Abstract
A device for holding and positioning a sample (22) during spectral analysis, having an optical cell (41) comprised of a base member (42), a glass cell (44), and being filled with oil (46) having substantially the same index of refraction as the glass cell (44). The device further includes a rotary stage device (48) attached to the optical cell (41) and a sample holder (50) attached to the rotary stage device (48) such that a sample (22) may be rotated over a range of angles relative to a projected beam (32) to provide a spectral analysis of the sample (22) over the range of angles.
