Transmission Electron Microscope (TEM) > Lenses

Electron lenses are the magnetic equivalent of the glass lenses in an optical microscope and to a large extent, we can draw comparisons between the two. For example the behaviour of all the lenses in a TEM can be approximated to the action of a convex (converging) glass lens on monochromatic light. The lens is basically used to do two things:


In a TEM, can we expect to have 'monochromatic' radiation passing through every lens?
