AI Technical Summary

Problems solved by technology

Although this type of optical element fixed installation adjustment assembly can accurately fix the relative position of the optical element, the disassembly and assembly are complicated. When it is necessary to replace a fixed plate assembly in the constructed system, it is necessary to disassemble most of the components in the same direction as the steel fixed rod. , which greatly increases the difficulty of reconstruction of the optical device, which is not conducive to the repeatability of the phenomenon in the optical system that requires extremely high accuracy of the relative position

It is also worth noting that due to the limitation of the cage system's four steel fixing rods and the through-hole structure of the fixing plate, the cage structure often cannot be directly equipped with a micron-level precision adjustment mechanism.

Coupled with the stress release problem and the deformation of the metal structure caused by temperature in the manufacture of all structures, this means that the optical path is not stable enough in most cases, and the cage structure cannot provide more precise adjustment of the optical path, which directly The reduction in the accuracy of optical systems in manufacturing and scientific research improves
