Manufacturer Description

The BestScope BS-3040T Trinocular Stereo Zoom Microscope has a pair of 10x extra-widefield eyepieces, a trinocular port, a 0.8x to 5x zoom objective for 8x to 50x continuous magnification, upper and lower LED illumination, interchangeable stage plates, coaxial focus, and a fixed stage with clips. The trinocular viewing head has a binocular head with a pair of eyepieces with interpupillary adjustment and a fixed inclination to reduce eye and neck strain, and a trinocular port that accepts a camera adapter (sold separately). The zoom 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 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 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. The glass stage plate allows light to pass through from below. 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.

Microscopes 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.

BestScope International Ltd. manufactures microscopes, digital cameras, and accessories for education, inspection, research, and clinical and industrial applications. The company, founded in 1995, is headquartered in Beijing, China.
