Which aberration a ects a particular experiment is not always as obvious as one would like. Take for example, the simple goal to concentrate the maximum amount of optical power at a certain point using ... WebAny real lens is a thick lens, meaning that it has a non-zero lens thickness t, which is the axial separation between the vertexes of the two refracting surfaces.Lens thickness is a nondirectional distance (therefore, is always positive), measured at the center of the lens along the optical axis (i.e., the lens is not tilted), regardless of the shape or power of the … chahfe fayez
