Energy filter image generator for electrically charged particles and the use thereof |
摘要 |
The invention relates to an energy filter image generator for filtering electrically charged particles. The inventive energy filter comprises at least two toroidal energy analysers ( 30, 40 ) arranged one inside the other. A transfer lens device ( 20 ) is disposed between the plane of emergence ( 5 ) of the first energy analyser ( 30 ) and the plane of incidence of the second energy analyser ( 40 ), thereby making it possible to obtain the perfect energy filtered reproduction of the surface ( 1 ') of a sample on a detector ( 10 ).
