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 3):
The energy filter as set forth in  claim 1 , wherein\n the sum of the deflection angle of the charged particle beam in said first sector magnet and the deflection angle of the charged particle beam in said second sector magnet is 180 degrees, each of said first and second sector magnets has two mutually opposite polepiece surfaces which are parallel to each other, and the distance L between said energy dispersive plane and said achromatic plane satisfies the relation: L>3.6 R, where R is the radius of a central trajectory of the charged particle beam in the second sector magnet.
