    Abstract: Spectrometer apparatus (10), for self-calibrating a color image scanner (30) of the line scanner or area scanner type, comprises a member (20), having an optical slit (18), movable into position on an optical axis (14) of the scanner between its polychromatic light source (12) and its focusable lens (16) in a plane occupied by a color image when it is scanned. A diffraction grating (24) is similarly movable onto the optical axis, a given distance from an image sensor (22) of the scanner. The light source illuminates the slit and the diffraction grating disperses transmitted polychromatic light according to its wavelength, forming duplicate spectra off-axis across respective halves of the image sensor, with longer wavelengths being diverted to respectively higher angles.
