The invention discloses a device for testing the focusing performance of an X-ray compound reflective lens. The device comprises a base guide rail, an X-ray light pipe located on the base guide rail, a laser, a metal wire and an X-ray detecting device. An adjusting table is located on one side of the base guide rail, and the X-ray light pipe and the laser can be horizontally and movably installed on the adjusting table. The X-ray compound reflective lens to be detected is located in the middle of the base guide rail, and the X-ray detecting device is located on the other side of the base guide rail. An adjusting support can be longitudinally and movably arranged on the base guide rail between the X-ray compound reflective lens to be detected and the X-ray detecting device. A horizontal sliding block can be horizontally and movably arranged on the adjusting support, the metal wire used for cutting detected light beams which are focused by the X-ray compound reflective lens is installed on the horizontal sliding block, and the size of the metal wire needs to meet the requirement for micron dimension. The device for testing the focusing performance of the X-ray compound reflective lens is capable of simplifying the structure and greatly reducing cost, and good in practicality.
Description
technical field [0001] The invention relates to the field of X-ray detection and imaging, in particular to a device capable of measuring the focusing performance of an X-ray combined refraction lens. Background technique [0002] The X-ray combined refraction lens is a new type of X-ray focusing device based on the refraction effect. Its theoretical focus spot size can reach the nanometer level. The actual test focus spot size is usually several microns, and it has small size, simple manufacturing process, The advantages of good robustness and batch processing are suitable for X-ray detection and imaging systems with high detection resolution; secondly, the X-ray combined refraction lens covers a very wide range of photon energies, so X-ray detection and imaging systems based on it are suitable for In a variety of applications; finally, because it is based on the refraction effect, it does not need to bend the optical path when focusing the X-ray beam, so the formed detectio...
