AmScope SM-1B Professional Binocular Stereo Zoom Microscope, WH10x Eyepieces, 7X-45X Magnification, 0.7X-4.5X Zoom Objective, Ambient Lighting, Large Table Pillar Stand

The AmScope SM-1B professional stereo zoom microscope has a pair of 10x super-widefield high eyepoint eyepieces, a 0.7x-4.5x zoom objective, and a pillar stand.The binocular viewing head has an interpupillary range of 55 to 75mm, a 45-degree inclination to reduce eye and neck strain, and 360-degree rotation to enable sharing. The WH10x20mm super-widefield high-eyepoint eyepieces combine with the 0.7x-4.5x zoom objective to provide 7x-45x continuous zoom magnification and a longer working distance for inspecting large-scale specimens that require handling or repair. High-eyepoint objectives ease viewing for users who wear glasses, and dioptric adjustment accommodates individual eye-strength differences. 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. Ambient lighting illuminates the specimen, eliminating the need for power or batteries. The pillar-style stand secures the head for precise focusing. Bilateral coarse focus eases use for left- and right-handed users. The extra-large table stand has a reversible black and white stage plate that provides contrast with light and dark-colored specimens, and stage clips to secure the specimen in place. The stage plate has a 3-3/4" diameter (95mm). The stage is 3/4 x 10 x 12-1/2 inches/20 x 280 x 320mm (H x W x D, where H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back).SpecificationsHeadBinocularMagnification range7x-45x, continuous zoomZoom objective power0.7x-4.5xEyepieces (DIN, 30mm)WH10x20mm high-eyepointZoom range6.5:1Field of view range3/16 to 1-1/4"Optical working distance4"Microscope standPillar standHead movementX-axisIllumination typeN/ALight sourceAmbientPowerN/AMicroscopes 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 used to display an image on a monitor, rather than looking through a lens. Microscopes can have monocular (one), binocular (two), or trinocular (three) eyepieces, with varying magnification abilities. Magnification ability refers to the size of an image. Resolution, also known as resolvant power, refers to the clarity of the image. The interaction between field of view (FOV), numerical aperture (NA), and working distance (WD) determines resolution. Microscopes can control magnification through a fixed focus, or through a range of adjustments. They can also utilize LED, fluorescent, and mirror light sources to help control viewing capabilities. Microscopes are widely used in education, lab research, biology, metallurgy, engineering, chemistry, manufacturing, and in the medical, forensic science, and veterinary industries.United Scope manufactures microscopy equipment and accessories under the brand name AmScope.
