Laboratory and Field — Lexsyg

Explore how the Lexsyg Research Imaging TL-OSL-RF System supports high-throughput luminescence dating in geochronology and archaeochronology. Designed for advanced TL/OSL work, it offers modular stimulation, powerful detection options, and the flexibility needed for modern dating laboratories.

Understanding Thermoluminescence (TL) and Optically Stimulated Luminescence (OSL) in Scientific Research Thermoluminescence (TL) and Optically Stimulated Luminescence (OSL) are well-established analytical techniques used in geological dating, radiation dosimetry, and materials research. This article explores the physical principles behind TL and OSL, common scientific applications, and the role of modern instrumentation in supporting controlled luminescence measurements. What Are TL and OSL Techniques? Thermoluminescence (TL) and Optically Stimulated Luminescence (OSL) are methods used to measure light emitted from certain materials after exposure to ionizing radiation. These techniques are based on the behavior of trapped charge carriers within crystal lattice defects. When minerals...

Overview For years, the Risø DA-20 TL/OSL Reader has been the most widely recognized instrument in luminescence dating and retrospective dosimetry. It’s familiar, reliable, and has a long track record. But as research has advanced, so have the demands placed on instruments. The Risø’s fixed protocols, limited stimulation options, and single-detector setup now restrict what many labs want to accomplish (Risø Reader Documentation). That’s why more researchers are turning to the Lexsyg Smart and Lexsyg Research from Freiberg Instruments. These next-generation readers were designed to overcome the limits of older systems—delivering programmable heating, modular stimulation, advanced detection, and homogeneous irradiation...
