History of Microscopes

Hans Janssen and Zacharias Janssen are held to be the inventors of the microscope, agreeing to the recorded letters of the Dutch envoy, William Boreel. The invention was nearby the year 1595. Galileo Galilei industrialized a combination microscope using a convex and a concave lens in the year 1609. The formulation of Christian Huygens in the 17th century, the uncomplicated 2-lens ocular law with achromatic correction is beloved even today. Anton van Leeuwenhoek popularized the functionality of the instrument among the biologists and the credibility, the "Father of Microscopy" is generally awarded to him. Leeuwenhoek made his preponderant particular lens microscope in the year 1673.

During the beginning years of invention, the microscope was a toy in the rich houses. The first indispensable discovery using microscopes was about the circulating blood law of the human body. It then led to many indispensable discoveries for mankind. The steps such as the correction of rotund aberration, use of achromatic lenses etc were appreciated while the 1820's. August Kohler introduced the microscope lamp with filters in 1880. He also finalized the condenser position to provide the best image projection. The law of the microscope was published by Ernst Abbe in 1873. In the same year, Ernst Leitz introduced the microscope with a revolving mount for 5 objectives. The oil immersion lens was used from the year 1878, and the apochromatic objective was introduced into microscopy by Ernst Abbe in1886.

Microscope

The first commercial Uv microscope was presented by Zeiss in 1904. In 1930, Fritz Zernike invented the phase dissimilarity microscope, which helps to study transparent living things. The revolutionary Tem electron microscope of Ernst Ruska and Max Knoll was introduced in 1931 and the scanning electron microscope was evolved later in 1937. Yet someone else milestone in the history of microscopes is the scanning tunneling microscope invented in 1981 by Gerd Binnig and Heinrich Rohrer, which help to visualize the atomic level 3D structure of objects. The scanning laser confocal microscope was commercially available from 1983.
