Abstract:
There is provided an energy filter capable of being simplified in structure and of achieving low aberrations. The energy filter ( 100 ) includes a first sector magnet ( 10 ) and a second sector magnet ( 20 ). The first and second magnets ( 10, 20 ) are configured mirror-symmetrically with respect to a symmetry plane (M). There are one focal point of crossover in the X direction and one focal point of crossover in the Y direction. The focal point of crossover in the X direction and the focal point of crossover in the Y direction are at an energy dispersive plane (S 2 ). There are two focal points of image in the X direction and two focal points of image in the Y direction. The focal points of image in the X direction and the focal points of image in the Y direction are at the symmetry plane (M) and at an achromatic plane (A 2 ).

Claim (Index 4):
The energy filter as set forth in  claim 1 , wherein\n the sum of the angle of deflection through which said charged particle beam is deflected in said first sector magnet and the angle of deflection through which the beam is deflected in said second sector magnet is 90 degrees, each of the first and second sector magnets has two mutually opposite polepiece surfaces which are parallel to each other, and the distance L between the energy dispersive plane and the achromatic plane satisfies the relation: L>3.2 R, where R is the radius of a central trajectory of the charged particle beam in the second sector magnet.
