Abstract
An apparatus for making automated measurements of an optical property of a sample includes a first stage which is movable along a predetermined line, a second stage for holding the sample, and a third stage which is movable along a predetermined line, correspondingly to the motion of the first stage. A light source is mounted on the first stage, and a light detector is mounted on the third stage. The second stage rotates the sample to a selected rotary position. The apparatus also includes a controller for coordinating movement of the first, second, and third stages such that the light source, the sample, and the light detector are optically aligned.
