    Abstract: A spectral colorimeter includes an integrating sphere light source for projecting a beam of illuminating light to a sample, a light intensity sensor for receiving light reflected from the sample, a spectral characteristic calculator for calculating a spectral characteristic of the sample based on light reception data. The calorimeter is provided with a positional displacement detector for detecting a positional displacement of an illuminated spot of the sample and a corrector for correcting a calculated spectral characteristic based on a detected positional displacement of the illuminated spot. The spectral characteristic of the sample can accurately be obtained irrespective of a distance variation.

    Abstract: There is provided a high precision device for measuring the color of non-self-luminous or self-luminous objects having interchangeable optical geometries for conversion from one optical geometry to another. The device interchanges a plurality of modules, each having at least one optical geometry for directing illumination from an illumination source and for collecting sample light reflected from a measured object or sample. Such optical geometries include a 45/0 geometry, sphere geometry, specular included geometry, and specular excluded geometry. Each module is removably attached to the device when measurement of the color of the sample is desired and may be separated from the device when measurement of the color of the sample is not desired. Also, each module may include removable filters for absorbing certain types of light, such as ultraviolet visible light, and blocking elements to determine the source of any reference signal. The device may further include a sensing system that automatically determines which module has been installed and to appropriately configure the device.

    Abstract: A device and method for grading gemstones. The device utilizes an band pass filter and detector array to obtain the spectral response of a complete image. The gemstone is illuminated in a way that provides for analysis of both reflected and transmitted light. The device utilizes multiple lighting angles to construct an composite image that is used to perform the grading of the gemstone. The device provides spectral photometric data for each individual pixel of the image, or any portion of the gemstone image.

    Abstract: A digital, abridged spectrophotometer with a detecting head defining a roughly spherical, reflective inner surface broken by a viewing port and a light source port with a number of filtered photodiodes mounted in the head for each receiving light from a sample or standard in the viewing port. A standard sheet of vitrolite is mounted on the housing for movement with a plunger, which trips a switch, to cover the viewing port, while a standard black sheet can be pivoted to cover the viewing port for the calibration which precedes each reading. A digital computer calculates the tristimulus values from the signals produced by the photodiodes and provides signals for a display of the color values.
