Contact now Product Sheet Skip menu Quick navigation Features Applications Options Contact Features & Benefits Modular design: Interchangeable OSL stimulation units (up to 3 wavelengths per OSL), accommodates up to 4 detection units and up to 3 irradiation sources No crosstalk: Independent operation of measurement chamber and sample reservoir ensures absence of both stimulation and radiation crosstalk Nonstop operation: Ability to load and unload samples while another sample is undergoing analysis/treatment inside the measurement chamber Flexibility: Software controlled switch of detection filters within a measurement sequence Homogeneity: Highly homogeneous and stabilized optical stimulation provides identical measurement conditions Accessibility: IP based system allows remote operation and technical support from anywhere in the world Easy upgrade: Modular design allows future expansion of device capabilities by easily adding components Reference list – TL/OSL reader Applications Thermoluminescence (TL) Thermoluminescence (TL) is a backbone in radiation protection dosimetry with a long tradition and used for a wide range of dosimetric purposes, including accident dosimetry, retrospective… Learn more Photo/ Optically Stimulated Luminescence (PSL + OSL) Photostimulated Luminescence (PSL or POSL) is also called Optically Simulated Luminescence (OSL) and can be used for a wide range of dosimetric purposes. It is gaining importance in radiation… Learn more Radioluminescence Luminescence emitted during exposure to ionizing radiation can be employed for online dosimetry, e.g. in brachytherapy.Al2O3:C or BeO attached to optical fibres for online dosimetry can serve… Learn more Neutron dosimetry Active dosimeters, like rem-mteters, superheated emulsions and electronic personal dosemeters can be used to measure neutron fields. But frequently passive dosemeters are used to determine… Learn more Food Irradiation Control Food stuff often is irradiated with ionizing radiation for sterilisation purposes. This requires the detection and estimates of the applied doses. The attached mineral dust or the food itself… Learn more Medical dosimetry Ionizing radiation from a large variety of isotopic sources, as well as accelerators, electron beams, etc. are increasingly used in radiotherapy. Clinical diagnostics employing ionizing radiation… Learn more Luminescence spectroscopy Luminescence spectroscopy is used to investigate the luminescence properties of materials and thus allow more precise definitions e.g. of measurement parameters (e.g. detection ranges). It can… Learn more Spatially resolved luminescence Measuring luminescence with EMCCD camera allows for the spatial differentiation of luminescence signals. Different minerals, mineral phases, radiation hot spots etc. can be determined in granular… Learn more Time resolved luminescence Time resolved luminescence measurements allow the determination of the life-times of electron states and thus description of the kinetics involved. This allows the correlation to different… Learn more Optically stimulated Luminescence dating of quartz (OSL) Age range, Few years (depending on signal intensity and sensitivity of equipment for which the lexsyg systems are especially developed), Up to ~150-200,000 years (depending on dosimetry),… Learn more Infrared stimulated Luminescence dating of feldspar (IRSL) Due to higher saturation doses the age range is larger than for OSL, Internal dose rates in K-feldspar reduce dependency on external dose rate and water content, Might suffer from an anomalous… Learn more Single grain/spatially resolved luminescence dating Not every grain in a sediment sample reflects the same last bleaching and burial history. By analysing single mineral entities (whether grains or parts of it) different dose populations can be… Learn more Radiofluorescence Infrared-Radiofluorescence (IR-RF) is a technique for dosimetric dating of potassium feldspar to establish sedimentation ages. This method avoids some of the problems of other trapped-charge… Learn more Pulsing: mixed mineral samples Sometimes mineral separation in sediment or solid samples is not possible (polymineral samples), especially in cases of intergrowth of minerals. Pulsing (i.e. short light stimulation) the… Learn more Flint and other heated rocks Rocks containing amorphous/microcrystalline SiO2 can be dated by luminescence methods when they have been heated to approximately 400°C. Such temperatures, whether accidentally or deliberately,… Learn more Ceramics, pottery, bricks and statues While the typology of ceramics is a backbone of many archaeological chronologies, establishing the age directly for certain types of ceramics is sometimes required. Optically Stimulated… Learn more Unheated rock surfaces Granite or other quartz/feldspar containing rocks are preferentially dated with spatially resolved luminescence, Marble, limestone surfaces are dated with Optically Stimulated Luminescence (OSL)… Learn more Sediment dating Optically Stimulated Luminescence (OSL, TT-OSL) dating of quartz grains from sediments, Infrared Stimulated Luminescence (IRSL, pIRIR, IR-RF) dating of feldspar grains from sediments, Trench… Learn more Interested?
