title: Spectrometer slit programmer with no moving parts.
abstract: An optical system with no moving mechanical parts has been installed in a rapid scanning spectrometer to program the spectral slit width as a function of wavelength. A set of contoured slits and baffles maintains a good balance between signal and resolution and keeps the dynamic range of the background signal within reasonable limits.
