    Abstract: The present invention is directed to an apparatus and method for measuring the haze value of transmissive samples. The apparatus comprises a first light source selectively configurable to emit a first light beam, a second light source selectively configurable to emit a second light beam, an integrating sphere having an outer surface and an inner surface, the inner surface configured to reflect light incident upon the inner surface, the inner surface further enclosing an interior volume. The integrating sphere is further equipped with an exit port configured to emit light from the interior volume of the integrating sphere. The exit port is positioned such that light from the first light source exits the integrating sphere without obstruction, and light from the second light source is diffused on the interior surface of the integrating sphere prior to exiting the exit port. A light detector is also included and is configured to generate a light-intensity signal when light exiting the integrating sphere has passed through a sample and is incident on the light detector. The apparatus further includes a processor configured to receive the light-intensity signal and generate an output signal to a user indicating the haze value. The present invention is also directed to a method of calculating the haze value of a sample using a stored calibration value, a diffuse transmission value (sample-absent diffuse light-intensity value), a direct transmission value (sample-absent direct light-intensity value), a measured diffuse transmission value (sample-present diffuse light-intensity value) and a measured direct transmission value (sample-present direct light-intensity value).

    Abstract: In one example, an electronic signal is received from a target color measurement instrument that includes a plurality of color channels. A response of the target color measurement instrument to a light emitted by a target light emitting device is extracted from the signal. The response is calibrated to minimize a difference between the response and an output of a color matching function of a standard observer. Calibrating includes multiplying the response by a calibration matrix. The calibration matrix combines measurements of a first plurality of lights from a tunable light source and measurements of a second plurality of lights from the target light emitting device. A first subset of the measurements of the first plurality and second plurality of lights are made by the target color measurement instrument and a second subset of the measurements of the first plurality and second plurality of lights are made by a reference spectroradiometer.

    Abstract: The present invention concerns a system and method for identifying and implementing a correction to spectrometer measurements in order to compensate for errors in the measurement values due to second order diffracted light. The present invention in one configuration, measures light reflectance percentages across the same wavelength range for at least one calibration target. From these measurements the portion of the reflectance values resulting from second order diffracted light is identified and corrected for, thereby generating a compensated measurement of the reflectance values of a sample. These compensated values are then provided to a user.
