Abstract: A monochromator having a corner mirror scanning wheel and a fixed baffle adjacent the scanning wheel to vary the effective height of an exit slit. The height profile of the baffle is adapted to selectively vary the radiant energy passed through this exit slit at different wavelengths so as to provide the desired balance among resolution, signal-to-noise ratio and the dynamic range of the background signal over the scanned portion of the spectrum.
