    Abstract:  分光測定装置1Aは、測定対象の試料Sから発せられる被測定光を観測するための積分球20と、試料Sが覆われるように試料Sの温度を調節するための媒体Rを保持すると共に、第2容器部50bが積分球20内に臨むように位置するデュワ50と、を備えている。試料Sが覆われるように媒体Rを保持するデュワ50を用いることにより、簡便に試料Sを所望の温度に調節することができる。第2容器部50bが積分球20内に臨むように位置することにより、積分球20の外部環境からの試料Sへの影響が抑制されつつ、試料Sの温度が媒体Rにより調節される。したがって、効率良く試料Sを所望の温度に調節することができる。

    Abstract: The invention concerns measurements in which light interacts with matter giving rise to changes in light intensity, and preferred embodiment spectrophotometer devices of the invention provide for ultrasensitive measurements through a reflection interaction with matter. The level of light source noise in these measurements can be reduced in accordance with the invention. Preferred embodiments of the invention use sealed housings (112, 600, 700) lacking an internal light source, and reflection based sample and reference cells. In some embodiments a substantially solid thermally conductive housing (600, 700) is used. Other features of preferred embodiments include particular reflection based sample and reference cells. A total internal reflection embodiment includes, for example, a prism (302, 322, 622a, 623 a) including an interaction surface, a detector, a lens that focuses a beam output from the prism onto the detector, and a closed interaction volume having an inlet and an outlet for delivering gas or liquid to the interaction surface. In a specular reflection embodiment, a reflective surface (402, 422) is used instead of a prism. In a diffuse reflection embodiment a matte surface (502, 522) is used instead of a prism and the matte surface produces scattering. Aspects of the invention include identification of noise-contributing components in spectrophotometry and the select set of preferred features in a given embodiment, and noise levels very near the shot noise limit may be realized with application of preferred embodiment devices.
