ABSORPTION SPECTROMETER

The invention discloses an absorption spectrometer. In order to reduce a variation in the light amount of light detected in every reference measurement cycle in an absorption spectrometer (1), it is adapted to tilt at least one surface selected from among incident surfaces and emitting surfaces of all translucent members constituting a reference cell with respect to the light axis of light traveling along a light path. 本发明提供种吸收光谱仪(1)，为了减小每次参比测定时检测到的光的光量的变动，从构成参比池的全部透光部件的入射面和射出面中选择的至少个面相对于在光路上行进的光的光轴倾斜。
