專利摘要(中)
A combined round-multipole magnetic lens comprises a coil bracket, a first pole piece and a second pole piece. At least a first pole shoe of the first pole piece on the coil support and at least a second pole shoe of the second pole piece under the coil support respectively extend towards the central axis. The first pole shoe and the second pole shoe are symmetric according to the central axis, or the first pole shoes and the second pole shoes are respectively symmetrically arranged, and the angle difference between the first pole shoe and the adjacent second pole shoes is 360/2N degrees. A magnetic circuit gap is formed between the first pole shoe and the adjacent second pole shoe, for generating a magnetic field distribution of multi-poles and reducing the volume and the number of power supplies.
