Hermann Grimmeiss Hermann Grimmeiss (August 19, 1930), is a German-Swedish physicist. He became the first professor of solid-state physics at Lund University in 1965, and he held his post until his retirement in 1996. He became an important part of the Department of Physics and focused his research on electrical and photoelectric studies of semiconductor defects. He was elected as a member of the Royal Swedish Academy of Engineering Sciences in 1977 and the Royal Swedish Academy of Sciences in 1978.
Magnetic lens A magnetic lens is a device for the focusing or deflection of moving charged particles, such as electrons or ions, by use of the magnetic Lorentz force. Its strength can often be varied by usage of electromagnets. Magnetic lenses are used in diverse applications, from cathode ray tubes over electron microscopy to particle accelerators.
