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 polyethylene 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.

Abstract: A spectrophotometer includes a wide band radiant energy source and a detector for providing an output signal proportional to the intensity of the radiant energy received thereby. A light pipe system is divided into a reference path and a sample path. Such system coacts with a rotary assembly having a variable monochromatic filter located diametrically opposite to an opening through which radiant energy can freely pass. The remaining portions of the rotary assembly are opaque so that as the assembly turns, the sample and reference paths are serially energized by monochromatic energy and then by polychromatic energy. The sample path includes a sample illumination and collection system for illuminating a test sample and collecting the light reflected therefrom. The resultant output of the detector can be analyzed to determine the amount of fluorescence.
