The AmScope SM-3T 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 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. 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).

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.

This microscope instantly elevated my ability to fix watches, its amazing what you can accomplish if you can see what you're doing. The microscope arrived well packaged and was not too challenging to set up, and it pretty simple to use. The image is very clear and easy to focus if changing zoom levels or working distances. I did purchase the reducing lens to give myself more room to work under the microscope, and I also purchased the LED light ring. All told, for approximately $500 you get a very capable microscope that will help you perform any task in watch making. For example, prior to buying this, I couldn't lubricate and replace a cap jewel to same my life, I must have ruined a dozen watches just because the cap jewel would fly away simply because my loupe didn't give me the vision required. Since buying the microscope, I haven't lost a cap jewel yet. If youre serious about watchmaking, this microscope will make your experience 100% better.

This product arrived with a missing eyepiece. Ampro requested a copy of my invoice, which I sent them, then stopped all communication. I've even tried emailing the CEO of Ampro, but gotten no response. Avoid this company!

I purchased this microscope based on a review on another channel. The reviewer purchased this microscope, along with a .5X Barlow lens, an LED ring light for illumination and a digital camera. I purchased the same items as he, to duplicate his setup. After setting up the microscope, I had several small boxes left over. Opening one was an LED ring light. Another small box had a .5X Barlow lens, and another had a 2X Barlow lens. The final box had a camera, complete with a power supply, camera adapter and a USB cable. I returned all the light, lens and camera. The box also contained a plastic cover for the whole setup. None of these extra items were in the description, so I was pleasantly surprised. 5 stars and a big thumbs up.

I really like the ease of use and the image quality. I use a 0.5X Barlow lens and my workspace opened up quite a bit. Everything was packaged well and easy to setup.I don't like that you lose the left eye when you enable the camera function. The push pull rod for the camera view takes away the left eye when in the camera position. You can still use the right eye with the camera, but you will not be looking in stereo. Aside from that, it is great!

I like the ease of this unit, which I use for watchmaking. It’s heft makes for a steady presence on the bench. The optics are clear and easily adjustable. I especially like being able to view items without removing my eyeglasses. My daily use of the loupe has declined by 90+%. Less back and neck strain (not having to hunch over the impossibly tiny watch movement parts. Highly recommended.

Hello!So i have been looking through "the jungle" for my purpose: Watch Repair. I am studying to Watchmaker and this was exactly what i was looking for. The package came quickly to Sweden (3 days!)The package does not include any instruction but that is not a problem because there are not many parts and by the photo of the Microscope you can see how the Microscope is built.I think there should be an integrated light with this one because of the price but its not a problem just remember to buy some light for your workshop. It will help alot!Shipping was quick! I am satisfied with this product and i can recommend it to others!If you want, you can buy a camera and attach it like i did. It is perfect!I don't regret buying this because i am using it every day!Thank You!

I use this microscope for watchmaking. It is absolutely perfect. In fact, it's an actual Game Changer for watchmaking. I can't believe I ever did this with only a loupe. A few tips for a new user:The microscope is incredibly easy to set up and fully adjustable. If you adjust it correctly, it can safely hang over the edge of your desk so you can sit fully upright in a comfortable chair while working. This would be the same for circuit boards, jewelry making or anything else where the space permits. For watchmaking, the 0.5 Barlow lens is critical since you need the space to work underneath the microscope. Also, my preference is NOT to sit directly above my items. Remember you have binocular vision with depth of field so if you're directly on top you can't work well. Angle the microscope a bit pointing 70-80 degrees instead of direct 90 depending on your preference.Pro Tip: Adjust the eyepieces all the way to their 'default' or 'original' point screwed clockwise. Now adjust the zoom to MINIMUM. Then adjust the main knob that says 'Tension' on it to be level top and bottom or in the 'center' of the mechanism's adjustment threshold, i.e. not all the way up or down, but in the middle. This is default ZERO stop. Now adjust the whole assembly's boom arm up or down until A.) you are sitting upright and comfortable and B.) you are closely or almost focused on an object sitting at work height. Now, and only now should you adjust your eyepieces to get the focus crisp and correct since you will not be able to focus fully by adjusting the boom (movements will be far too coarse!). Remember eyepieces should be adjusted for each eye individually with one eye closed at a time.Are you in focus? Okay, now zoom all the way in on your work piece at MAX magnification. Now adjust the Tension knob (the big one) to make focus crystal clear at MAX mag. Now use the zoom knob to zoom out all the way. You should still be in focus. In this way you can zoom in and out with very little adjustment IF your workpiece remains at the same working height. In other words, you should only be using the magnification knob most of the time, with fine adjustments for objects at varying heights on the table or workspace.Lastly, get a ring light, a great desk light as well that is moveable and a camera. Enjoy. I can't believe we live in a time where a microscope like this is sub $10,000. Amazing time to be alive.

Calidad aceptable, pero tiene varios detalles que hay que considerar y seguramente están relacionados con su precio. 1) El detalle más importante es que los tornillos del brazo horizontal no fijan la barra y el microscopio inevitablemente gira. Lo solucioné al revisar internamente la pieza y notar que le falta una lámina que es la que presiona el tornillo para fijar el brazo. Le comparto mi solución: utilicé una lámina para calibrar bujías de auto, menor a 0.010, para cada tornillo del brazo y listo! 2) El tornillo de enfoque no es preciso y tarda uno bastante para lograr una nitidez aceptable. 3) El cubre objetivo de los lentes inferiores no enrrosca bien y se cae. Por lo demás funciona aceptablemente, yo lo uso para obtener microfotografías de rocas y minerales. Tal vez sea también útil para relojería. Lo voy a probar.
