The article examines a reflecting lens of a planar ion mirror, formed by a channel, adjoining by normal upon the closing lid of the mirror. The wide flange of the channel and the mirror lid have different potentials, are plane-parallel and are on a small distance between each other. A precise analytical expression for the calculation of the field of the reflecting lens has been found using the method of conformal mapping. It is demonstrated that in the ion mirror with the proposed reflecting lens it is possible to adjust the pre-calculated field distribution to approach the theoretically ideal space-time focusing in a wide range of ion energies.
