## Overview

The AmScope SM-3TZ is a professional trinocular stereo zoom microscope offering a versatile 3.5x-90x magnification range via a 0.7x-4.5x zoom objective and dual Barlow lenses. Its ergonomic 45° inclined head with 10x super-widefield eyepieces reduces strain and supports 360° rotation for collaborative work. Mounted on a robust single-arm boom stand with extensive vertical and horizontal reach, it enables manipulation of large specimens. Ambient lighting provides clear illumination without power, making it ideal for detailed inspection in labs, manufacturing, and research environments.

## Description

The AmScope SM-3TZ 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 3.5x-90x. The trinocular 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 vertical trinocular port can be used as a C-Mount or 23mm photo port (camera sold separately). 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 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. 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).SpecificationsHeadTrinocularMagnification range3.5x-90xZoom objective power0.7x-4.5xEyepieces (DIN, 30mm)WH10x20mm high-eyepointTrinocular portC-Mount or 23mmField of view2-1/2"Optical working distanceUp to 8"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-3TZ stereo zoom microscope with single-arm boom standWH10x20mm eyepieces, 30mm, one pair0.7x-4.5x zoom objective0.5x Barlow lens2.0x Barlow lensFocus rackEye guards, one pairInstructions

Review: Pretty good for the price - Not bad for something in the $500 price range. The stand is very heavy and solid, the optics are good, and the controls are nice and smooth. The manual is a joke, but hey anyone buying this should know how to setup a microscope. The focal point was a bit closer to the objective than I would like, and it would be nice if you could zoom out some more, but like I said for the money this is not bad at all. It also came with a dust cover.
Review: Super great microscope - Super great microscope, especially for the money. I use this for settling gemstones and it works great. I recommend getting the 144 LED ring light to go with it as the fluorescent one that comes with it isn't really bright enough.
