## Overview

The Swift Optical SM98-SM90CL is a professional-grade modular stereo microscope featuring 10x widefield eyepieces, 20x/40x magnification via 2x and 4x achromatic objectives, and a 360° rotatable binocular head with ergonomic 45° inclination. It offers versatile upper and lower LED illumination with adjustable intensity, a fixed stage with frosted and reversible plates, and dual rack-and-pinion focusing knobs with slip clutch for precision. Designed for educators, hobbyists, and professionals, it combines durability with advanced optics to deliver clear, color-corrected 3D views of specimens, perfect for detailed inspection and hands-on manipulation.

## Description

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 appliances.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.Microscope Head and Optics SpecificationsHeadBinocularMagnification20x (11.5mm field of view) and 40x (5.75mm field of view)Head inclination45 degreesHead rotation360 degreesInterpupillary adjustment55 to 75mmEyepiecesWidefield 10x 23mmObjectives2x and 4x, parfocal, parcentered, achromatic objectivesMicroscope Illumination and Stage SpecificationsFocus typeDual knobs, mounted on rack-and-pinion mechanism with slip clutch and tension adjustmentWorking distance80mmLight sourceLEDIllumination typeUpper/lower, 3W, upper has adjustable angle, switches and rheostatStage typeFixed, 100mm frosted glass stage plate, 100mm reversible (black/white) plastic stage plate, two stage clipsMicroscope dimensions14-3/4 x 6-3/4 x 9-1/2 inches/375 x 167 x 242mm (H x W x D)Weight8.2lb. (18.1kg)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.
