Stadivari
With the possibility to be set-up vertically as well as horizontally, the STADIVARI increases its scope of application.
The STADIVARI can be used for single crystal and powder diffraction. The Open Eulerian Cradle offers enough space to add high pressure cells, high- or low- temperature devices or other chambers.
In the dual beam setup, all combinations of tubes and microfocus BDS are possible: two sealed tubes, one sealed tube and one microfocus BDS or two microfocus BDS.
As the youngest member of the long line of STOE diffractometers, the STADIVARI is fully integrated in the well-established STOE X-Area software package.

TENGRA
5.3 megapixel bottom-mounted TEM camera
Tengra is EMSIS’ 5.3 Megapixel TEM CCD bottom mounted on axis camera. This state of the art camera offers a great value solution for all standard TEM image acquisition applications with a strong focus on materials sciences. Tengra combines a large, sensitive CCD chip with attractively high readout speed, tapered fiber optics and a perfectly matched phosphor scintillator, to meet the highest quality demands.
The Tengra camera system provides extraordinary resolution with its 2:1 fiber optic taper, which increases the effective pixel size to 18 µm x 18 µm; hence ideally matching scintillator thickness and pixel size and ensuring that the maximum number of photons are detected. This highly efficient conversion of primary electrons in the scintillator combined with optimized electronic design delivers a near perfect signal-to-noise ratio, resulting in an outstanding image with optimal resolution and high sensitivity.
A Peltier cooling, supported by a self contained water cooling system, minimizes the CCD dark current of the Tengra camera system and stabilizes the system temperature. A well capacity of over 60,000 electrons results in an efficient 14-bit dynamic range and a perfect signal—to—noise ratio, ensuring data precision for any imaging task. The interline CCD chip provides up to 2304 x 2304 pixel resolution resulting in a large field of view of 41 mm x 41 mm, which enables the camera to offer a field of view corresponding approximately to half the size of a conventional photo plate.
The Tengra is a high speed digital imaging solution supporting several binning modes as well as partial read out. Using the binning mode increases frame rates and sensitivity. Capturing and streaming digital video directly from live images to observe dynamic events has been a basic element of our imaging platform already for years. The Tengra is an ideal solution for recording high resolution electron diffraction patterns. The high anti blooming performance of the CCD sensor and advanced CCD electronic design make the recording of electron diffraction patterns without artifacts an easy and routine task. It guarantees optimum sensitivity and resolution for diffraction imaging.
QUEMESA
11 megapixel bottom-mounted TEM camera
The Quemesa provides everything expected of a high end TEM CCD camera today: the extremely high resolution, very high sensitivity, superior contrast, high frame rates, and a large field of view. These superior properties make the Quemesa the ideal choice both for biomedical and materials science applications. The most satisfying aspect of this CCD TEM camera is that the TEM itself is now the only limiting factor with regard to resolution and sensitivity for most current TEM applications — no longer the camera.
High sensitivity and contrast at optimal resolution are the requisite ultimate goals for any TEM camera system. Every single photon generated in the scintillator per incident electron is of importance. The camera scintillator needs to be optimized to achieve the maximum signal from the pear shaped interaction volume. This is done by matching the effective pixel size through optimization of scintillator thickness. The Quemesa camera system does this perfectly. Bringing scintillator thickness and pixel size into ideal correlation with one another ensures the maximum number of photons is detected. This guarantees an outstanding image.
The 2:1 fiber optical taper provides the highest quality. This increases the effective pixel size to 18 µm x 18 µm. In combination with the optimized scintillator thickness, this ensures optimal resolution and sensitivity. The taper provides a further benefit — an extremely large field of view for a bottom mounted TEM CCD camera. Its dimensions are almost comparable to the photo plate size of most current TEMs.
The Quemesas 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. Due to highly efficient conversion of primary electrons in the scintillator and optimized electronics design, the Quemesa 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.
