The exciting new TEM CMOS camera XAROSA B20T delivers more than 30 frames per second with its full 20 megapixel and sets a new benchmark in speed, resolution and price / performance.

XAROSA is up to 30 frames per second at its full 20MP and uses the latest Thunderbolt interface to deliver high-quality and high-speed data to workstations. Using pixel merging can also achieve higher speeds.

In addition, proven, pyramidal fiber technology enables pixel size, perfect match between fiber and scintillator. XAROSA uses high-quality and customized prismatic fibers that provide both very high photon sensitivity and a wide field of view. CMOS image sensors produce no ghosting, making them ideal for photographic imaging.

Combined with our advanced imaging software RADIUS, XAROSA offers a wide range of capabilities including video recording, HDRI, averaging and drift correction, as well as one-click centering, fully interactive / automated measurement and comprehensive image database.
