Afocal system (Physics Dictionary)

Afocal system: An optical system that produces no net convergence or divergence of the beam, i.e. has an infinite effective focal length.[7] This type of system can be created with a pair of optical elements where the distance between the elements is equal to the sum of each element’s focal length ( d = f 1 + f 2 {\displaystyle d=f_{1}+f_{2}} ).
