Aspex

The origins of Aspex Corporation date back to 1992 (formally a division of RJ Lee Group, Inc.) where developers recognized the limitations and costs associated with traditional scanning electron microscopy (SEM). As a result, the company developed and introduced the world's first "personalized" SEM, or PSEM. The timing of the introduction coincided with a number of important trends, including increased emphasis on materials characterization, the outsourcing of R&D applications to service laboratories, and the "quality revolution" of the 1990s. Since then, Aspex has continued to develop various industrialized SEMs for quality and process control purposes.

As of January 9, 2012, FEI Company purchased Aspex from its privately held venture capitalists. After one year of operating under the name "ASPEX, an FEI Company", in 2013 the stand-alone entity of ASPEX was absorbed by FEI and the electron microscopes produced in the Delmont, Pennsylvania facility are now grouped with the FEI offerings.

Although Aspex is not operating as a stand-alone business entity, the three product lines (Express, Explorer and, Extreme) are still available for purchase with their automated software. This enables the user to engage the SEM (with EDX, if equipped) to automatically scan an area of interest about a sample and collect particulate information. Such information includes: morphology, thumbnail image, chemistry (if EDX is equipped)
