Description
The 3B Scientific W30665-115 Binocular Stereo Microscope has a pair of 10x widefield eyepieces, a 2x objective, upper and lower LED illumination, a reversible stage plate, coaxial focus, and a fixed stage with clips. The binocular head has a pair of eyepieces with interpupillary adjustment and a fixed inclination to reduce eye and neck strain. Dioptric adjustment accommodates individual eye-strength differences. The objective provides 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. A quick-change fitting eases replacement of the objective. 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 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 sources provide bright, cool light for working with temperature-sensitive or live specimens, and operate on AC power or on a rechargeable battery. A toggle switch offers three different lighting configurations (upper, lower, and simultaneous upper and lower). The reversible black and white stage plate is used with top-mounted lighting to provide contrast with light- and dark-colored specimens. Coaxial focus eases focusing for left- and right-handed viewers. The fixed stage has stage clips to secure the slide or specimen in place while viewing.

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. 3B Scientific manufactures anatomical models, simulators, charts, and other training materials for use in scientific, medical, and patient education. The company, founded in 1948 and headquartered in Hamburg, Germany, meets International Organization of Standardization (ISO) standard 9001: 2008.
