K3 Cameras

The new imaging performance benchmark for direct detection cameras.

Advantages Research Spotlight Media Library Publications Resources Back to top

Redesigned from the ground up, this true next-generation camera is optimized for the most demanding low-dose electron microscopy (EM) applications in both life science and materials science research. The K3® camera series is the complete and latest expression of Gatan’s deep experience in the delivery of real-time, single-electron counting direct detection cameras.

  • Powerful inline signal processing will raise the DQE beyond that of the K2® camera; the addition of CDS mode pushes this even higher 
  • Real-time electron counting immediately lets you know if your samples are good 
  • Optional inline, GPU-based motion correction avoids the need to save terabytes of raw frames
  • 1,500 full frames per second –  3.75 times the speed of the K2 camera
  • Match the field of view with your application needs
    • K3 (24 megapixels) – Maximize throughput for your highest performance microscopes 
    • K3 Base (14 megapixels) – Turn screening microscopes into data collection microscopes
