fiber probe of the ground object spectrometer according to the present invention. It can be seen from the figure that the watertight pressure-resistant chamber here includes a probe housing 6, an optical fiber 11, and an optical fiber sealing tube 9. Here, one end of the probe housing 6 is a transparent end, and the other end is provided with an extension tube 10; and the probe housing 6 is transparent. The end includes quartz glass 1, O-shaped sealing ring 2, quartz glass fixed sealing screw sleeve 3, and the "convex" shaped quartz glass 1 is fixed on the front end of the probe housing 6 through the hollow quartz glass fixed sealing screw sleeve 3, and the quartz glass An O-ring 2 is installed between 1 and the probe housing 6 to act as a water seal. Here, other materials such as plastics can also be used, as long as they have a certa...
