PI-MTE: 2048B
2048 x 2048 imaging array | 13.5 x 13.5 µm pixels
The PI-MTE: 2048B from Princeton Instruments is an innovative, high-sensitivity imaging system designed to deliver scientific
performance inside high-vacuum chambers over long operation times. The PI-MTE: 2048B incorporates a back-illuminated
CCD without AR coating for ultra-low-energy X-ray detection. With 13.5 x 13.5 µm pixels and 100% fill factor, this
system offers a large imaging area with very high spatial resolution and dynamic range. The thermoelectrically cooled
design features PCBs, thermally linked to the circulating coolant to provide reliable operation inside vacuum chambers. The
system’s compact size and flexible tubing facilitate the positioning of the detector in limited space or on a movable arm.
