The AmScope SM-4TZ-FRL professional trinocular stereo zoom microscope has interchangeable pairs of 10x and 20x 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 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 and WH20x10mm 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.
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).

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.
United Scope manufactures microscopy equipment and accessories under the brand name AmScope. The company, founded in 1996, is headquartered in Irvine, CA.

A real stereo microscope is something every electronics hobbyists should have on their bench. This may not be made in Germany or Japan, but it does the job well and the value for money is there. I should have made this purchase years ago!

Très bel appareil destiné pour ma part à intervenir sur des cartes mère de smartphones. Le choix de la fourniture par Amazon permet une économie substantielle sur le transport. Il est arrivé bien protégé et en parfait état. J'avais quelques craintes vu le poids et le prix de cet appareil. Dommage qu'il n'y ait pas de systèmes pour bloquer les oculaires alors que des trous sont prévus à cet effet. Je pense en fabriquer. Je pense aussi en commander d'autres pour obtenir un grossissement plus important. Mais tel qu'il est équipé c'est suffisant pour ce que je veux faire.

As a metal detector user and meteorite hunter, this was just what I needed! But, that the quality could be like this, was something I never thought possible! It`s so great!

First...I am NOT a professional microscope user. I can only review this from what I needed and the price point I was willing to spend. I build scale models out of brass, copper, and aluminum. Some of the detail that I as striving for is very fine. I was using one of those lighted magnifiers on a boom, but even those weren't even strong enough for the detail I am striving for. Hence...the search for a microscope.I bought this particular model with the florescent light ring. Since I am working with reflective metals, I felt the LED lights were going to be too bright. My shop already has florescent lights, so I thought it would be best to go with the florescent ring light.I called the sales department with a few questions (one being the light choice which the salesman agreed with my logic) and I received satisfactory answers to everything. I also had an idea of the answers and he actually just reaffirmed that I was making the correct choice.I used the microscope for the first time this weekend, soldering some parts together that the amount of solder used is crucial so as not to blob it. The microscope worked perfectly for the task. I can now see what I am doing!I was surprised how heavy this thing is and how well built it feels. I was really wondering about the quality because I saw various other microscopes costing well over double for what I paid for this.As a caveat...I have no idea how this would compare to something that costs $2000, but for me and my $500 budget, it works perfectly. I bought the trinocular version because I wanted the capability to add a camera to the unit at a later date.
