Abstract: In a textile color analyzer, a sample of textile is supported on the pad of an elevator mechanism that holds the sample against an instrument head. The head has an opaque housing provided with a chamber having an opening therein. A glass plate is mounted in the head and covers the opening and presses against the textile sample to provide a stable reference plane. The head includes an illuminating fiber optic bundle that directs light substantially perpendicular to the textile sample. A plurality of additional fiber optic bundles are mounted to receive diffuse light reflected from the sample. The elevator includes a pad of translucent polyethelene material that backs up the textile sample and takes on the color of the sample so that there are no adverse effects due to light showing through the sample and reflecting from the plate.
