    Abstract
    The elastic-port immersion cell (10) is an optical oil immersion vessel which has a flexible latex (or other) sheath (24) protruding from its sidewall. The sheath is affixed to an opening in the wall of the vessel using a collar, O-ring (26) or other connecting means. The base of the vessel is an optical glass window. A sample (20) mounted on to the end of spindle (14) is placed into the cell. The end of the spindle (14), without the sample, is inserted into the sheath and the latex together with the spindle is attached to a goniometer head of a spindle stage such that the spindle is horizontal. Immersion oil (22) that has a refractive index similar to the sample is added to the cell until the sample is totally submerged. Minute features within the sample (20) may then be observed under the microscope as the sample is rotated 360 degrees about a vertical or horizontal axis. The latex sheath prevents the oil from escaping from the cell and also provides the flexibility required to orient and rotate a sample.
