| 摘要 |
The present invention relates to a color measurement device for measuring the color of a target object, the device comprising:
an illumination system including an illumination source having at least a white portion in combination with a chromatic portion, the illumination system being structured to generate light in all portions of the visible spectrum and provide spatially uniform illumination at a given target distance from the target object sufficient to spatially over-illuminate a predetermined target area on the target object, wherein the illumination system further comprises an illumination lens structured for operative association with the illumination source, the illumination lens comprising at least one optically fast lens, and at least one spatial intensity filter positioned in operative association with the illumination lens;
an optical collection system structured for non-contact color measurement of the target object, wherein the optical collection system is positioned in the device to function at a distance from the target object and receive light reflected therefrom, the optical collection system further comprising an image-based collection optic having a field stop at an image plane to define a target area plane for the target object; and
a color engine in communication with the optical collection system configured for spectrally analyzing light detected by the optical communication system.
