Abstract
A spectrophotometer wherein in order to set the instrument to a designated wavelength, the monochromator is first set to the designated wavelength position intended to be as such on the monochromator, and the entrance and exit slits of the monochromator are widened so as to measure a beam of light having a spectrum with an emission line at the designated wavelength, and the sensitivity of the light measuring circuit is so adjusted that the output therefrom is kept at a predetermined constant level, and then the slits are narrowed, whereupon wavelength scanning is conducted over a range of wavelengths including the designated wavelength so as to detect a peak in the emission line spectrum, and then the dispersing element is set to the detected peak position. A microcomputer controls the above operation in a sequential manner.
