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: An improved sample holder for a spectrophotometer includes a stationary base that forms a cylindrical cavity and supports a fiber optic head assembly over the cavity for analyzing the color of a sample that is positioned adjacent the base and under the cavity. The fiber optic head assembly covers the top of the cavity and the area of the sample that is to be color analyzed is not visible to an operator of the spectrophotometer. A shutter mechanism is arranged to be moved in an opening in the base between a closed position in which the shutter forms part of the cylindrical wall of the aperture and an open position in which the opening in the base permits an operator to view the sample. A prism is provided to raise the viewing position of the operator to the normal position of the operator.

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: This monochromator is made up of a number of discrete narrow band interference filters mounted on a drum which rotates with respect to a light beam so that as the light beam passes through each of the filter the angle of incidence of the light beam changes with respect to the filter. Each of the filters is for a different normal wavelength of peak transmission so that spectral analysis of the light source can be obtained.

Abstract: A charge storage diode array target is provided with a resistive layer over the output side of the target over the diode portions and the area between diodes, with metal contact caps over the resistive layer over the diode portions. The target is operationally aged with input radiation sufficient to produce an output signal current density of at least about 300 nanoamps per square centimeter at a given reverse bias potential, for a period of at least 50 hours. The target thereafter exhibits high beam acceptance and low lag characteristic.
