The personnel of CPO have considerable expertise in designing systems in charged particle optics.

Prof. Frank Read has retired from general consultancy, though he still takes on selected work. He is listed in the consultant network alongside the other specialists - vetted, practising CPO users who help scope a problem, set it up in the software, and support you through it. Every new CPO3D, CPO3DS or Complete licence includes an initial consultation with a specialist of your choosing, which we arrange and pay for. If you would rather we matched you to someone, please get in touch. Frank's consultancy record is set out below.

Prof. Frank Read has acted as a consultant in instrumentation and charged particle optics for many companies, including:

• Kratos Analytical Ltd, Manchester, UK

• Ferranti Ltd, Manchester, UK

• Shimadzu Research Laboratories (Europe) Ltd, Manchester

• VG Scientific Ltd, East Grinstead, UK

• Corning, Inc, New York, USA

• Photek Ltd, St. Leonards-on-Sea, UK
