Electron detectors


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.
