Accu-Scope 3075-LED-E Binocular Zoom Stereo Microscope on E-LED Stand, 10x Eyepieces, 6.7x-45x Magnification, 0.67x-4.5x Objective, Upper/Lower LED Illumination, 100V-240V

The Accu-Scope 3075-LED-E binocular zoom stereo microscope has 10x 20mm widefield eyepieces, 0.67x to 4.5 zoom objective for a zoom range of 6.7x to 45x, Greenough optical system, upper and lower LED transmitted and incident lighting, and a fixed stage, with knobs for zoom and coarse focusing. The binocular viewing head has a pair of eyepieces, fixed inclination to reduce eye and neck strain, and rotation capability to provide a more comprehensive view and enable sharing. Dioptric adjustment accommodates individual eye-strength differences. The zoom objectives provide low magnification and a longer focal length for inspecting large-scale specimens, or specimens that require hands-on manipulation or repair, including rocks, minerals, watches, or circuit boards. The Greenough optical system provides precision image creation. The microscope has 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. The intensity of the lower light source can be controlled using a rheostat. The fixed stage has a frosted glass stage plate in the base for evenly diffused illumination and a reversible black and white stage plate for contrast. Separate knobs for coarse and fine focus speed focusing. A stereo zoom microscope is used for inspection and dissection of specimens when three-dimensional images are desired, and provides zoom, sometimes called pancratic, magnification that allows the user to zoom in on the specimen within a continuous magnification range.The stand is constructed of cast alloy aluminum for durability. The microscope is 21 x 12 x 15 inches (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; and D is depth, the horizontal distance from front to back). Itl has a universal power supply compatible with 100 to 240V. This microscope comes with two stage plates, eye guards, and a dust cover.Microscope Head and Optics SpecificationsHeadBinocularMagnification range6.7x-45xHead inclination45 degreesHead rotation360 degreesInterpupillary adjustment54 to 76mmEyepieces (22mm)Widefield 10x, dioptric adjustment on both eyepiecesObjective0.67x- 4.5 zoom lens objectiveMicroscope Illumination and Stage SpecificationsFocus typeCoarse and zoomWorking distance100mmLight sourceLEDIllumination typeUpper/lowerStage typeFixedMicroscope dimensions21 x 12 x 15 inches (H x W x D)PowerUniversal power supply, 100-240VMicroscopes 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.Accu-Scope, Inc. manufactures microscopes and accessories for education, research, and clinical and industrial applications.
