The Discovery Xenon Flash DXF 900 platform 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 TA Instruments High-energy Xenon design is capable of testing samples up to a diameter of 25.4 mm over a temperature range from ambient to 900°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.
