    Abstract: A Wien filter to be disposed inside a lens barrel made of a magnetic material includes: a plurality of electromagnetic poles disposed at equal angular intervals about a center axis of the lens barrel; a first magnetic shield disposed so as to cover the area around the plurality of electromagnetic poles; and a second magnetic shield disposed so as to cover the area around the first magnetic shield. The first magnetic shield is supported by a first support member made of a non-magnetic material provided at an inner surface of the second magnetic shield. The second magnetic shield is supported by a second support member made of a magnetic material provided at an inner surface of the lens barrel.

    Abstract: The present invention advantageously provides an ion milling device that can set a high-precision processing area with a simple structure. The ion milling device includes a sample holder that holds a sample and a mask partially restricting irradiation of the sample with an ion beam. The sample holder includes a first contact surface that contacts an end surface of the sample located on a passing orbit side of the ion beam, and a second contact surface that contacts an end surface of the mask so that the mask is located at a position spaced apart from the ion beam more than the first contact surface.
