Worldwide Factory Service


Our factory repair technicians have over 150 years of combined experience working on PHI systems, providing a level of service and knowledge second to none. PHI offers two primary options for resolving system electronics or “optics” issues. Optics consists of any equipment installed in the vacuum chamber, or used to pump the chamber. Depending on your situation, PHI can repair or rebuild your equipment.

Electronic repairs routinely include any hardware or firmware updates, calibration, and complete testing. Optics work includes total cleaning, updates, alignments, out-gassing, and in vacuum testing to ensure operation within specifications

PHI houses a very large inventory of exchange and replacement electronics core boards and components. We also have a good inventory of optics, specific electron and ion gun sources, x-ray sources, specimen stages, and Auger upper nipples. All these items have been thoroughly rebuilt, updated, and tested. This inventory of parts is available for immediate shipment should your situation demand urgent attention.
