History of the Microscope
Who Invented the First Microscope?
The history of the microscope spans centuries.
Roman philosophers mentioned “burning glasses” in their writings but the first primitive microscope was not made until the late 1300’s. Two lenses were placed at opposite ends of a tube.
This simple magnifying tube gave birth to the modern microscope.
Grinding glass to use for spectacles and magnifying glasses was commonplace during the 13th century. In the late 16th century several Dutch lens makers designed devices that magnified objects, but in 1609 Galileo Galilei perfected the first device known as a microscope.
Dutch spectacle makers Zaccharias Janssen and Hans Lipperhey are noted as the first men to develop the concept of the compound microscope.
By placing different types and sizes of lenses in opposite ends of tubes, they discovered that small objects were enlarged.
Lens Improvement
Later in the 16th century, Anton van Leeuwenhoek began polishing and grinding lenses when he discovered that certain shaped lenses increased an image’s size.
The glass lenses that he created could enlarge an object many times. The quality of his lenses allowed him, for the first in history, to see the many microscopic animals, bacteria and intricate detail of common objects.
Leeuwenhoek is considered the founder of the study of microscopy and an played a vital role in the development of cell theory.
Achromatic Lens
The microscope was in use for over 100 years before the next major improvement was developed.
Using early microscopes was difficult. Light refracted when passing through the lenses and altered what the image looked like.
When the achromatic lens was developed for use in eyeglasses by Chester Moore Hall in 1729, the quality of microscopes improved.
Using these special lenses, many people would continue to improve the visual acuity of the microscope.
Mechanical Improvements
During the 18th and 19th centuries, many changes occurred in both the housing design and the quality of microscopes.
Microscopes became more stable and smaller. Lens improvements solved many of the optical problems that were common in earlier versions.
The history of the microscope widens and expands from this point with people from around the world working on similar upgrades and lens technology at the same time.
August Kohler is credited with inventing a way to provide uniform microscope illumination that allowed specimens to be photographed.
Ernst Leitz devised a way to allow for different magnifications using one microscope by putting multiple lenses on a movable turret at the end of the lens tube.
Looking for a way to allow more light-spectrum colors to be visible, Ernst Abbe designed a microscope that in a few years would provide Zeiss with the tools to develop the ultraviolet microscope.
