ABSTRACT:
A sample cell of the multiple reflection type is used for analyzing a sample in the same cell. In the sample cell, incident light is reflected a plurality of times. The sample cell includes a mirror plate including a light incident window for introducing the incident light into the sample cell, a first concave mirror, and a light exit window for outputting the incident light form the sample cell. A side plate including a second concave mirror reflects the incident light to the first concave mirror and a third concave mirror for reflecting the incident light reflected by the first and second concave mirrors to the light exit window. The cell also includes a frame for fixing the mirror plate and the side plate so that the distances between the first concave mirror and the second and third concave mirrors are fixed at a distance equal to the radius of curvature of the three concave mirrors.
