An ultra-fast, event-based electron detector for transmission electron microscopy (TEM). Its data-driven mode, and noise-free readout enables up to 1000x faster acquisition with far smaller datasets, supporting 4D-STEM, ptychography, time-resolved EELS, and ultrafast TEM with nanosecond timing and low-dose sensitivity.
The Detectors Behind your discovery!
CheeTah is an electron detector for advanced electron microscopy that needs fast acquisition, precise timing, and efficient data handling. By recording only meaningful electron events, it reduces data volume while improving acquisition speed and experimental flexibility.
Its event-based architecture supports 4D-STEM, ptychography, ultrafast TEM, and in situ experiments. Combined with nanosecond timing, high-speed streaming, and low-dose sensitivity, it lets researchers study dynamic processes, sensitive materials, and transient phenomena in detail.
Key features
High-speed diffraction mapping for strain, orientation, and electric-field analysis.
Phase reconstruction with efficient electron usage.
Characterization of beam-sensitive materials such as 2D materials and soft matter.
Real-time monitoring during heating, biasing, or mechanical testing.
