Celeritas and Celeritas XS
ULTRA-FAST 4D STEM CAMERAS
Celeritas and Celeritas XS are revolutionary new direct detection cameras for four-dimensional scanning transmission electron microscopy (4D STEM). Based on a next-generation direct detection sensor,
these detectors far exceed the frame rate of other 4D STEM detectors while also delivering at least four times more pixels and exceptional image quality.
POWERFUL IMAGING CAPABILITY
4D STEM is a cutting-edge technique that uses the richness of information available in STEM for exploring the structure of materials. Rather than a single averaged signal,
4D STEM cameras capture the full electron diffraction pattern so that researchers can peer into the subtle details of data, visualizing atoms that are difficult to see in conventional STEM
and extracting information about crystal orientation, strain, electric and magnetic fields, and other important features.
However, until now researchers have had limited choices for 4D STEM detectors. Previous generation 4D STEM detectors took about 15-20 minutes to capture a one-megapixel STEM image, which is far too slow to be practical.
CELERITAS – BUILT FOR SPEED
Celeritas is the Latin word for speed, and we could not think of a better word to describe these cameras.
The base model Celeritas features acquisition speeds of up to 16,000 frames per second, whilst the premium Celeritas XS detector features acquisitions speeds of up to 87,000 frames per second. At almost 100x faster, than earlier 4D STEM detectors,
this enables a one-megapixel 4D STEM virtual image to be captured in about 12 seconds. This introduces a paradigm-shift for 4D STEM, enabling users, for the first time, to capture 4D STEM datasets at comparable speeds to conventional STEM images.
4D STEM experiments that would require hours of data collection with another detector can be performed in minutes using Celeritas or Celeritas XS.
HIGHER DYNAMIC RANGE
A unique high dynamic range (HDR) imaging mode under development offers over 10x higher dynamic range per frame than was achievable in previous monolithic active pixel sensor direct detectors. Fast frame rates and a large number of pixels also facilitate greater dynamic range and enable higher probe currents to be used to acquire data, giving Celeritas and Celeritas XS the flexibility to operate over an extremely wide range of imaging conditions.
ULTRAFAST IN SITU TEM
With one million (1024 x 1024) pixels, Celeritas and Celeritas XS are also excellent high-speed TEM cameras, enabling applications such as ultra-fast, sub-millisecond time-resolution for in situ TEM imaging.
