(Figure 3) Defocus curve. CTF is a refractive lens with smooth transition in focus between two distinct foci in the optical zones, which creates a continuous defocus curve and achieves a sharp image on the retina from infinity to intermediate, and from intermediate to near focus.5 (Image courtesy of Dr Monteiro)
