ABSTRACT:
A spectrophotometer for measuring a two-dimensional area or a spot area in a rather broad surface of a sample, where the spectrophotometer is provided with a camera for taking the picture of the sample surface. The picture is shown on a display screen, and the operator can move a window superimposed on the sample picture in the display screen by using a mouse or the like to a desired place on the sample surface. The sample stage on which the sample is mounted moves according to the movement of the mouse, whereby a spectrophotometric measurement of the desired place (two-dimensional area or the spot area) on the sample is facilitated.
