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 in-line signal processing raises the DQE beyond the K2 camera
- No need to save terabytes of raw frames, with optional inline, GPU-based motion correction
- 1,500 full frames per second (3.75 times the speed of the K2 camera)
- Choice of two models with different sensor sizes:
- K3: Largest field of view with 24 megapixels (5,760 x 4,092). 1.6 times the size of the K2 camera.
- K3 Base: Cost-effective model with 14 megapixels (3,456 x 4,096). Turn screening microscopes into data collection instruments.
If you already have a K2 camera with a K3 upgrade, you are eligible to get the GPU option for free.
Mapping the Coronavirus
The K3 camera was used to create the first 3D atomic-scale map of coronavirus – more info…

We’d also upgraded our K2 detector to a K3 detector six months ago so for an average user like me, the key advantage here was the speed with which I could collect the movies. I think we probably doubled the number of movies that we could collect in a single day by moving from the K2 to K3.
Also, just the physical parameters of the detector itself are larger – so if you’re trying to get a greater number of particles, this means you can collect fewer movies.
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.
