The compound microscope was developed by Zacharias Janssen around the late 16th century. By placing multiple lenses in a tube, Janssen was able to magnify objects using a combination of lenses, allowing for greater magnification and improved clarity in viewing specimens. This innovation revolutionized the field of microscopy and paved the way for more advanced scientific discoveries.
Hans and Zacharias Janssen invented the first compound microscope in 1590 by placing two lenses in a tube.
It is thought that Zacharias Jansen's father, Hans, helped him build the first microscope in 1595
The first plastic spectacle lenses were developed by Columbia Resins in the 1940s, made from a plastic called CR-39.
