K3 IS Camera


NEW K3 IS Camera

World’s first counting, high-speed, large format camera for in-situ microscopy

The Gatan K3 IS in-situ TEM camera extends the K3’s “resolution revolution” to the field of materials science. With the highest in-situ signal-to-noise possible, you can now count single electrons in real time with unprecedented temporal resolution.

K3 IS gives you low-dose imaging capabilities, for access to undiscovered details during in-situ environmental reactions and beam-sensitive material research.

  • High Quality Images
    • Superior DQE for challenging low-dose and in-situ applications
    • Counted, low-dose images without beam artefacts
    • Usable individual frames – store as DigitalMicrograph images
  • Unmatched Resolution and Field of View
    • 3.7x improved frame rate compared to the K2
    • Choose 14 or 24 megapixels (up to 5,760 x 4,092)
    • 75 fps at full sensor resolution and 1200 fps with sub area (no binning required)
  • Fast Results
    • Preview results in your microscope
    • Store up to 90 minutes of continuous data
    • Use Gatan Microscopy Suite for processing, including In-Situ Player for cropping, drift correction, averaging (with frame alignment), tracking individual particles and more
    • Output data in standard video formats with timestamps

K3 IS vs Rio

This video of hydroxycancrinite zeolite compares results from the K3 IS direct detection electron counting camera and a traditional CMOS camera, the Gatan Rio 16 IS.

In-Situ Microscopy

Discover new details in your in-situ TEM experiments with up to 1200 fps, a large field of view and unprecedented sensitivity. The K3 IS provides the same electron counting performance of the K3 camera, with the added ability to capture counted data continuously. Take advantage of all the same counting benefits during in-situ experiments:

  • Single electron detection
  • Eliminate noise sources
  • Higher DQE
  • Dose fractionation
  • …and more

In the example below you can observe alloy dissociation during heating, taken with the K3 IS camera together with an in-situ heating system.

Data was acquired at a low electron dose rate of  27 e-/Å2/s and a total electron dose of only 3240 e-/Å2.

How Electron Counting Works

A quick video (<2 minutes) explaining the principle of electron counting and how it delivers the highest resolution results for single particle cryo-electron microscopy.

Example Experiment: Human Tooth Enamel

In this 4D STEMstudy of human tooth enamel, the K3 IS’s low dose imaging delivered high quality images with minimal beam damage at room temperature. This enabled studies of how the structure of the enamel relates to its mechanical properties.
