Abstract
A mass analyzer comprises a pair of planar electrode structures. The electrode structures are disposed opposite to each other, parallel to each other, and axially offset from each other. The electrode structures are configured to generate, in response to an applied voltage, a cylindrically-symmetric, annular electric field comprising an annular radially focusing central lens region surrounding an axis of symmetry, and an annular mirror region surrounding the annular radially focusing central lens region.
