Performance of thin foil scintillating screen for transmission electron microscopy

Characterisation of the signal and noise transfer of CCD cameras for electron detection

“…We note that for unsupported thin scintillators, the MTF would actually improve for increasing electron energies due to the intrinsically narrower spread of electron trajectories within the scintillator at higher voltage (Fan et al, 1994).…”

Digital imaging in transmission electron microscopy

“…As the added noise contains all Fourier frequencies, including high spatial frequencies, this method tends to give an over‐optimistic estimate of the MTF. The simulations by Meyer & Kirkland (1998) indicate that the discrepancy is smaller for scintillator screens that do not have a support substrate, such as a thin‐foil screen (Fan et al ., 1994).…”

Analysis of the Performance of an 8k x 8k Lens Coupled Detector for Wide-field, High-resolution Transmission Electron Microscopy (TEM)

“…Moreover, lens coupled systems using demagnification lend themselves well to matching the electron footprint of the scintillator to the pixel pitch of the CCD camera. For high-energy electrons at 300keV and above, it starts to become important to move away from fiber optical relays which produce backscattering into the scintillator causing a large plume of light at the scintillator, thereby, degrading resolution (Fan et al 2000, Fan and Ellisman, 1996, Fan et al, 1994. Moreover, it is very difficult to produce a seamless mosaiced imaging system using fiber coupling of the scintillator to the butted CCD detectors.…”
