COLOR MEASURING HEAD AND SCANNER DEVICE EQUIPPED WITH SAME

摘要

PROBLEM TO BE SOLVED: To improve a color measuring head and a scanner device including it to make them suitable for performing very accurate measurement. SOLUTION: The scanner device includes: a support surface for a measured object; a drive unit for moving a color measuring head over the support surface in at least one dimension thereof and for adjusting the height of a color measuring head in the direction perpendicular to the support surface; and a measuring and drive control unit for activating the drive unit and co-operating with the color measuring head MH. The color measuring head MH has at least an illuminating channel IC and a collection channel CC. The illuminating channel IC has a light source 10 and optical means 12-22 for illuminating a measured object S at a measurement site at a mean angle of incidence of 45E. The collection channel CC has optical means 24-34 for capturing the light emanating from the measured object at the measurement site at a mean collection angle of OE and coupling it into a light guide LF.
