## Overview

The AmScope SM-3B is a professional-grade binocular stereo zoom microscope offering a versatile 7x-45x magnification range via a continuous 0.7x-4.5x zoom objective. Its ergonomic design features 10x super-widefield eyepieces with adjustable interpupillary distance and a 45° inclined head to reduce strain. Mounted on a single-arm boom stand with extensive reach and 360° rotation, it enables easy manipulation of large specimens like circuit boards or dental appliances. Ambient lighting eliminates the need for power sources, while a robust cast-steel base ensures stability and durability, making it ideal for professionals and serious hobbyists alike.

## Description

The AmScope SM-3B professional stereo zoom microscope has a pair of 10x super-widefield high-eyepoint eyepieces, a 0.7x-4.5x zoom objective, and a single-arm boom stand. The microscope has an overall magnification range of 7x-45x. 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. 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. Ambient lighting illuminates the specimen, eliminating the need for power or batteries. The microscope has a 17" pillar that has an 8" vertical working distance. The 16" single-arm boom has a 24" overall length. Bilateral focus eases use for left- and right-handed users. The microscope head can be rotated on the X- and Y-axes. The solid cast-steel base is 1-3/4 x 9 x 9 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-45xZoom objective power0.7x-4.5xEyepieces (DIN, 30mm)WH10x20mm high-eyepointZoom range6.5:1Field of view1-1/4"Optical working distanceUp to 4"Microscope standSingle-arm boom standHead movementX- and Y-axesIllumination typeN/ALight sourceAmbientPowerN/AMicroscopes 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-3B stereo zoom microscope with single-arm boom standWH10x20mm eyepieces, 30mm, one pair0.7x-4.5x zoom objectiveFocus rackEye guards, one pairInstructions

Review: and I like that it is dimmable too - This is my very first microscope (which I bought on sale for under $300.00 from the desertcart warehouse) fully meets my expectations. I took a chance on a damaged box item for the sales deal and was a winner! It was just missing a couple of thumb screws which I picked up at a local hardware store for several bucks. Now I have a heavy, professional unit for my home use in studying and identifying rocks and minerals. I went with this boom-version so that I could use it for looking at larger samples, and for examining printed circuit boards and other larger items. The 80 LED light provides all the light I need, and I like that it is dimmable too. As a geologist, I have found that the 7.5X to 45X magnification range is perfectly sufficient for studying minerals and grains within rocks for sample identification. Sure, one could live with a 10x hand lens, but this 'scope provides a nice field of view without distortion while providing good illumination.There are other cheaper units with fixed magnification where you need to swap out the lenses, but trust me, the variable magnification is really the way to go! It is made of appropriate construction materials that will have it lasting for many years; I expect to hand it to my grandchildren. It is solid and heavy indeed... I have no fear of it tipping. It is large, and a boom mount unit might not be appropriate for all users, especially if your space is limited. If you feel you need different magnification beyond the 7.5X to 45X range, other lenses are available for this microscope.
Review: Can't go wrong for the money - I purchased this scope for surface mount electronics work. For the money, you really can't beat it. I am used to working with microscopes at work that cost $10,000 to $20,000. In comparison, I would say this scope is like a Toyota Corolla vs. a Porsche. Both will get you to work and back in the same amount of time, but one is 1/10th the price. Also, for those of you who are wondering, the 3.5x minimum zoom is not necessary for surface mount electronics work. 7x is fine with plenty FOV. First, the scope is very well packed in the box. Everything is encased in a custom block of styrofoam. Second, the image quality is surprisingly good, and the 80 LED light is plenty bright, even at maximum zoom. I find the field of view plenty for electronics work. There is some refocusing required during zoom, but its fairly minor and to be expected at this price. Only at maximum zoom do you begin to notice chromatic aberrations and image distortion, but it is still low and perfectly usable. The stand/boom is also surprisingly stable, although you do get some shaking at maximum zoom. It even comes with a nice vinyl dust cover for the entire unit. The one fault I find is that the interpupillary distance adjustment is a little funny. I'd prefer to adjust the distance a little wider, to leave a little space for my nose, but then the image goes away. So I end up having to put the eye pieces very close together. Although I have a slightly smaller IPD than average, the issue seems more pronounced with this scope.

### ⭐⭐⭐⭐ Good value, works well for 0402, 0201 and TSSOP rework, LED ring can get in the way though
*by T***Y on January 17, 2015*

I got this for a home rework lab. It is super convenient and works well. The build quality is very good for the price, and while not the same as higher end lab-grade stuff, it is plenty good for hobbyist use. The only gripe I have is about the short focal distance. When used without the LED ring attachment, it is easy enough to get to the workpiece, but the LED attachment really eats up a lot of space and the working room for irons and tweezers is too limited. The light ring really puts out a good amount of light, so working without it is a hassle, but I do need to remove it sometimes when I am dealing with complicated assemblies where I need a lot of freedom to move my hands and tools under the scope. I am probably going to build a new light rung myself that site higher up and out of the way.
