K3™ IS – The world’s first counting, high-speed, large-format camera for in-situ microscopy. Extending the resolution revolution from K3 into material science, you can now count single electrons in real-time with an unprecedented temporal resolution to collect the ultimate in-situ data. The K3 IS enables not only low-dose imaging via real-time electron counting but also makes possible new experiments to study in-situ reactions of beam-sensitive materials.

Highest image quality

  • Superior DQE is required for the most-demanding low-dose and in-situ applications
  • See your sample, not beam artifacts with counted, low-dose images

Unsurpassed resolution and field of view

  • Counts 3.7x the electrons per second of the K2®
    • K3 IS (model 1027) – 24 megapixels (5,760 x 4,092)
    • K3 Base IS (model 1026) – 14 megapixels (3,456 x 4,092)
  • Store 150 fps at full sensor resolution, and >3500 fps with sub-area readout

Shortest time to results

  • Ensure you collect the best data possible by quickly previewing results at the microscope
  • Minimize time to results with well-established Gatan Microscopy Suite® (GMS) in-situ processing utilities, including free offline tools

K3 IS: Low dose EM meets catalysis


Continuing our prosperous collaborations that built the K2, the K3 is the successful result of Peter Denes' team at Lawrence Berkeley National Laboratory and David Agard.
