DDD Camera Systems
- achieve very high sensitivity and resolution by detecting high-energy electrons directly, without a scintillator.
- achieve the highest detective quantum efficiency (DQE) of any EM detector, support very high frame rates to enable single electron counting.
- target segments – best suited to applications requiring the highest efficiency detection such as Cryo-EM of biological materials
Lens-coupled CCD Camera Systems
- use a self-supporting thin film scintillator to convert high-energy electrons into light and a very high optical efficiency de-magnifying lens to relay the light to a CCD, better matching point size in the scintillator to CCD pixel size and also reducing image quality degradation caused by light and electron scattering.
- main features and benefits – more information recorded per image, no distortions or artifacts facilitate tomography and large mosaics, interchangeable scintillators for optimization to energy and imaging need.
- target segments – especially well suited to intermediate and high-voltage EM, tomography and large area image reconstruction requiring excellent dynamic range and freedom from artifacts and distortion.
Bottom-mount fiber optic-coupled CCD Camera Systems
- use a scintillator to convert high-energy electrons into light which is then proximity focused onto a fused fiber optic bundle that carries the light to the surface of the CCD
- main features and benefits – compact, efficient collection of light, large format CCDs with large pixels for good resolution and wide field of view
- target segments – robust reliable performers well suited to multi-user, shared resource environments supporting a diversity of applications including materials science, pathology, and biological research
