摘要： A tristimulus colorimeter on a single semiconductor chip having at least three detectors, each detector being coated by colorant filters, each filter having at least one layer and at least one filter having a double layer is provided. The colorimeter determines CIE tristimulus values of an incident light from inputs to the filters and detectors. Colorimeters having integral dye filters may be constructed on a single silicon chip embodying all the detectors and electronics, coated over each detector by a deposited filter layer. Colorants may be directly deposited on the detectors, rather than using a plastic substrate for a filter.

摘要： 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.
