Lexsyg Research: Advanced Luminescence Reader for Geochronology & Archaeochronology For luminescence dating labs, choosing the right TL/OSL reader is critical. The Lexsyg Research Imaging TL-OSL-RF System is designed for high-throughput, method-flexible work in geochronology and archaeochronology—designed to support TL, OSL, RF, RL, and imaging measurements in a modular research platform. What Is the Lexsyg Research Imaging TL-OSL-RF System? The Lexsyg Research is a fully featured luminescence reader developed by Freiberg Instruments and distributed by Rotunda Scientific Technologies. It is designed for research-grade thermoluminescence (TL), optically stimulated luminescence (OSL), and radiofluorescence (RF) measurements in a single instrument platform. At its core, Lexsyg Research is a modular TL/OSL reader with: Thermal stimulation for TL measurements with precise, programmable heating profiles. Optical stimulation (OSL/IRSL/PSL) using interchangeable units that can host multiple stimulation wavelengths. Support for multiple detection units, including high-sensitivity photomultiplier tubes and EMCCD-based imaging options. Optional integrated irradiation sources and uniform, controlled stimulation fields for reproducible measurements. The system separates the sample storage wheel from the measurement chamber, reducing optical and radiation crosstalk and enabling continuous operation: samples can be loaded and unloaded while another aliquot is being measured. View Product Page Why Geochronology & Archaeochronology Labs Choose Lexsyg Research In Quaternary geology and archaeochronology, luminescence dating—especially OSL dating of sediments and TL/OSL dating of heated materials—is a core method. Labs need TL/OSL readers that can handle: High sample throughput for large dating projects. Flexible stimulation and detection options for different minerals (quartz, feldspar, ceramics, glasses). Stable, repeatable measurement conditions for robust equivalent dose estimates. Lexsyg Research was designed with these requirements in mind. It supports routine multi-aliquot measurements for dating projects, as well as advanced protocol development and exploratory work on new luminescence signals. For labs transitioning from older systems, Lexsyg Research provides modern control software, automated sequences, and a hardware architecture tailored to mass measurements without sacrificing experimental flexibility. Typical questions that bring geochronologists and archaeochronologists to Lexsyg Research include: “What is the best TL/OSL reader for luminescence dating?” “How can I upgrade from a legacy Risø system to a next-generation TL/OSL reader?” “Which instrument supports high-throughput OSL and TL with flexible protocols and multiple wavelengths?” Key Capabilities for Luminescence Dating & Dose Reconstruction For labs searching for a “TL/OSL reader for luminescence dating,” “OSL dating system,” or “luminescence dating instrumentation,” the Lexsyg Research Imaging TL-OSL-RF System offers several capabilities that directly address these needs: Support for TL, OSL, RF, RL, and related luminescence methods – Depending on configuration, the system can support conventional TL, continuous-wave and modulated OSL, infrared-stimulated luminescence, RF/RL, and related applications across dating and dosimetry workflows. Modular stimulation units – Interchangeable OSL heads can contain up to three stimulation wavelengths (for example, violet, blue, and infrared), enabling optimized excitation for quartz and feldspar and facilitating protocol development. Multiple detection channels – Configurations with photomultiplier tubes for different spectral ranges and EMCCD imaging options support both integrated and spatially resolved (single-grain or multi-grain) measurements. High-throughput sample handling – Large sample storage wheels, separated from the measurement chamber, allow sequential measurement of many aliquots with minimized crosstalk and reduced handling time. Continuous operation – While one sample is being heated or optically stimulated, additional samples can be loaded or unloaded, keeping the instrument productive throughout the day. Homogeneous stimulation fields – Designed to provide uniform illumination across the sample area, supporting consistent dose–response work and protocol inter-comparisons. Remote access & software control – IP-based control and modern operating software make it straightforward to manage experiments, update sequences, and support remote diagnostics. Together, these features make Lexsyg Research a strong candidate for labs that need both routine dating capabilities and the freedom to push luminescence methods into new areas of research. How OSL/TL Labs Use Lexsyg Research in Practice In day-to-day work, geochronology and archaeochronology groups typically use Lexsyg Research for: OSL and IRSL dating of sediments – Running standard SAR, pIRIR, and related protocols on quartz and feldspar, including preheat tests, dose-recovery tests, and dose–response curve generation. TL dating and firing temperature studies – Measuring TL signals from ceramics, burnt stones, and baked sediments to determine firing temperatures or burial ages. Protocol development and method testing – Exploring new stimulation sequences, temperatures, and filters; studying signal components; and investigating bleaching behavior and anomalous fading. Retrospective and accident dosimetry – Measuring luminescence from dosimetric materials, glasses, or ceramics for dose reconstruction in radiation-exposure scenarios. Quality assurance and irradiated food testing – Supporting laboratories that test for irradiation treatment of foods under relevant standards using luminescence methods. Because the system is designed for both routine mass measurements and detailed experimental work, a single Lexsyg Research setup can handle baseline dating projects, inter-laboratory comparison studies, and cutting-edge luminescence research. Choosing a TL/OSL Reader: When Lexsyg Research Is the Right Fit When labs compare “Lexsyg vs. other TL/OSL readers,” the decision often comes down to three questions: Do we need high throughput for OSL/TL dating projects? Do we want the flexibility to design and refine complex luminescence protocols? Do we need a platform that can grow with our research (additional stimulation wavelengths, detectors, imaging, or radioluminescence)? Lexsyg Research is particularly well suited when the answer to all three is “yes.” Compared with legacy systems, it provides: A modern hardware architecture with modular stimulation and detection. Improved homogeneity and control over stimulation conditions. Automation features that reduce manual handling and operator workload. For many geochronology and archaeochronology labs, this combination of throughput, flexibility, and upgradability makes Lexsyg Research a long-term platform rather than a single-project instrument. Final Thoughts The Lexsyg Research Imaging TL-OSL-RF System is a modern modular luminescence reader designed for the realities of geochronology and archaeochronology research: large sample sets, evolving protocols, and the flexibility to support TL, OSL, RF, RL, and imaging measurements depending on configuration. For laboratories searching for a “advanced TL/OSL reader for luminescence dating,” “advanced OSL dating system,” or “high-throughput TL/OSL reader for Quaternary research,” Lexsyg Research offers a comprehensive, modular solution that can support both routine dating programs and experimental luminescence research.
