Stereo microscope used for component inspection, assembly work, and quality control in manufacturing. Enables three-dimensional observation for electronic component mounting inspection, mechanical part surface inspection, welding quality verification, and foreign matter contamination inspection. Primarily binocular type, specialized for low magnification observation from 10x to 100x. Features LED lighting, digital camera compatibility, and movable arm types to meet workplace needs. Unlike metallurgical or measuring microscopes, characterized by direct field observation capability without sample preparation.
