Great effort has been invested into upgrading the image resolution in SEM up to some 1 nm at 15 keV. However, uncertainty still exists as regards proper appearance of even standard testing specimens. The same energy, current and impact angle of the primary beam and the same type of the secondary electron (SE) detector do not secure identical image contrast. Many details regarding generation, collection and detection of the signal species are important and a quantitative method of the detector assessment is needed. Magnetic and electrostatic fields in the specimen vicinity surely influence the SE trajectories toward detector and these fields vary with the working distance, with arrangement of grounded metallic parts in the specimen chamber, etc. The recently opened systematic study of this problem was started by examination of the collection efficiency.
