DE-12 Camera System

DE-Series Cameras


Time to throw off the limits of traditional CCD cameras and start collecting continuous streams of incredible TEM images…

High-performance with fast and flexible frame rates, at an economical price.

As the very first commercially-available direct detection camera, the DE-12 (4k × 3k pixels) has a long history of reliability and productivity. The current updated DE-12 features the 8th generation of our revolutionary Direct Detection Device (DDD®) sensor, delivering industry-leading resolution and flexible “movie-mode.” The DE-12 has 6.0 μm pixels optimized for excellent resolution (MTF) 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 40 frames per second (fps). Many users choose to acquire data at 75 fps with full-frame readout and 2×-binning, and substantially faster frame rates can be achieved by reducing the readout array size.

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.
