In 1906, Joseph H. Ford put forth an original idea for increasing the magnification power of the microscope. His idea was to use condensed parallel rays of light thereby increasing the illumination of the object. He also proposed to shorten the distance between the lens and the image of the object, resulting in shorter tube length and increased the magnification power. By creating a bending path for the light rays, he was also able to magnify the size of the image formed. This idea became the basis for the formation of all modern microscopes.
