CheeTah Product Family Configurations Options Image

CheeTah detectors are advanced hybrid pixel detectors for transmission electron microscopy applications. Enabling the full power of Medipix 3 and Timepix 3 technology, CheeTah detectors allow data acquisition with single electron sensitivity combined with high speed and noiseless data acquisition.

CheeTah is the detector of choice for low-dose applications and for beam-sensitive materials!

The CheeTah can be mounted or retrofitted on any TEM manufactured by ThermoFisher, JEOL, Hitachi and Zeiss.

Key Features

Noise-free and ultra-sensitive direct electron detection
Smallest pixel size (55 µm) for best resolution at small working distance
Long-term radiation hard - don't be afraid to focus the beam on the detector
Numerous electron counting modes and bit depths
Can be used for all modern TEM applications such as 4D-STEM, U-EELS, U-TEM or 3D-ED
Frame rates up to 12.000 fps (Medipix-3) or event timing down to 260 picoseconds (Timepix-3)
