A DDD camera with 6.5um pixels and 4K x 4K resolution, suitable for the most extensive applications.

The DE-16 is equipped with the 10th generation of innovative DDD sensors, achieving industry-leading resolution and flexible, seamless display in a 4k x 4k field of view. The DE-16 features 6.5μm pixels optimized for excellent resolution (MTF) across a wide range of magnifications and exposure rates. It is our most versatile direct detection TEM camera, characterized by continuous streaming at up to 60 frames per second, enabling TEM experiments that were previously impossible with direct detectors. This flexibility and cutting-edge sensor technology provide industry-leading resolution for use in materials science or biology applications such as insitu, 4D STEM, electron diffraction, holography, DTEM, and EELS. The DE-16 offers speeds unmatched by other cameras in narrow areas and can be used for numerous applications on the same equipment. In addition to the integrated Faraday plate, users can access full-frame streaming at up to 92 frames per second or select smaller areas to read at significantly higher frame rates (128 x 128 @ 4,237 fps).

Detailed information

[Modulation Transfer Function] The Modulation Transfer Function (MTF) is one of the most widely used scientific methods for describing optical performance. MTF measures contrast across all spatial frequencies. The DDD camera from Direct Electron has very high resolution and contrast, remaining close to the theoretical maximum value even as spatial frequency increases.
【Detective Quantum Efficiency (DQE)】 In the case of TEM cameras, DQE measures the combined effect of the detector's signal performance and noise performance. The DQE curve can be considered with resolution on the X-axis and relative signal-to-noise ratio on the Y-axis, where higher results are better. The DE series demonstrates low noise and high resolution that are theoretically close to the maximum value in both counting mode and integration mode as the spatial frequency increases.
【Carbon Film Thon Ring】 The exceptional high-resolution performance of the DE series cameras from Direct Electron means that the camera is no longer a major limiting factor for TEM resolution. The DE-20 demonstrates very high-resolution bright field TEM imaging, and the Thon ring reaches a resolution of 2.3 angstroms (92% Nyquist).
