Amos has been obsessed with even these simplest of microscopes ever since he got one for a birthday as a kid. His intrigue in microscopic worlds became insatiable as he explored anything he could find, from the force within tiny, popping bubbles to the way pieces of copper molded under the poke of a needle.
This type of curiosity in the going-ons of tiny worlds propelled microscopy from its inception. A Dutch father-son team named Hans and Zacharias Janssen invented the first so-called compound microscope in the late 16th century when they discovered that, if they put a lens at the top and bottom of a tube and looked through it, objects on the other end became magnified.
The device laid critical groundwork for future breakthroughs, but only magnified by between 3x and 9x. The quality of the image was mediocre at best, says Steven Ruzin , a microscopist and curator of the Golub Microscope Collection at the University of California at Berkeley.
As a result, no significant scientific breakthroughs came from them for about years, says Ruzin. But by the late s, improvements to the lenses increased the quality of the image and the magnifying power to up to x, paving the way for major discoveries. In , English natural scientist Robert Hooke famously published his book Micrographia with intricate drawings of hundreds of specimens he observed, including distinct sections within the branch of a herbaceous plant.
He called the sections cells because they reminded him of cells in a monastery—and thus became the father of cellular biology. Bradbury, Savile, and Brian Bracegirdle.

Photo by: Vasiliy Koval. History of the Light Microscope Light microscopes date at least to , when Zacharias Jansen — of Holland invented a compound light microscope, one that used two lenses, with the second lens further magnifying the image produced by the first.
Tissue Preparation The advancement of light microscopy also required methods for preserving plant and animal tissues and making their cellular details more visible, methods collectively called histotechnique from histo, meaning "tissue". Varieties of Light Microscopes Most compound microscopes today have an illuminator built into the base.
Kenneth S. Saladin and Sara E. In , Marvin Minsky applied for the first patent for confocal microscopy. At first, this was largely ignored by the scientific community. After the method had been improved with laser technology, however, it was finally generally accepted and became a very popular technique.
The last groundbreaking advance in light microscopy to date was introduced in the s by Stefan Hell , who developed super-resolution fluorescence techniques. This finally enabled the limit of resolving power described by Abbe to be circumvented. Owing to this Stefan Hell was awarded the Nobel Prize in Chemistry together with Eric Betzig and William Moerner for the development of super-resolved fluorescence microscopy. Talk to our experts.
