Contact now Product Sheet Skip menu Quick navigation Features Applications Options Software Contact Features & Benefits Compact design: provides thermal and optical stimulation for up to 3 different wavelengths No crosstalk: independent operation of measurement chamber and sample changer ensures absence of stimulation and radiation crosstalk 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 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 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 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 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?
