K3® IS – The world’s only counting, high-speed, large-format camera for in-situ transmission electron microscopy (TEM). With an unprecedented temporal resolution, this true next-generation camera collects the ultimate in-situ data to extend the K3’s resolution revolution into material science.


  • See your sample, not beam-induced artifacts
  • Capture the highest-quality, low-dose, in-situ video with the industry-leading DQE and sensitivity


  • Count single electrons at unsurpassed speeds
    • 150 frames per second (fps) at full field of view
    • >3500 fps at 256 x 256 pixels
  • Shorten time to results with the market-leading Gatan Microscopy Suite® (GMS) in-situ processing utilities and free offline tools


  • Expand the field of view to 14- or 24-megapixels – Up to 1.65 times the size of the K2® IS camera
