    Abstract: Photometric analyzer having a reaction chamber for exciting samples by thermal, chemical or other energy to emit characteristic light, the reaction chamber usually being operated at elevated temperature. A photometric light sensor is located remotely from the chamber away from the influence of heat therefrom. Characteristic light is transmitted from the chamber to the photometric light sensor by a fiber optic bundle.

    Abstract: An instrument for the instantaneous measurement of the chromaticity of time variant spectral sources including a plurality of narrow band sensors or transducers that in combination encompass the visible spectrum. Each consists of an interference filter and a linear photovoltaic cell whose three output voltages have been ''''optimum multiplied'''' for the three tristimulus functions through a voltage divider network. The corresponding individual outputs of the sensors are added by a summing feedback amplifier to provide a voltage output proportional to the tristimulus values. These proportional outputs are then summed by a unity gain summing amplifier whose output in turn is applied to one input of a pair of ratio recorders. The other ratio recorder inputs each receive one of the proportional outputs. Each ratio recorder inputs each receive one of the proportional outputs. Each ratio recorder output, therefore, is one of the normalized chromaticity coordinates. The output coordinate values (x and y) are simultaneously fed into a chart recorder to derive a plot of the chromaticity coordinates vs. time. The invention described herein may be manufactured, used and licensed by or for the Government for governmental purposes without the payment to us of any royalty thereon.

    Abstract: An optical magnifying lens is mounted as part of a manually portable color printing analysis device which has support means adapted to position the lens properly above a color print surface to be inspected. A light on the device illuminates the surface, and a color filter is mounted for selective movement into the field between the lens and surface. The filter color is complementary to the color of that part of the surface to be checked. For example, a blue filter is provided for inspection of yellow printed surfaces. Preferably one or more such color filters are mounted on a filter plate movably supported on a body portion of the device, which body portion also serves as a handle and battery case. Inspection of the surface through the magnifying lens and filter provides an enlarged dark contrast image of the desired color printed areas, such as the colored dot portion of a colored halftone sheet, even though some of the colors to be inspected are partially overprinted by other colors.

    Abstract: A spectral photometer including a filter wheel driven by a synchronous motor and an analysis circuit. Interference effects of the power line on the output of the photometer are cancelled by provision of a speed changer to achieve each revolution of the filter wheel in the time required for a set, odd number of power line half-cycles to the motor.

    Abstract: There is herein disclosed a laser detector and spectral analyzer comprising a plurality of photoelectric detector elements, at least, two of which are suitably masked and disposed behind a wedge type interference filter. An additional detector element is operated without any mask or filter. The detector output signals are electronically processed to provide a substantially instantaneous and independent indication of the mean spectral wavelength, spectral width, total power and pulse length of radiant energy incident upon the apparatus.
