## Overview

The AmScope SM-4BZ-FRL Professional Binocular Stereo Zoom Microscope is designed for precision and comfort, featuring a wide magnification range of 3.5X-90X, ergonomic design to reduce strain, and a powerful 8W fluorescent ring light for optimal illumination. Its double-arm boom stand allows for versatile positioning, making it ideal for inspecting large items like circuit boards and dental appliances.

## Description

The AmScope SM-4BZ-FRL professional stereo zoom microscope has a pair of 10x super-widefield high-eyepoint eyepieces, a 0.7x-4.5x zoom objective, two Barlow lenses, and a double-arm boom stand. The microscope has an overall magnification range of 3.5x-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 coms with 0.5x and 2.0x Barlow lenses that can be added to the objective to increase the magnification range. A Barlow lens with a magnification of less than 1.0 reduces magnification and increases the working distance, while 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 range3.5x-90xZoom objective power0.7x-4.5xEyepieces (DIN, 30mm)WH10x20mm high-eyepointZoom range26:1Field of view2-1/2"Optical working distanceUp to 8"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-4BZ-FRL stereo zoom microscope with double-arm boom standWH10x20mm eyepieces, 30mm, one pair0.7x-4.5x zoom objective0.5x Barlow lens2.0x Barlow lensFluorescent ring light, 8W (FRL8)Focus rackEye guards, one pairInstructions

## Customer Reviews

### ⭐⭐⭐⭐⭐ Quality Microscope for a good price.
*by J***E on September 1, 2020*

Having owned this 3.5 to 90X Am Scope for over 5 years, I am very pleased with it.I paid less than $300 for it and it is very similar to the $2000 microscope I purchased and used in my Circuit Card Repair shop in the Air Force.The dual arms make it much more stable than a single arm model and the base is heavy to prevent tipping.I use it in the 7X to 45X configuration (10X eyepieces with no .5X or 2X Barlow lens) which gives me a 6 inch working distance between the bottom of the lens and the table. This allows plenty of room for working with a soldering iron.The ring light is adequate, but I like to use a separate LED lamp to provide better depth perception. Having a goose-neck light would be ideal.Unlike fixed magnification microscopes, this one has a zoom which allows me to solder at a lower setting and then easily zoom in to inspect my work. It is also simple to focus.

### ⭐⭐⭐ The other microscope has a bad potentiometer. It is probably a $3 part and ...
*by D***T on February 22, 2017*

The microscopes themselves are decent for what you pay.That said, the electronics are below average. I have multiple Amscope microscopes and I have had lights go out on two units. One unit I took the LED control box apart and desoldered/resoldered a cold solder joint on the PCBA.The other microscope has a bad potentiometer. It is probably a $3 part and I did the troubleshooting. The company doesnt want to simply send me a new part for a microscope that is 5 weeks old (I am going to repair it). After I have spent time going through and troubleshooting what is wrong, they have the nerve to ask me to pay shipping.Microscopes are pretty good for what you get. The electronics leave a lot to be desired and you are on your own if something goes wrong.

### ⭐⭐⭐⭐⭐ Criticle Buyer
*by C***R on June 19, 2015*

Product is great as was the service . I use this for many inspection applications . Not for Biological purposes that's a different unit . I would suggest getting the led light in stead of the florescent but that was my mistake . I would recommend this to any one wanting a quality professional scope . Its heavy duty I love it .
