K3 Camera


K3 Camera

Top of the range direct detection camera

The Gatan K3 sets a new benchmark for imaging performance for direct detection cameras. It’s optimised for demanding low-dose applications in both life science and materials science. The K3 camera is the top of Gatan’s range of real-time, single electron counting direct detection cameras.

  • Powerful inline signal processing raises the DQE beyond the K2 camera
  • No need to save terabytes of raw frames, with optional inline, GPU-based motion correction
  • Large 24 megapixels (5,760 x 4,092) field of view; 1.6 times the size of the K2 camera
  • 3.75 times the speed of the K2 camera, with 1,500 full frames per second

The K3 camera was used to create the first 3D atomic-scale map of coronavirus – more info…

If you already have a K2 camera with a K3 upgrade, you are eligible to get the GPU option for free.

Why is Frame Rate Important in Cryo-EM?

Frame rate helps with motion correction in cryo-electron microscopy. The video below compares a high frame rate of 250 fps with and an exceptionally fast frame rate of 1500 fps on the K3 camera. The resulting image is clearer and more defined.
