(C) R G Bingham 2005. All rights reserved.. Six pages on recognising some Seidel aberrations. (C) R G Bingham 2005. All rights reserved.. Why recognise Seidel aberrations?. Even in an imaging system that is very complex in design, total aberrations are not zero. Seidel terms will be included at some level, balancing higher-order aberrations. We can look for all such effects in order to see whether the design process was used, or is being used, to best advantage, as discussed elsewhere in this9443
