Abstract

The invention discloses a small-pore-diameter long-distance optical compatible vacuum sample cavity. The vacuum sample cavity comprises a low-temperature sample rod, a multi-channel connecting device, an ultrahigh vacuum angle adjustable device, an ultrahigh vacuum XYZ three-dimensional displacement platform, an upper cavity body, an optical window and a window protecting cavity which are sequentially arranged from top to bottom. The low-temperature sample rod is in vacuum sealing connection with the multi-channel connecting device which is in vacuum sealing connection with the ultrahigh vacuum angle adjustable device. The ultrahigh vacuum angle adjustable device is in vacuum sealing connection with the ultrahigh vacuum XYZ three-dimensional displacement platform which is in vacuum sealing connection with the upper cavity body. The upper cavity body is in vacuum sealing connection with the optical window which is connected with the window protecting cavity. The vacuum sample cavity is suitable for small-pore-diameter long-distance conditions, generates high-vacuum environment, and can be used for optical properties of optical detection materials.

Description

technical field [0001] The invention relates to a small-aperture long-distance optically compatible vacuum sample chamber, which is a system for measuring optical properties of materials in a high-vacuum and extremely low-temperature environment with small space aperture and long distance. Background technique [0002] In modern physics experiments, it is often necessary to use optical means to measure the properties of materials in a high-vacuum and low-temperature environment, such as the measurement of ultrafast magneto-optical properties of related electronic materials. Moreover, in modern physical experiments, it is often encountered that the experimental operation space has a small aperture and a long distance. For the smooth progress of the experiment, at least three points must be considered: the first point is to allow light to propagate in a small and long space, The second point is that the light can reach the sample, and the third point is to ensure the high vacu...
