Abstract
A self-contained automatic computer controlled system for checking and recalibrating the wavelength scale of both monochromators of a fluorescence spectrophotometer is described. No operator adjustments are required. The system sets the wavelength of each monochromator to within 0.1 nanometers. Besides automatic indexing at turn-on the operation can be repeated at any desired time. The system is applicable to single or double monochromator instruments.
