a magnifier composed of a single convex lens
Robert Hooke invented the first compound microscope.
There is no apparent connection between van Leeuwenhoek who developed his simple (single lens) microscope system and the work of Zacharias Janssen is associated with the compound (two lens) microscope invented in 1590. Van Leeuwenhoek was unable to use the compound microscope because magnification was too low. The microscopes built by van Leeuwenhoek (around 1670) had ten times the magnification of the compound microscopes of the day. One could say that Janssen helped van Leeuwenhoek succeed by getting everyone else to use the inferior microscope.
