Point-of purchase (POP) spectrophotometer for open-view measurement of a color sample

A housing assembly for a point-of-purchase spectrophotometer for open-viewing measurement of a color sample, comprising:

• support means at least partially defining a target plane with a target location;
• and
• a chassis in secured arrangement with said support means such that said chassis and support means are configured to, in use, space said chassis apart from the target plane for open-viewing of the target location, said chassis configured to position (i) an illumination line of sight of a first illumination optical system toward the target location at substantially about forty-five degrees with respect to the target plane, and (ii) an imaging line of sight of an imaging optical system toward the target location at substantially about ninety degrees with respect to the target plane;
• said chassis being further configured to position at least one additional line of sight comprising at least one of (i) a second illumination line of sight of a second illumination optical system toward the target location, at substantially about forty-five degrees with respect to the target plane, and at substantially about ninety degrees with respect to the illumination line of sight as measured about the imaging line of sight, (ii) a sheen line of sight of a sheen detection system toward the target location, at substantially about forty-five degrees with respect to the target plane, and at substantially about ninety degrees with respect the illumination line of sight, and (iii) a camera line of sight of a camera system toward the target location.
