Applied Photographic Optics: Lenses and Optical Systems for ...
It is, however, possible to obtain a variation in focal length with afocal
attachments which fit in front of the prime lens by conventional screw or bayonet
fittings. An afocal attachment of the telescopic type is given by the separation of a
pair of ...

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 ...
