A new scanning monochromator was designed to investigate the wavelength-resolved luminescence excitation and emission characteristics of quartz and feldspar samples; results are presented together with detailed measurements of the thermal activation energies required for luminescence stimulation in feldspar over the wavelength range 400-1000 nm. When coupled to automated dating equipment, we demonstrate that optical characteristics of sample selected for dating can be routinely measured, or more detailed analysis of physical processes can be made.
