Resumen:
We study the formation of caustic surfaces produced by cemented doublet
lenses, considering a plane wavefront propagating parallel to the
optical axis and neglecting the refractive index of the optical cement
between two simple lenses which are in contact. We have already seen
that the shape of caustic surfaces can represent the monochromatic
aberrations that we call image errors; furthermore the shape of the
caustic can be modified by changing the parameters of design for two
conic lenses in contact, in such a way that if we are able to vanish the
caustic, the optical system produces either an image without spherical
aberration or longitudinal chromatic aberration reduced, commonly known
as spherochromatism. The shape of the caustic surface is a function of
the indices of refraction involved in the process of refraction, and all
the parameters of two simple lenses. We provide an analytic equation for
the caustic surfaces in a meridional plane and an example is presented.
