Manufacturer Description

The Ken-A-Vision VisionScope 2 binocular stereo microscope with battery pack has widefield 20x 36mm eyepieces, a fixed 45-degree angle viewing inclination, 1x and 3x objectives with 20x and 60x total optical magnification, upper and lower LED lighting, a fixed stage with clips, coarse and fine focusing knobs on rack-and-pinion mount, a frosted 6cm glass stage plate, and a reversible (black/white) 6cm stage plate. The binocular viewing head is interchangeable (additional heads sold separately) and has a pair of eyepieces, fixed inclination to reduce eye and neck strain, eye shields to block ambient light, and rotation capability to provide a more comprehensive view and enable sharing. Dioptric adjustment of 0.20x in the left eyepiece accommodates individual eye-strength differences. The objectives are mounted on a turret to ease magnification changes. The 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. All lenses are coated for use in humidity and inclement weather. 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 LED light source provides bright, cool light for working with temperature-sensitive or live specimens. The light sources are controlled by switches and rheostats. The frosted glass stage plate allows light to pass through from below. The reversible black and white stage plate is used with top-mounted (episcopic) lighting to provide contrast with light- and dark-colored specimens. The fixed stage has stage clips to secure the slide or specimen in place while viewing. Coarse and fine focus knobs on a rack-and-pinion mount speed focusing. A stereo microscope, sometimes called an inspection or dissection microscope, has a longer working distance that enables users to manipulate the object being inspected, and is used in semiconductor and electronics industries or by mineralogists, dentists, and students when the user needs to handle or perform work under magnification, including circuit boards, rocks and gems, and dental appliances.The microscope stand is constructed of cast metal for durability. It has a carry handle for transportation and the base is outlined with polymer to protect the microscope and the table surface. The microscope is approximately 15.75 x 8.5 x 10 inches/40 x 21.6 x 25.4cm (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). The microscope comes with a dust cover, eyepiece guards, objective cover, power supply with multiple plug adaptors, and battery pack for cordless use.Microscope Head and Optics SpecificationsHeadBinocularMagnification20x and 60xHead inclination45 degreesEyepiecesWidefield 20x 36mm, coatedObjectives1x and 3xMicroscope Illumination and Stage SpecificationsFocus typeCoarse and fine, rack-and-pinion mountWorking distance100mmLight sourceLED with switches and rheostatsIllumination typeUpper/lowerStage typeFixed, two stage clips, frosted 6cm glass stage plate, reversible (black/white) 6cm stage plateMicroscope dimensions15.75 x 8.5 x 10 inches/40 x 21.6 x 25.4cm (H x W x D)Power120-240V, + or - 500mA, detachableandRechargeable NiMH battery packWeight6.5lb./2.95kgStandardsISO:9001-2000; MiL Std 105e, CSA, RoHS CP, and CE markingMicroscopes 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.Ken-A-Vision manufactures educational products such as microscopes, cameras, and software.
