ASI’s CheeTah is a hybrid pixel detector for electron microscopy applications. Enabling the full power of Medipix 3 and Timepix 3 technology, the CheeTah detector allows single electron sensitivity. Moreover, high-speed and noiseless data acquisition. Also, it offers unprecedented possibilities to boost the power of standard TEMs. The EM – CheeTah is the detector of choice for low-dose applications and for beam-sensitive materials!
The CheeTah can be mounted on any kind of TEM like ThermoFisher, JEOL, Hitachi and Zeiss.

Testimonials
“The CheeTah Medipix 3 detector combined with continuous rotation electron diffraction greatly improved the data quality and shortened the data collection time from hours to minutes. Ab initio structure determination by electron diffraction has now become as feasible as by X-ray diffraction, but from crystals thousands of times smaller than what are needed for X-ray diffraction.”
Prof. Xiaodong ZouDepartment of Materials and Environmental Chemistry at Stockholm University
“Hybrid pixel detectors, boost the power of electron diffraction!”
