Microscope

1590

It wasn’t until Zacharias Janssen — a Dutch lensmaker — realised that by inverting the lens structure of early prototype telescopes you could get a high degree of magnification that the microscope was invented in the 16th century. These initial microscopes were simple compound types, combining a magnifying objective lens with an eye lens. Advancements soon followed though and, after Robert Hooke published Micrographia in 1655, the microscope became a staple tool for any scientist.
