The low spherical aberration of the objective lens gives a smaller point resolution as well as produces fewer oscillations of the contrast transfer function (CTF) beyond the point resolution. The accurate determination of the spherical aberration coefficient Cs is very important to many applications of EM techniques, such as electron holography [1,2], image processing and deconvolution [3], and electron crystallography of proteins [4].
