Description

The AmScope SM-4TZ-144A professional trinocular 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 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. The removable 144-bulb LED ring light has four separate zones to independently control light intensity and direction. The ring light provides bright, cool light for working with temperature-sensitive or live specimens, and shadow-free illumination. A rheostat controls the amount of light emanating from the lamp. Power and adjustment controls are located on a control box to speed adjustments. The ring has a 2-1/2" (64mm) inside diameter and a 4" (100mm) outside diameter. It has a 100,000-hour life span and a 110V-240V variable 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).SpecificationsHeadTrinocularMagnification range3.5x-90xZoom objective power 0.7x-4.5xEyepieces (DIN, 30mm)WH10x20mm high-eyepointTrinocular portC- Mount or 23mmField of view2-1/2"Optical working distanceUp to 8"Microscope standDouble-arm boom standHead movementX-, Y-, and Z-axesIllumination typeEpiscopic (reflected)Light sourceFour-zone 144-bulb LED ring light with rheostatPower110V-240V 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.

  • Great hobby scope!
Style: Microscope
I purchased this for my hobbies in geology and archaeology and it has been outstanding - with a couple of caveats. This microscope has no stage, and many of my specimens are too small to see without raising them to the lens, so I had to solve for a workable stage that I could set rocks and other hard sharp objects on. I ended up using a small laboratory jack (Sold on Amazon as well) for the stage allowing me to put a specimen on it and raise it to the approximate required level, and then using the microscope for the final adjustments. This has worked out perfectly. I read about the horizontal rails on a similar model becoming pitted due to being undersized for the bearings rolling against them. With this in mind, I always carefully apply upward force to the heavy end before rolling it and have seen no pitting. No sense taking any chances - I want this microscope to last. The lens are perfect for my hobbies, and the ability to zoom is especially useful. The light source is really useful as well - it is bright and you can adjust the direction of the light by turning off some of the LEDs. The unit is incredibly big and heavy - I didn't realize just how big and heavy until I assembled it and then decided to move it. It was too long to fit in the appointed spot in my lab, but luckily because it will turn every which way, I ended up sitting it up sideways instead of longways and it works fine. You will have no problem with the unit accidentally moving (unless of course the table its on collapses!) as it is very heavy. I purchased this unit with the idea of someday attaching a camera, but have not done so as yet so I can't speak to that function. Movements are all smooth and have a professional feel to them. Overall this has been a wonderful purchase with one small hitch... You must assemble the unit from several parts - and the manual that came with my unit did not apply to the microscope I purchased. Weird. Most of the assembly was straight forward and being a man (I hate to ask for help) I finally figured out the few odd attachments you must make. Overall it was a fun puzzle to solve, but most people would likely prefer to either receive the correct assembly instructions or look them up online. It took about 30 minutes to assemble (and most of that was scratching my head over 1 part). ... show more

  • Excellent for watch repair
Style: w/ 144 LED Ring Light + 5MP Camera
Plenty of room to work using the .5 Barlow. Simple assembly, LED is super bright. Plenty of physical adjustments. Can sit comfortably and work all day. Fits on my rather small (39”x24”) Workbench. Stable yet not too heavy. Super optics. Haven’t used the camera yet.

  • Its heavy, beautiful and really good optics. There is only one minor issue I had with it.
Style: w/ 144 LED Ring Light
I wanted to be able to solder with a live view on the monitor and inspire my kids to like science with looking at Geodes and other things. I bought the 4k Amscope camera on it and a 32 inch monitor and its amazing. The Geodes look great with the optics. I wish I would have gotten the 4K monitor but will have to give to the kids and buy it again. The camera with this scope really makes it fun. The problem I had was when I added the camera. The little screw that holds it from sliding down the post has a little rubber tip so it does not scratch the main post and hold it in place. It works when the camera is not attached but you either have to really tighten it or I bought a little pole vice and I put it in the pictures to this review. Its high qualify, great optics and worth the money. The monitor resolution is 1900 by 1080 and the image looks great but can only imagine with 4K monitor. ... show more

Style: w/ 144 LED Ring Light + 5MP Camera
Good value, but narrow field of view. The camera and software is total garbage. Better off taking a photo through one of the eye pieces with your phone. Use it for bearing failure analysis.

  • I have had this for years now and love it.
Style: Microscope
The scope works as good as some of the ones I used in the Entomology lab at University of Florida and better than most of the student scopes. The base is solid providing stability and the swing arm allows easy access while easily moving out of the way. The LED light ring I bought with it has been more than capable to adjust to multiple insect sizes. Its adjustability provides a wide range of bright to dimmer light for small translucent wings or hard dark beetle shells I need to count pits on for identification. I use it for insects ID in the 2 mm size and up. I will be ordering a wall mount swing arm in the near future for my new office, but this scope and stand are better than I expected for the price after years of use. ... show more

  • Incredible scope for the price
Style: Microscope
This scope is a true bargain. The optics are as crisp and as sharp as any name brand professional scope that I have used. The boom stand is not all it could be since the moving parts do not lock down without torquing the compression levers and knobs with all of my strength but it is still quite functional. I am using a full frame Nikon 810 camera on the C mount camera tube and it works quite well (the Nikon camera mount is not included and can be purchased separately from AmScope). The camera can not be locked into the mount with a set screw,and can turn if touch but I have not found that to be problematic. One annoying feature of the optics when using the 2x lens to acquire the 45 to 90 x magnification range is that the field is quite curved but this aberration can be removed in Photoshop. Regardless of these minor limitations, I definitely will not be sending this scope to back to Amazon! ... show more
