Basic Electro-optics for Electrical Engineers
Afocal telescopes are two-lens systems intended to be used with the object at
infinity. The two lenses are separated by the sum of their focal lengths. The
combination focal length is indeterminate using Eq. (1.13), which is interpreted to
mean ...

Optical Imaging and Aberrations: Ray geometrical optics
Besides its use as a telescope or a beam expander, an afocal system can also be
used to change the effective focal length and field of view (which is defined in
Section 2.2.7) of another system by inserting it in the collimated region of the
other ...
