<p>In this terahertz-wave spectrometer (1), a dispersing prism (31) is provided with a prism part (52) capable of sliding with respect to a main part (51). A plurality of placement regions (K) on which substances to be measured (34) are laid out, in the direction in which the prism part (52) slides, on a placement surface (31c) (namely, the top surface) of the prism part (52). Thus, when optical constants of one substance (34) are finished being measured, the prism part (52) can be slid in order to move the next substance to be measured (34) into the path of terahertz waves (T), making it easy to measure a plurality of substances (34) without cleaning the placement surface (31c) in between.</p> |
