The AmScope SW24BX binocular stereo microscope head has a pair of 10x20mm widefield high-eyepoint eyepieces, a 2x/4x objective, and a 0.5x Barlow lens. 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 2x/4x objective to provide 10x, 20x, and 40x magnification, and a longer working distance for inspecting large-scale specimens that require handling or repair. The microscope includes a 0.5x Barlow lens that can be added to the objective to decrease the magnification range. A Barlow lens with a magnification of less than 1.0 reduces magnification and increases the working distance. 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.
