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.

Abstract: A spectrum analyzer is disclosed which is of the type that utilizes an electrically scannable array of optical detectors. The array is selectively illuminated, i.e. irradiated, by at least two portions of a spectral band image of radiation. One of the portions is associated with a first spectral range and the other portion is associated with a second spectral range. The first and second ranges include mutually exclusive first and second spectral components, respectively, and a common third spectral component which is intermediate of the other two components. The detectors are calibrated by means which include a pair of optical filters. One of the filters is a single narow band transmission which has a transmission characteristic corresponding to one of the three aforementioned spectral components. The other filter is a double, i.e. two, narrow band transmission filter which has a transmission characteristic corresponding to the other two spectral components. In this way, the number of calibrating filters used in the system during the calibration mode is minimized and simplified than would otherwise be the case if a separate filter for each of the three spectral components were to be utilized.

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.

Abstract: A spectrophotometer is operative to measure or analyze the colors of materials such as textiles. A test sample is held by a holder and is illuminated by polychromatic light. Diffuse light reflected from the sample is collected and converted to variable monochromatic light and detected. The system is calibrated by using a secondary white standard calibrated against a primary white standard, by using a black standard to compensate for dark current and internal reflectance from a pressure plate, and by using a mirror to obtain internal wall reflectance used in a correction factor.
