The AmScope SW2B24 binocular stereo microscope head has a 2x/4x 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 2x/4x objective to provide 20x and 40x 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.
The microscope has rheostat-controlled upper (episcopic) illumination that reflects light off the specimen for enhanced visibility of opaque specimens, and lower (diascopic) illumination that transmits light up through the specimen for enhanced visibility of translucent and transparent objects. A rheostat controls light intensity. A frosted stage plate allows light to pass through from below with transparent specimens, a reversible black and white stage plate provides contrast with light- and dark-colored specimens, and stage clips secure the specimen during viewing. The 15W halogen light source provides bright light in a concentrated path. The pillar-style stand has bilateral coarse focus to ease use for left- and right-handed users. All metal construction is durable and the enamel finish is stain-resistant.
