Abstract: A color measurement instrument includes a housing and illuminators, a two-dimensional photodetector array, and an optics system within the housing. A UV filter wheel closes the housing to prevent contaminants from entering the housing. The filter wheel supports UV filters and non-UV glass that can be selectively aligned with the illuminators.

Abstract: A system and method for identifying primary color chromaticity coordinates of a red, green and blue light sources includes a tristimulus filter the receives the combined light generated by the light sources. The light sources are preferably a group of red, green and blue light emitting diodes. A processor is configured to generate a plurality of test control signals that sets a desired intensity value for each of the red, green and blue LEDs. Based on these test control signals, the system is configured to measure three sets of chromaticity coordinates corresponding to the combined light generated by these red, green and blue LEDs. The processor thereafter calculates the color chromaticity coordinates of the LEDs, based on the measured coordinates of the combined light, and the intensity values of the LEDs, and the intensity values of the combined light. This calculation in accordance with one embodiment of the invention is accomplished by solving a matrix equation. Once the color coordinates of the individual light sources is uniquely calculated, the system measures the intensity values of light for each of the light sources that is necessary to provide a combined light with a desired color chromaticity coordinates. These intensity values can be used in a feedback control circuit to maintain the desired combined light as the LEDs change their characteristics from batch to batch or over time.

Abstract: A colorimeter capable of calibrating color monitors, whether having cathode ray tube or liquid crystal (LCD) displays, is provided by a photometric array of photodetector (38) and optical filter (50) pairs. The filters (50) include long-pass, edge filters which cover overlapping regions at the upper end of the visible spectrum and a filter which covers the entire visible spectrum. The outputs of the photodetectors (38) are digitally synthesized to provide a response which mimics the response established by the Commission Internationale de l'Eclairage (CIE) xyz (bar) functions almost perfectly. The response which is mimicked may be represented by the CIE color matching functions. The pairs (38, 50) and the associated components are mounted on a printed circuit board (32) captured in a clamshell housing (12, 14) and having an array of apertures (20) which define angularly constrained fields of view of a surface from which the light, to be colormetrically analyzed, emanates.
