Stereo microscopes, also known as stereoscopic microscopes, are amazing tools for viewing extremely small objects that are perceptible (but just barely) by the unaided human eye.Many of these “low power” microscopes have the able to zoom to adjustable magnification levels. Stereo zoom microscopes can magnify circuits, computer motherboards, insects, organic specimens (plants, fruits, flowers, etc.), plus many other tiny objects that operators need to examine in greater detail. By exploiting our stereoscopic vision, and utilizing distinct optical paths for each sperate eye-piece, stereo microscopes give operators a more natural (for Homo sapiens, at least) 3D viewing experience. The zooming capabilities of a stereo zoom microscope provide people working in variety of professions more freedom to view specimens (from ants to computer chips) from different angles, and in a range of adjustable magnification levels.
