Stereo microscopes are optical inspection instruments that present a three dimensional view of a sample at low to moderate magnification. Stereo microscopes are used for direct visual examination of surfaces, features, and handling tasks where depth perception is useful. In microfabrication environments, stereo microscopes commonly support bench inspection, sample review, and operator setup work around process tools.

A stereo microscope forms separate optical paths for each eye so the user can perceive depth while viewing the specimen. A stereo microscope changes viewing scale through a zoom mechanism while maintaining a broad field suited to manual inspection and manipulation. A stereo microscope is typically used with reflected illumination from above for opaque samples, and some configurations can also be paired with transmitted illumination for transparent specimens.

In semiconductor and microdevice work, stereo microscopes are commonly used outside primary patterning and measurement tools as support instruments for routine visual checks. Stereo microscopes fit around incoming sample review, post process inspection, dicing and packaging preparation, and general handling steps where rapid operator observation is needed. Stereo microscopes complement higher magnification inspection microscopes by covering larger features and providing a more natural view during manual tasks.

Stereo microscopes are used to inspect surface condition, contamination, edge quality, alignment marks, bond areas, and mechanical features on small parts and substrates. Stereo microscopes are also used during sample preparation, probe setup, die handling, and packaging related bench work where depth perception helps the operator. In mixed laboratory environments, stereo microscopes support visual review of fabricated devices, masks, tools, fixtures, and assembled components.
