The annular micropore optical lens (MPOS) is a special array type micropore optical element, and adopts the radial micropore array manufacturing technology to manufacture a fan-shaped micropore array optical element, and the fan-shaped micropore array optical element is formed into a spherical sector structure through hot bending. The annular microporous optical lens (MPOS) has important application in the fields of high-energy physics and celestial physics, and is a key optical device for forming a novel Wolter-I telescope.

At present, the research bases for the preparation process and the performance test of the annular microporous optical lens (MPOS) at home and abroad are relatively few, and a technology for comprehensively evaluating the optical performance of the annular microporous optical lens (MPOS) is not found. The applicant is interested in studying the materials and processes for the preparation of annular microporous optical lenses (MPOS) and in the development of optical and electronic systems for the overall evaluation of the optical properties of MPOS lenses. In order to realize the optical test of the MPOS lens, a test device is required to be designed to clamp the MPOS lens, on one hand, the device cannot influence the surface type and the optical test of the MPOS, on the other hand, in order to carry out comprehensive quality performance evaluation on the MPOS, fine adjustment of the spatial attitude is required to be added on the basis of clamping, and therefore the requirement on the test device is extremely high. In addition to the installation and adjustment requirements, considering that the assembling of MPOS components requires the assembling of different MPOS lenses with ultra-high precision, it is a great challenge to design the optical assembling device.

The spatial orientation of the MPOS lens directly determines the optical effect of the lens, and in order to further adjust the spatial orientation of the lens according to the optical result of the lens, research on an MPOS lens optical assembly apparatus is required. At present, the research of domestic MPOS lens optical assembling devices starts late, only one simple assembly device exists at present, as shown in figures 1a-1b, the device has the advantages that 6 MPOS lenses can be clamped simultaneously to form an assembling assembly, and the device has the disadvantages that once the lenses are clamped, the lenses cannot be disassembled and adjusted, and the overall evaluation of the assembling effect cannot be realized on the whole and single lenses.
