1st invention of Microscope.
Zaccharias Janssen and his son invented the Microscope. -
1st change.
Robert hooke, hooked at a sliver of cork through a microscope lens and noticed some "pores" or "cells" in it. -
2nd change.
Anton van Leeuwenhoek built a simple microscope with only one lens to examine blood, yeast, insects and many other tiny objects. Leeuwenhoek was the first person to describe bacteria, and he invented new methods for grinding and polishing microscope lenses that allowed for curvatures providing magnifications of up to 270 diameters, the best available lenses at that time. -
The second microscope.
Anton van Leeuwenhoek used a simple microscope with only one lens to look at blood, insects and lots of other objects. He was first to describe cells and bacteria, seen through his very small microscopes. -
Getting techincal.
A couple technical changes make microscopes better and easier to use, which makes to microscopy become more popular among scientists. An important discovery is that lenses with two types of glass could reduce the chromatic effect, with its disturbing halos resulting from differences in refraction of light. -
Chromatic effect.
Several weak lenses put together, at certain distances can give good magnification without blurring the image. -
Reflective light.
Inventors and scientists added additional components to the microscope that would incorporate the use of reflective light to help the microscope function at a higher level than ever before. The advances made during the twentieth century are the most recent major technological changes to microscopy as we know it today. -
improvements.
Scientists and researchers kept improving upon the work of previous generations and succeeded in increasing the magnifying power of microscopes. This advancement allowed users to view even smaller objects than ever before in great detail. -
Ultramicroscope.
Richard Zsigmondy developed the ultramicroscope that could study objects below the wavelength of light. -
The electron microscope.
Ernst Ruska developed the electron microscope. The ability to use electrons in microscopy greatly improves the resolution. It allowed people to see the fine details inside and outside of cells, small creatures and many other things. -
First test-tube baby.
