We are delighted to announce that the 32-bit version of CPO software is now available for free. This version is perfect for students and those who wish to explore the software's functionality before purchasing the more powerful 64-bit version.
The free version is built from the same code base as the 64-bit version and can be installed without a license key or internet connection.
Please note that the free version does not include the following advanced features. If you need these options, you can download a 15-day evaluation of the 64-bit version before deciding whether to purchase the full 64-bit edition of the CPO software:

The Boundary Element Method, BEM, deals with surface charges and has many advantages over the methods used in almost all other commercial programs. The programs were developed by Profs Frank Read and Nick Bowring, in the group at Manchester University which was the first to use the BEM in electron optics and which produced the definitive book Electrostatic Lenses, by Harting and Read. Frank has been joined by Ryan O'Neill, working on the further development of the software.
The programs have been described as the gold standard of charged particle optics. The CPO programs are exceptionally accurate and have many advanced options that are not present in other programs.
