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 ensure 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.
