Point-of purchase (POP) spectrophotometer for open-view measurement of a color sample
First Claim
1. 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.

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.

9. A point-of-purchase spectrophotometer for open-viewing measurement of a color sample, comprising:
-
a plurality of optical systems having lines of sight directed toward a target location of a target plane, said optical systems providing depth-insensitivity associated with a depth; a housing assembly containing the optical systems and at least partially defining a position of the target plane, said housing assembly spacing apart said plurality of optical systems from the target plane; and an alignment device in secured arrangement with said housing assembly so as to be configured to be positioned between said plurality of optical systems and said target plane and to be spaced apart from the target plane by the depth, said alignment device defining an aperture proximal the target location. - View Dependent Claims (10, 11, 12, 13)

14. A point-of-purchase spectrophotometer for open-viewing measurement of a color sample, comprising:
-
an illumination optical system having an illumination line of sight directed toward a target location of a target plane; and an imaging optical system having an imaging line of sight directed toward the target location; wherein the imaging optical system includes a targeting optical system for (i) defining a perceived target size associated with the target location, and (ii) projecting light toward the target plane to define a size of the target location for user-identification thereof; and wherein the targeting optical system includes a switchable aperture assembly. - View Dependent Claims (15, 16, 17, 18, 19, 20)
