1986 B. Paczyński in Astrophysical Jrnl. 301 503/1 If a galaxy is treated as a transparent lens with a smooth density distribution, then it may form a few images of a distant source of radiation... These will be referred to as ‘macroimages’.

1989 Nature 27 Apr. 745/1 These systems are the gravitationally lensed quasars with several macro-images.

1996 Ann. Rev. Astron. & Astrophysics 34 420 The term ‘microlensing’ was proposed by Paczyński..to describe gravitational lensing that can be detected by measuring the intensity variation of a macro-image made of any number of unresolved micro-images.
