Design of microscopic imaging sample rod for water-cooled magnets

Existing micro-imaging systems are primarily designed for specific types of magnets and are not compatible with watercooled magnets, posing significant limitations in their use. In light of this, the article proposes a solution: a micro-imaging sample rod suitable for water-cooled magnets, designed for easy installation and removal. The microscopic imaging sample rod consists of an upper optical path box and a lower rod body. The optical path is integrated within the optical path box, divided into five layers, each securely fixed inside the box. The upper and lower parts of the optical path box can connect freely. The optical components inside the optical path box are installed very compactly, enabling miniaturization of the optical path box. Simulation and modeling of the sample rod have yielded excellent results.
