PURPOSE:To make the number of waves in a direction of a prism bottom coincide with the number of waves of surface electromagnetic waves to obtain a sufficient S/N ratio by uniformly pressing a film against a reflecting surface of a highly refractive prism and preventing divergence of incident light and outgoing light to the prism while an incident surface and an outgoing surface are made flat. CONSTITUTION:An object of analysis with this spectrometer is popolarization. In performing analysis, a crimp screw receiving jig 12, a crimp screw 13 and a crimp plate 14 are used to press a film 51 on which a thin film 53 being a specimen is deposited against a reflecting surface of a highly refractive prism 16. The film 51 is made of plastic such as PET and aluminum 52 has been deposited on it. The prism 16 is equipped with a flat reflecting surface while a reflecting mirror 17 and an angle adjusting mechanism 20 are used to adjust incident and outgoing angles with respect to a crystal. By thus constituting the spectrometer and turning the screw 13, the crimp plate 14 is lowered together with a cushion 41, and the PET film 51, the aluminum deposited film 52 and a specimen 53 are integrally pressed against the reflecting surface of the prism 16 so as to reduce a loss in infrared rays. |
