DXF 200 - High Speed Xeon-Pulse Delivery Source and Solid State Pin Detector for Unmatched Sensitivity Down to -150 °C

The Discovery Xenon Flash DXF 200 features a patented High-Speed Xenon-pulse Delivery™ source (HSXD) and an anamorphic multi-faceted Light Pipe™. Together, these optics deliver a light pulse of unsurpassed power and uniform intensity to the specimen, while preventing sample holder over-flash. The DXF 200 employs a solid-state PIN detector that enables high-sensitivity measurements under cryogenic conditions. Only TA Instruments High-energy Xenon design is capable of testing samples to a diameter of 25.4 mm over a temperature range from -150°C to 200°C. The use of large samples diminishes errors associated with inhomogeneity and permits representative measurements of poorly dispersed composites. The DXF platform is designed for research and development programs as well as production control.

Key Features
