We report on recent advances in the development of luminescence measurement systems and techniques at Riso. These include: (1) optical stimulation units based on new-generation powerful blue light (470 nm) emitting diodes providing up to 28 mW/cm(2) for OSL measurements; (2) an infrared (830 nm) laser diode unit providing up to 400 mW/cm(2) for stimulation of feldspars; and finally (3) an optical stimulation attachment based on a focused solid stale green (532 nm) laser for rapid OSL measurements of individual sand-sized single grains of a sample. Facilities for hearing samples during beta irradiation and performing linearly modulated OSL measurements have also been incorporated into the system.
