The CETCOR has been designed for the compensation of spherical aberration (Cs) in high-resolution transmission electron microscopes (TEM). The corrector compensates all aberrations up to including 3rd order (A1, B2, A2, C3, S3, A3).
The CETCOR can be used variably with accelerating voltages between 30 kV and 300 kV.
Due to the correction of image aberrations the point resolution can be matched to the information limit of the TEM. In modern field emission TEMs, the use of a corrector can improve the point resolution by a factor of two compared to the uncorrected TEM.
In combination with a monochromized electron gun an information limit of 80 pm (at 200 kV) and 50 pm (at 300 kV) can be reached.
The CETCOR is especially suitable for atomic scale resolution TEM of material science applications in the nano sciences.
