A Study on Scaling Symmetrical Condenser-Objective Lenses
A.S.A. Alamir Physics Department, Faculty of science, Assuit University, Assuit, Egypt
(Received 12 September 1994, accepted 2 February 1995)
Abstract
Scaling down the dimensions of a conventional magnetic objective lens to reduce aberrations is studied in detail. The value
of other aberration coefficients for optimum lens size corresponding to desired minimum aberration are estimated.

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link containsarticle metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means:
- if your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages,
- you can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library,
- you can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
