The AmScope SW13B binocular stereo microscope head has a 1x/3x objective and a pair of 10x20mm widefield high-eyepoint eyepieces. The microscope head has a 3" O-ring style mounting ring. The binocular viewing head has an interpupillary range of 47 to 75mm, a 45-degree inclination to reduce eye and neck strain, and 360-degree rotation to enable sharing. The WF10x20mm super-widefield high-eyepoint eyepieces combine with the 1x/3x objective to provide 10x and 30x magnification, and a longer working distance for inspecting large-scale specimens that require handling or repair. High-eyepoint eyepieces ease viewing for users who wear glasses, dioptric adjustment accommodates individual eye-strength differences, and eye guards ensure comfortable viewing. The optical glass lenses provide sharp images, and are fully-coated to ensure high-resolution images. A stereo microscope, sometimes called an inspection or dissection microscope, has low magnification and a long working distance that enables users to manipulate the object being inspected.

Microscopes are instruments used to enhance the resolution of an object or image. Types include compound, stereo, or digital. Compound microscopes use a compound optical system with an objective lens and an eyepiece. Stereo microscopes show object depth in a three-dimensional image. Digital microscopes are
