Abstract
An ultraviolet/visible/infrared spectrophotometer, with a pulsed light source (10), has a monochromator with variable slit width to provide variable spectral resolution. The dynamic range at the detectors (24, 28) is reduced by varying the pulse energy emitted by the light source (10) in accordance with the wavelength and slit width settings (34, 36), and/or by varying the slit height in accordance with the slit width. The ligth source (10) may be a xenon flash lamp.
