Abstract: In accordance with one or more implementations of the apparatus, system and methods described, a sample measurement device is provided that is configured to measure the color of a sample. The sample measurement device includes at least one light source configured to illuminate the sample; at least one light sensor configured to output a signal in response to light emitted by light source and reflected off the sample being received by at least a portion of the light sensor; and a processor configured to receive the signal and calculate a color value for the sample, the processor configured to calculate the color value by at least adjusting the signal using a calibration factor.

Abstract: In accordance with particular implementations of the invention described herein, a sample for analysis is illuminated under each of one or more narrow-band light sources. The light incident upon this sample is received by a sensor that generates measurement data in response thereto. One or more processors are configured to receive the measurement data and derive an excitation response curve and a fluorescent response curve from the measurement data. The processor is further configured to generate a fluorescent profile value using measurements from the fluorescent response curve for each of the captured narrow band measurement data and an excitation profile value corresponding to the area under the fluorescence curve divided by the area under the excitation curve. The generated fluorescent profile and excitation profile are both output as a dataset providing improved measurement values over similar approaches in the art.

Abstract: In one example, an initial transform is stored for converting wavelength channel responses of a color measurement instrument to color readings. The initial transform is set in-factory by a manufacturer of the color measurement device. A color selection of a sample is subsequently retrieved from a database, where the color selection was made by an end user in response to a color reading by the color measurement instrument using the initial transform. An adjustment to the initial transform is calculated using the color selection. The adjustment is then sent to the color measurement instrument for use in making future color measurements.

Abstract: An apparatus and method for providing a solution that enables technicians or other technical professionals to obtain accurate gloss, haze and DOI values for a reflecting sample due to the surface conditions of the sample. The apparatus and method allow for the generation of a data model of the surface of a sample using a sensor array designed to detect the divergence of a collimated beam of light reflected off the surface of the sample. The same principle enables technical professionals to obtain accurate haze and clarity values for a transparent or translucent sample that is trans-illuminated by light.

Abstract: A system and method are disclosed for correcting the color of microscope images for different illuminants. The system includes a microscope having at least one image setting value selector with a plurality of pre-set positions, and an optical train having a distal end and a proximal end and being configured to convey illumination. The optical train is further configured to allow introduction of a calibration slide into the optical train of the microscope at a plurality of possible positions, each position being a conjugate plane of the sample plane, when the sample is in focus. The calibration slide incorporates an integral transmission filter array of known transmission values.
