The Jenco International ST-F801 Binocular Stereo Microscope has a pair of 10x eyepieces, 10x and 20x magnification, selectable upper halogen and lower fluorescent illumination, coaxial focus, and a fixed stage with clips. The binocular head has fixed inclination to reduce eye and neck strain. Parfocal objectives ensure that the image stays focused when the magnification is changed. 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 upper halogen light source provides bright light in a concentrated path. The lower fluorescent light source provides cool, white light for observing specimens as they would appear in their natural environment. Lighting can be configured for upper, lower, or simultaneous upper and lower illumination. 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.Jenco International, Inc. designs, assembles, and services microscopes, digital cameras, and accessories for education, inspection, research, and clinical and industrial applications. The company, founded in 2004, is headquartered in Milwaukie, OR.What's in the Box?Jenco International ST-F801 Binocular Stereo Microscope(2) 10x eyepieces
