Product Description

Stereo microscope for use in classroom, home school, or hobbyist settings

Binocular head with pair of widefield 10x 23mm eyepieces with 55 to 75mm inter-pupillary adjustment, fixed 45-degree vertical inclination to reduce eye and neck strain, and 360-degree rotation capability to provide a more comprehensive view and enable sharing

2x and 4x parfocal, parcentered, achromatic objectives on a rotating turret for 20x and 40x optical magnification, and low magnification and longer focal length for inspecting large-scale specimens

Variable upper and lower LED lighting with two switches for three light configurations; upper light has adjustable angle

Fixed stage, dual focusing knobs on rack-and-pinion mount with slip clutch and tension adjustment, frosted 100mm glass stage plate with clips for holding samples, reversible (black/white) 100mm plastic stage plate, and blue filter for transmitted light

The Swift Optical SM98-SM90CL Advanced Modular binocular stereo microscope has 10x widefield 23mm eyepieces, a fixed
45-degree angle viewing inclination, 55 to 75mm inter-pupillary adjustment, 360-degree rotation, 2x/4x objectives for
20x/40x total optical magnification, upper/lower LED lighting, a fixed stage with dual focusing knobs, a frosted 100mm
glass plate with clips, and a reversible (black/white) 100mm stage plate. The binocular viewing head has eyepieces with
inter-pupillary adjustment, rubber eyepiece shields to block ambient light, fixed inclination to reduce eye and neck
strain, and 360-degree rotation capability to provide a more comprehensive view and enable sharing. The objectives are
mounted on a turret to ease magnification changes. Parcentered and parfocal objectives ensure that the image stays
centered and focused when the magnification is changed. Achromatic objectives provide color correction of magnified
images. 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. 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 lights are controlled by two switches that offer three different
configurations (upper, lower, and simultaneous upper and lower) and the intensity of the upper and lower lights is
controlled by a rheostat. The frosted glass stage plate allows light to pass through from below and has a blue filter
for increased resolution. 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. Dual knobs on a rack-and-pinion mount with a slip clutch and tension control provide precise
focus. A C-wrench tool (included) enables adjustment of focus control. 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

The microscope frame is constructed of cast metal and has an enamel finish for durability. It has a cord hanger for
storage. The microscope is 14-3/4 x 6-3/4 x 9-1/2 inches/375 x 167 x 242mm (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). A USB port can be used to add-on accessories such as USB lighting. It comes
with a vinyl dust cover and molded polystyrene foam container.

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.

Swift Optical Instruments manufactures microscopes and weather instruments. The company, founded in 1959, is
