X fluorescence spectrometer with protective net

The utility model relates to the technical field of optical measurement, and particularly discloses an X-ray fluorescence spectrophotometer with a protective net, which comprises a cabinet body, a test board is arranged at the top of the cabinet body, a first test window is arranged on the test board, a protective net assembly is arranged on the first test window, and the protective net assembly comprises the protective net and a peripheral structure. The main component in the material of the protective net is carbon. The carbon net basically has no blocking effect on X-rays and X-ray fluorescence, so that the final test result is basically not influenced by using the carbon net as the protective net. The elements below the test window are protected on the premise of not influencing the detection result, and the problem that the elements below the test window of the existing X fluorescence spectrophotometer are easy to damage due to misoperation in use is solved. 本实用新型涉及光学测量技术领域，具体公开了一种带有防护网的X荧光光谱仪，包括柜体，柜体的顶部
