History of Microscopes

Hans Janssen and Zacharias Janssen are held to be the inventors of the microscope, according to the recorded letters of the Dutch envoy, William Boreel. The invention was colse to the year 1595. Galileo Galilei developed a aggregate microscope using a convex and a concave lens in the year 1609. The formulation of Christian Huygens in the 17th century, the simple 2-lens ocular ideas with achromatic revision is popular even today. Anton van Leeuwenhoek popularized the functionality of the instrument among the biologists and the credibility, the "Father of Microscopy" is ordinarily awarded to him. Leeuwenhoek made his illustrious single lens microscope in the year 1673.

During the beginning years of invention, the microscope was a toy in the rich houses. The first vital discovery using microscopes was about the circulating blood ideas of the human body. It then led to many vital discoveries for mankind. The steps such as the revision of spherical 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 furnish the best image projection. The ideas 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 industrial Uv microscope was presented by Zeiss in 1904. In 1930, Fritz Zernike invented the phase variation 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 other 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 ready from 1983.
