Abstract: PURPOSE:To obtain a device providing non-astigmatic image formation by specifying the curvatures of electric field and magnetic field distribution curves and the filter length in a Wien filter combined with a pair of inclined magnetic pole pieces and parallel flat plate electrodes. CONSTITUTION:In a Wien filter combined with inclined magnetic poles 11 and 12 and parallel flat plate electrodes 13 and 14, the relationship between Re and Rm providing non-astigmatic image formation using L as a parameter is determined, where Re is the radius of curvature of the electric field, Rm is the radius of curvature of the magnetic field, and L is the filter length. Non- astigmatic image formation is provided within the range of 30mm<=L<=80mm for the optional combination within ranges of Re>=50mm, 12mm<=Rm<=30mm. When the R of the magnetic pole is determined using the inclined magnetic poles 11 and 12, Rm becomes nearly equal to R, thus non-astigmatic conditions can be found by properly selecting Re and L.
