A target acquisition attachment device for the accurate handheld spectrophotometric measurement of small samples or samples of particular areas of larger objects, having an orifice in its base plane of precise location and size that will properly align with the aperture of the handheld spectrophotometer. The alignment occurs when the target device is first placed over the small sample and subsequently, the handheld spectrophotometer is placed within the peripheral dimensions of the target device. This alignment of the handheld spectrophotometer's aperture within the peripheral dimensions of the small sample can be achieved even when the sample becomes no longer visible to the spectrophotometer operator due to the handheld spectrophotometer's placement over the small sample being targeted for measurement.
