## Overview

The AmScope SM-4BY-FRL Professional Binocular Stereo Zoom Microscope is designed for professionals needing high-quality magnification and ergonomic features. With a magnification range of 7X-90X and a 0.7X-4.5X zoom objective, it allows for detailed inspections of large specimens. The microscope includes a bright 8W fluorescent ring light for optimal visibility and a double-arm boom stand for versatile positioning, making it ideal for circuit boards, dental appliances, and more.

## Description

The AmScope SM-4BY-FRL professional stereo zoom microscope has a pair of 10x super-widefield high-eyepoint eyepieces, a 0.7x-4.5x zoom objective, a 2.0x Barlow lens, and a double-arm boom stand. The microscope has an overall magnification range of 7x-90x. The binocular viewing head has an interpupillary range of 55 to 75mm, a 45-degree inclination to reduce eye and neck strain, and 360-degree rotation to enable sharing. The WH10x20mm super-widefield high-eyepoint eyepieces combine with the 0.7x-4.5x zoom objective to provide continuous zoom magnification and a longer working distance for inspecting large-scale specimens that require handling or repair. The microscope comes with a 2.0x Barlow lens that can be added to the objective to increase the magnification range. A Barlow lens with a magnification greater than 1.0 increases the magnification and reduces the working distance. High-eyepoint eyepieces ease viewing for users who wear glasses, and dioptric adjustment accommodates individual eye-strength differences. A stereo microscope, sometimes called an inspection or dissection microscope, has low magnification and a long working distance that enables users to manipulate the object being inspected. The removable 8W fluorescent ring light provides cool, white light for observing specimens as they would appear in their natural environment. A ring light provides shadow-free illumination. It has a 2-3/8" inner diameter and uses a 110V-120V power supply. The microscope has a double-arm boom stand that enables users to position the microscope head on all three axes (X, Y, and Z). Bilateral focus eases use for left- and right-handed users. The stand has 20" double arms, and a 30" overall length. The pillar is 17" and the focus rack has a 3" diameter. The solid cast-steel base is 2 x 8-1/4 x 10-1/4 inches (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; D is depth, the horizontal distance from front to back).SpecificationsHeadBinocularMagnification range7x-90xZoom objective power0.7x-4.5xEyepieces (DIN, 30mm)WH10x20mm high-eyepointZoom range13:1Field of view1-1/4"Optical working distanceUp to 4"Microscope standDouble-arm boom standHead movementX-, Y-, and Z-axesIllumination typeEpiscopic (reflected)Light sourceFluorescent ring, 8WPower110V-120VMicroscopes 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.United Scope manufactures microscopy equipment and accessories under the brand name AmScope. The company, founded in 1996, is headquartered in Irvine, CA.What's in the Box?AmScope SM-4BY-FRL stereo zoom microscope with double-arm boom standWH10x20mm eyepieces, 30mm, one pair0.7x-4.5x zoom objective2.0x Barlow lensFluorescent ring light, 8W (FRL8)Focus rackEye guards, one pairInstructions
