Microscope

The origin of microscope can be traced to the ancient world. This was by the evidence of magnifying lenses found in ancient Iraq.

It is also the evidence that craftsmen in Rome used magnifying glass for their fine arts work.

In the first century A.D Seneca described actual magnification by a globe of water. He wrote that letters could be enlarged and made clear by viewing though a globe of glass filled with water.

A thousand years later the Arabian scholar Alhazan wrote a major work on optical principles and described the anatomy of the eye and how the lens focuses images.

The Dutch draper or linen merchant and option Anton van Leeuwenhock (1632 – 1723) ground a single lens with a magnification of about t 500 power in the 1670s.

Leeuwenhock was the first to discover microscopic. His magnifying lenses were small in diameter and had to be held extremely close to the eye and to the specimen.

Robert Hooke (1635 – 1703) made improvements by the 1660s to the device, with which he discovered the cellular structure of plants.

In the 20th century. The electron microscope represented a break through to much higher magnification.
