• Galileo Galilei

• Anton Van Leeuwenhoek

This was designed and built by Ernst Ruska and Max Knoll from the ideas of Leo Szilard. This microscope used electrons instead of light.

• Scanning Electron Microscope

• The Transmission Electron Microscope

• Phase Contrast Microscope

He did not realize at the time was that he had just discovered plant cells using his single lens microscope that was illuminated by a candle.

• Anton Van Leeuwenhoek

• Robert Hooke

• Galileo Galilei

• Joseph Jackson Lister

This technology was developed by Godfrey Hounsfield and Allan Cormack and involves the combination of many X-ray images (with the help of a computer) for the purposes of generating cross-sectional views and 3D images.

• Electron backscatter patterns observed

• Confocal laser scanning microscope

• First CAT scanner

The first people who were investigating and developing glasses to make the image large enough to get a better view.

• Asian and Americans

• Romans and Egyptians

• Europeans and Indians

When was the confocal laser scanning microscope developed?

• 13th Century

It is the bouncing back of light when it strikes a smooth surface.
