Summary:A spectrophotometer 10 providing a sample measurement area of selectable size includes a sphere 18 defining a sample station 42, a lamp 50 to illuminate the interior of the sphere 18 and therefore the sample station 42, a color measurement engine 20 including an aperture directed toward the sample station 42, and a measurement area size selector 22. The size selector 22 includes a movable plate defining two or more holes 24,26 of different sizes. The plate 22 can be moved so that only one of the holes 24,26 is aligned with the aperture to control the size of the measurement area sampled by the color measurement engine 20.
