Abstract
Disclosed herein is a point-of-purchase (POP) spectrophotometer for open-viewing of a color sample. The POP spectrophotometer includes a housing assembly containing an illumination optical system and an imaging optical system in desired orientation. Also provided is at least one of a second illumination optical system, a sheen detection system, and a camera system. The housing assembly includes a chassis in secure arrangement with a plurality of supports that define a target plane having a target location and that space the chassis therefrom. The chassis is configured to position the illumination, imaging, sheen detection, and/or camera systems in desired orientations relative to the target location and each other. The POP spectrophotometer can include an alignment device and/or targeting optics for facilitating user-identification of the target location, and means can be provided to enhance insensitivity to ambient light and/or depth variation of the color sample.
