A color measurement instrument with improved sample targeting or positioning. The system includes an integrating sphere, a beam splitter, a video camera, and a spectrograph. The beam splitter is aligned with the viewing port of the spectrophotometer to deliver the light reflected from the sample to both the video camera and the spectrograph. The video camera provides an image of the position of the sample with respect to the viewing port of the sphere, enabling the visual observation and evaluation of the sample position prior to use of the spectrophotometer.
