The camera system combines a large, fast sensitive CCD chip with attractively high readout speed, tapered fiber optics fulfilling the most stringent quality demands and a perfectly matched phosphor scintillator. The most satisfying aspect of this new 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.
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.
Olympus Soft Imaging Solutions (formerly Soft Imaging System) has earned a remarkable reputation for their successful TEM camera and software product line-up over the past two decades. Based on our profound technological know-how and, just as important, our application experience, Olympus Soft Imaging Solutions has released innovative and notably successful TEM camera solutions. Now, once again we offer a new camera concept - the Quemesa – setting a new benchmark.
Everything counts – the camera concept
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 superbly. 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. High quality tapered fiber optics are also required. The taper provides a further benefit – an extremely large field of
view for a bottom-mounted TEM CCD camera. Its dimensions are comparable to the photo plate size of most current TEMs.
Because everything counts. And that's what Quemesa stands for – superior technical implementation and optimal user friendliness.
