Gatan K3 Camera

Gatan K3 IS

The Gatan K3 IS is the world’s first fast, electron counting, large format camera for in-situ microscopy. The high resolution of the K3 camera is now available for in-situ materials science applications.

The ability to count single electrons at unmatched temporal resolution gives you the highest signal-to-noise in-situ results. This enables low-dose imaging and gives you access to previously undiscovered details of in-situ environmental reactions and beam-sensitive materials.

Highest Quality Imaging

Low-dose imaging and in-situ studies require excellent detective quantum efficiency (DQE). Counted, low-dose images allow you to see the details of your sample clearly, not obscured by beam artefacts.

Extending this capability to in-situ studies gives you the highest spatial and temporal resolution.

Unmatched Resolution and Field of View

The K3 IS can count 1500 full fps across 14 megapixels (4,096 x 3,456) – with 3.7 times the frame rate of K2 camera.

You can store 75 fps at full sensor resolution, or sub areas at 1200 fps with sub area, with no binning required.

Fast Results

Results can be previewed quickly at the microscope, to ensure you’re collecting the highest quality data possible. Data can then be analysed quickly with Gatan’s Microscopy Suite (GMS) software. This includes free offline tools and features.

The GMS In-Situ Player is easy to use, with a tried and tested toolset from Gatan’s established OneView and Rio cameras. This includes useful, practical settings, so you can reduce data size and focus on the results you need. The resolution in terms of both time and space can be adjusted to suit your requirements:

Reduce data size by adjusting the resolution (temporal and spatial) and duration to focus on the results you need. Dimensionality and bit depth can also be adjusted using scripting.

Benefits of Electron Counting

Electron counting gives you clearer, better quality results by:

  • Eliminating variability from scattering events
  • Removing electronic read-out noise / background signals
  • Delivering the highest signal-to-noise output (DQE)

Analyse Beam-Sensitive Materials

With the ability to study beam-sensitive materials, the K3 IS reveals structures that may not have been visible before – and you can also study how they react in in-situ experiments. This is a unique benefit of electron counting cameras, possible because of the high DQE.

Stored data can also be optimised, to give you the most information for analysis.

Longer Acquisition Times

Light-coupled cameras can damage sensitive samples even within a short period of time, which makes them unsuitable for in-situ research.

Counting at low dose is ideal for in these situations, giving you high resolution results. For example, samples such as zeolite (below) can be studied for longer periods – even minutes long. In addition to this, the camera is capable of capturing high speed in-situ events that were previously difficult to capture.
