Abstract:
Provided is a compact device which captures, over a large solid angle range, electrically charged particles emitted from a point source and parallelizes the trajectories of said charged particles. The present invention is configured from: an electrostatic lens comprising a plurality of axisymmetric electrodes ( 10 - 14 ) and an axisymmetric aspherical mesh ( 2 ) which has a surface that is concave away from the point source; and a flat collimator plate ( 3 ) positioned coaxially with the electrostatic lens. The acceptance angle for the electrically charged particles generated from a point source ( 7 ) is ±30° or greater. The shape of the aspherical mesh ( 2 ), and the potentials and the positions of a ground electrode ( 10 ) and application electrodes ( 11 - 15 ) are adjusted so that the trajectories of the electrically charged particles are substantially parallelized by the electrostatic lens. The electrostatic lens and the flat collimator plate are positioned on a common axis.

Claim (Index 5):
An electrostatic lens as set forth in  claim 1 , further comprising:\n a mesh shape of said substantial spheroid being expressed by d mesh  being expressed by a polynomial function as expressed by a mathematical formula below. [ Equation \ue89e \ue89e 1 ] \ue89e d mesh = d 2 + ( d 1 - d 2 ) \ue89e \u2211 i = 1 n \ue89e ( a i / w ) \ue89e \ue89e cos ( i ) \ue89e \u03b1 ( 1 ) ( \u03b1 = \u03c0 2 \ue89e \u03b8 / \u03b8 max , w = a 1 + a 2 + \u2026 + a n ) (In formula (1), d mesh  being a distance from the point source to a mesh surface position, distance d 1  being a distance from a point source to a mesh tip position on an analyzer symmetric axis, d 2  being a distance from a point source to an edge position, an angle \u03b8 and \u03b8max are deviation angles from an analyzer symmetric axis for determining a mesh surface and a mesh position, respectively, \u03b1 being a function of angle \u03b8 and n being a dimensionality and w being determined by a parameter a 1 \u02dca n .
