Zeiss
The Zeiss UEM is a brightfield microscope. The Zeiss UEM uses reflected-light illumination. The Zeiss UEM has binocular viewing at 45°.[1][2][3]

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