MICROSCOPE’S “EYE”
♦ BIG INCREASE IN STRENGTH. Research workers at London’s Imperial College of Science and Technology have succeeded in making the microscope’s “eye” 500 times more powerful. The workers at the college knew that if the wavelength of light were shorter they could study much smaller objects under the microscope. As they could not alter the wavelength of light they had to seek for another medium. They found it in the “electron gun,” which discharges cathode rays having a wavelength 50,000 times shorter. Then came a second problem. When an object is enlarged (as through a microscope or a magic-lan-tern) this is done by bending the light lenses. How could this be done with the stream of electron particles? The rays were deflected to produce the enlargement by passing them through a magnetic field.
