A deep cryogenic three-dimensional adjustable sample holder

Abstract

The invention discloses a profound hypothermia three-dimensional adjustable sample holder. The profound hypothermia three-dimensional adjustable sample holder comprises a constant-temperature sample holder; a horizontal adjusting support plate connected to the constant-temperature sample holder through horizontal adjusting nylon screws so as to adjust the horizontal position of a fixed sample; and an adjustable sample support connected to the adjustable sample support through inclination angle adjusting nylon screws so as to adjust the inclination angle with the fixed sample. The profound hypothermia three-dimensional adjustable sample holder achieves three-dimensional light path adjustment at the sample end and improves the measuring accuracy and reliability.

Description

technical field [0001] The invention relates to the technical field of optical measurement, in particular to a cryogenic three-dimensional adjustable sample holder. Background technique [0002] In today's scientific research, cryogenics are a very common method, especially in optical measurements, the use of cryogenics is of great help to the study of physical phenomena such as lattice vibrations, electronic energy bands, and structural phase transitions. The means of deep cryogenics in experiments is usually achieved using deep cryostats, and these deep cryostats usually have a temperature range of 3-300K. Oxford Company of the United Kingdom and Janis Company of the United States are currently two companies mainly engaged in the research and production of cryogenic systems in the world. Usually cryostat experiments require a cryostat to be used in conjunction with a spectrometer. Since the optical path of the spectrometer is fixed, the position of the cryostat is require...

Problems solved by technology

However, the sample holders provided by these two companies are all fixed sample holders, which cannot be adjusted. Due to the needs of optical measurement, it is very necessary to adjust at the sample end. The current method used is to move the entire deep cryostat. To achieve the purpose of adjustment, this adjustment has two major disadvantages: 1. The deep cryostat is often cumbersome and difficult to adjust

2. Due to the fixed way of the deep cryostat, the adjustment dimension of the whole deep cryostat is limited

Due to these two disadvantages, the existing adjustment methods are often difficult to adjust to the best position, which is very difficult for the light alignment of spectral measurement

It brings a lot of inconvenience to the measurement, and also affects the accuracy and reliability of the measurement
