text: a spectrophotometer is a spectrometer that measures light intensity (key term-photometer) at some wavelength(s).a wavelength scan, whether performed all at once (using a multi-element ccd) or sequentially (by moving a prism or diffraction grating), is generally made with a scanning spectrophotometer (measuring absorbance profile).
