What it is

The Zeiss UEM is a metrology and inspection microscope.[3][2]

The Zeiss UEM is a brightfield microscope with reflected-light illumination, binocular viewing at forty-five degrees, and a coaxial X-Y stage.[3][2][1]

How it works

General reference — not yet source-verified

A microscope of this class forms an enlarged optical view of a specimen so an operator can inspect surface features and measure visible structures.

A reflected-light brightfield microscope directs illumination onto the specimen from above and collects the returned light through the imaging optics.

Where it fits in the process flow

General reference — not yet source-verified

A metrology and inspection microscope sits in the measurement and review part of a fabrication or laboratory workflow.

The Zeiss UEM is used after process steps that leave visible surface or structural features that an operator needs to examine before release or further work.

Applications

General reference — not yet source-verified

A microscope of this class is used for surface inspection, feature review, and general optical examination of prepared samples.
