The highly sensitive and fast interline CCD chip provides 2304 x 2304 pixel resolution with 14-bit dynamic range, a full well capacity of over 60,000 electrons and antiblooming of at least 100x.
The Tengra supports several binning modes: binning 2, 3, and 4. Using the
binning mode means increasing the frame rates and sensitivity. Binning for
allows acquisition with up to 12 frames per second (depending on exposure
Tengra’s very fast single port read-out supports high frame rates of more than 12 fps, making it much more convenient to scan and focus on the PC monitor. The use of single port readout ensures a homogeneous CCD response over the whole readout area. Even when in the highest quality mode (full resolution) the camera provides more than 2 fps. This camera provides superb dynamic range and sensitivity no matter which resolution mode is employed.
The CCD chip of the Tengra is Peltier-cooled and stabilized at
a temperature of 15°C.
The 2:1 fiber-optical taper provides the highest quality. This increases effective pixel size to 18µm x 18µm. In combination with the optimized scintillator thickness, this ensures optimal resolution and sensitivity.
Due to highly efficient conversion of primary electrons in the scintillator and optimized electronics design, the
Tengra system gains a near perfect signal-to-noise ratio, resulting in very high sensitivity. This enables you to view your samples on your monitor at beam intensities so low it would normally prevent seeing an image on the TEM viewing screen. The finest detail is still shown perfectly in the camera image.
Integration of the Tengra with iTEM, Olympus Soft Imaging Solutions TEM imaging
platform, ensures Real-Time shading correction, intensity histograms, auto contrast adjustment and Real-Time Fast Fourier Transformations during image acquisition.
The Tengra is completely integrated with iTEM, Olympus Soft Imaging Solutions’ TEM imaging platform. This guarantees numerous real-time functions such as real-time shading correction, real-time gray-value histograms, automatic contrast enhancement as well as Fast Fourier Transformation during live image acquisition. Furthermore, iTEM offers functions such as image labeling, image processing, archiving, analysis and report generation. Print-outs in photo quality can be made mere seconds after acquisition.
