DE-20 Camera System

DE-Series Cameras


Don’t get left behind as direct electron detection revolutionizes TEM. It’s time to propel your research with a powerful yet easy-to-use direct detector…

Exceptional performance, flexibility, and ease-of-use. The ultimate upgrade for low-dose TEM.

Specifically designed for low-dose applications, the DE-20 features the 9th generation of our revolutionary Direct Detection Device (DDD®) sensor, delivering industry-leading low-noise images, excellent signal-to-noise ratio, and flexible “movie-mode.” The DE-20 has 6.4 μm pixels optimized for excellent resolution (MTF) and very low noise over a broad range of magnifications and exposure rates. It includes an integrated Faraday plate, and it delivers full-frame unbinned streaming at up to 32 frames per second (fps).

On top of its already exceptional performance, for the most demanding applications, an resolution and noise may also be optimized using an optional module enabling single electron counting.

Direct Electron acknowledges the National Institutes of Health (USA) for supporting the development of the DE-series cameras under grants R44GM103417 and R44RR024964.


DE-12 Camera

All of our DE-series cameras deliver state-of-the-art performance and unique features that make them ideal for a wide range of TEM applications.

  • Direct detection of primary electrons—a revolutionary advancement in TEM data quality.
  • High signal-to-noise ratio (SNR) with consistent performance across all spatial frequencies and TEM magnifications.
  • “Movie mode” provides high-speed acquisition of a continuous stream of frames with nearly 100% duty cycle (no dead time between frames).
  • Innovative movie-processing software further enhances data quality through drift correction, per-particle motion correction, radiation damage compensation, post-acquisition exposure setting, etc.
  • High performance for demanding applications, while maintaining ease-of-use and flexibility to maximize data collection efficiency.
  • The ultimate camera for in situ TEM, ETEM, DTEM, and other high-speed applications.
  • Ultra high performance imaging in an elegantly designed, flexible, and easy-to-use camera system.
