LOW-TEMPERATURE DIFFUSE REFLECTION MEASURING APPARATUS, SAMPLE HOLDER USED FOR THE SAME, AND LOW-TEMPERATURE DIFFUSE REFLECTION SPECTRUM MEASURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a low-temperature diffuse reflection spectrum measuring apparatus for powder samples capable of preventing samples from freezing at low temperatures and easily measuring the diffuse reflection spectra of the powder samples at controlled temperatures.;SOLUTION: In the low-temperature diffuse reflection spectrum measuring apparatus 10 for powder samples, a cryostat 12; a powder sample holder 13 for measuring temperature changes and spectra connected to a cryostat heat conducting part 21 via a heat conducing plate 22 and a heat conductor 18 for holding a powder sample in the vicinity of an inner side of a cryostat optical window 28; and a diffuse reflection photo-detecting means provided with both an integrating sphere 14 and a detector 16 are combined.;COPYRIGHT: (C)2005,JPO&NCIPI
