## Overview

The AmScope T340B-DK-LED is a professional-grade trinocular compound microscope offering up to 2000x magnification with achromatic optics, dual brightfield/darkfield LED illumination, and a durable double-layer mechanical stage. Its ergonomic Siedentopf head reduces strain during long sessions, while the trinocular port supports high-quality imaging. Ideal for advanced biological research, education, and lab professionals seeking precision, versatility, and seamless digital integration.

## Description

The AmScope T340B-DK-LED compound binocular microscope has interchangeable pairs of 10x widefield and 20x widefield eyepieces, a reverse-mounted nosepiece with four DIN achromatic objectives, Brightfield/Darkfield (BF/DF) LED illumination, and a double-layer mechanical stage. The vertical trinocular port can be used as a C-Mount or 23mm photo port (camera sold separately). The Siedentopf binocular head has 48 to 75mm inter-pupillary adjustment, fixed 30-degree vertical inclination to reduce eye and neck strain, and 360-degree rotation capability to provide a more comprehensive view and enable sharing. Bilateral dioptric adjustment accommodates individual eye-strength differences. The reverse-mounted nosepiece has 4x, 10x, 40xS (spring), and 100xS (spring, oil) DIN achromatic objectives that combine with the eyepieces to provide color correction of magnified images. The 40xS objective is spring loaded to prevent slide damage when focusing. The 100xS spring-loaded oil objective provides increased resolution over a standard objective. A reverse-mounted nosepiece keeps objectives out of the way to prevent damage, and to enable more secure slide handling. A compound microscope is used for inspection and dissection of specimens when two-dimensional images are desired.The microscope has Brightfield/Darkfield (BF/DF) illumination. Brightfield (BF) illumination allows the specimen to absorb light, resulting in a dark image on a light background, and Darkfield (DF) illumination reflects light off the specimen, resulting in a light image on a dark background. LED illumination provides bright, cool light for working with temperature-sensitive or live specimens. The 1.25 NA Abbe condenser can be adjusted to control the distance of the light from the stage and has an iris diaphragm to optimize the amount of light illuminating the specimen. The 0.7 to 0.9 NA darkfield condenser blocks the central portion of the light path to produce a darkfield image. The double-layer mechanical stage, with 1mm stage divisions, locks the slide into place and provides precise slide manipulation along the X- and Y-axis to allow coordinates to be recorded, enabling the viewer to return to a specific location on the slide. Graduated coaxial focus control allows measurements to be taken. The enamel-coated cast-steel body is durable and resistant to stains and corrosion.

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.

Review: I love this Microscope! - This is a great Microscope! My 10 year old daughter has been set on becoming a Paleontologist since she was around 6, so for her birthday this year we decided to get her a Microscope. My friend who is a gemologist suggested that we get a binocular microscope. I started doing some research and decided that I also wanted a camera port so we could easily photograph what we were seeing. Some more research into halogen vs LED, quickly pointed out the superiority of LED for longevity of bulbs and since they are much cooler they avoid overheating delicate specimens. I then learned about Darkfield... Just do an internet search for images using "Microsocope and Darkfield" and you will see why I decided this was a "must have" feature (we use darkfield as the default mode for just about everything we view) I also wanted a microscope powerful enough to see really interesting things (so minimum 1000x). I then started searching and quickly narrowed it down to this microscope, and we have been super happy with it. I separately purchased an AmScope 3.0 MP camera AmScope 3.0 MP USB2.0 Microscope Digital Camera + Software 3.0 MP, Compatible with Windows XP/Vista/7/8 and Mac OS 10.6 & Up , figuring I could upgrade the camera later if necessary. We are really happy with the camera, and for us 3 MP is more than enough - It works perfectly with this microscope. We hook up a laptop and are able to see on the computer what the person looking through the binocular lenses is seeing so no one is bored. The ToupViewX software that comes with the camera is amazing as well, It has all kinds of features to let you filter the image, lay down rulers, zoom, etc. It is for both Windows and Mac, although the Windows version is much superior - the Mac version appears to be a port and not all features are yet there. My nephew is a biology student at U of Md and when he came to visit he was very excited to use this microscope and commented that this microscope was better than what they use. He showed us how to get the most out of the microscope, including how to use the oil when zooming in with the most powerful lenses. Considering all you get, the price is great! It arrived right on schedule, well packaged and in good condition. I also ordered various prepackaged slides with interesting things to look at so we could get started right away. My daughter is really happy with it, and loves showing it to friends. The only two improvements I think I could make to this Microscope: 1. It would be nice to have a light above the specimen as well which could be used when looking at thick objects that aren't transparent - this is not standard on most microscopes, and we just keep a separate lamp nearby to shine on those objects. and 2. It would be nice to be able to separately adjust the focus for the camera so it would exactly match the focus of the eye pieces - this is, perhaps, more a limitation of the separate camera than the microscope, and perhaps there is a focus attachment available I don't know about.
Review: Great microscope but the LED is only 1 watt, not 3 watt - As another reviewer said, this is advertised as a 3 watt LED, but it comes with only a 1 watt LED, which falls short for some dark field uses. However, I found a cheap 5 watt LED power module and 5 watt LED assembly kit to upgrade it to 5 watts. The upgrade was not easy, but it only cost $17.00 on ebay, so it was well worth the time and effort. Other than the 1 watt LED, it is a very nice microscope.

### ⭐⭐⭐⭐ Really great scope for the money
*by J***D on April 26, 2016*

Images: I've put up a series of images taken through the 40x. The first one is shot through the eyepiece (followed by a detailed crop of that image). After that we have images shot right down the camera port. You can see how much the eyepiece restricts the field of view, and also how much it increases the apparent flatness of the image by cutting out the outer edge of the lens where most warping and aberration occurs. The light is biased so that I could get a better look at the shape of the cells. Update: After a couple of weeks of use, I still like it quite a lot. I have decided to dock a star for the eyepieces, though, and because I've found that the filter holder is slightly off center, which makes it impossible to get a stop filter to work properly with the 40x objective. I'd consider carefully if you want to actually use the camera port. I kind of like it, but realize that half your light is going up this third pipe instead of into your eye. It's convenient, but I wonder if I shouldn't have just used a binocular port instead. There are some limitations to how you can upgrade the scope as well. There doesn't seem to be a path to add Kohler illumination for instance. The led light and the frosted lamp focusing lens actually works very well to produce a nice, even light. But there is a little irregularity left to it, and if you wanted to take it that extra mile, it just doesn't seem to be possible. The lamp is more than bright enough under most conditions, but when adding filtering or using the 100x objective, you might wish it was a little stronger. About the 100x and the oil. I'm really not sure the 100x is worth it. I'm not sure you see that much more detail in the 100x than you can see in the 40x, and the chromatic aberration is much worse. It's also kind of a pain to switch to oil, and the focus is /way/ out from the 40x, so it's a little tricky and it's possible to completely lose your focus. I'm adding a few images I took tonight of a living blood sample as examples of what you can see through the scope and the image quality you'll end up with when using it. -------------------------------------------------------------- Original: First this is based off of just a day of usage, so basically here come initial impressions. I may revise later. I'm very happy with the quality and capability of the scope. My previous experience with microscopes are just what I had in high-school and college. This scope is better than anything I've used before. The scope seems to be very solid mechanically: It uses solid metal construction with the exception of a few dials and the lamp lens-holder. The focus moves fluidly and precisely and holds position perfectly. The mechanical stage also works very well, and the slide clamp is a nice touch. There are two low-points, mechanically: #1 - The head is secured by a single screw which makes sure a lip on the head shaft is pushed under two overhanging notches. When the screw is fully installed the it pushes the head and tilts it very slightly to the side. This doesn't seem to cause any imaging problems, but it just doesn't feel right. #2 - The camera port doesn't have any way to adjust focus. I knew this when I ordered, but it would just be really nice to have a way to keep the camera and the eyepieces in focus together. I'm going to experiment and see if this can't be done by putting a fixed spacer in front of the camera mount. Optically this system is pretty nice as well: The light is bright and neutral colored. It does get hot, but not /too/ hot. Living things do tend to stay living for a while. The filter holder is convenient to access (though very shallow), and the iris works smoothly and firmly. The objectives are better than I expected. They feel heavy and sturdy. I thought they looked kind of cheap in the photos, but in person they are pretty nice. They are solid steel, brass, glass and rubber. The 4 and 10x are in perfect focus across the field. The 40x is flat across maybe 90~95% and the the 100x starts to get a little fuzzy somewhere under 90%. There are several flaws in the optics though: #1 - The focus is not perfectly matched between each objective. When moving from 10 to 40x, I have to turn the fine adjustment more than a quarter revolution to refocus. Going from 40 to 100x is even worse, with or without oil it's pretty difficult to find the focus. I think it's more than a full fine knob revolution out. #2 - None of the eyepieces are great. The 10x "Widefield" is just not that wide. It's not bad, but you're definitely trapped in a little circle that blocks out three fourths of your normal range. The worst part about the 10x is the relief, though. I have to force my eyes open as wide as they'll go and press my lashes up against the eyepiece. It feels like my eyeball is about to touch the glass. It's absolutely impossible to wear your glasses, so consider if you need more than the simple correction options built into the head. On top of that, one of the 10s seems to have some sort of flaw that blocks a very small portion of the view (turning the circle of light into a flat tire of light). The 20x pieces were surprisingly good after that. They look cheap from a distance, but up close the construction is clearly better. Even though they are smaller, they're heavier than the 10x. I'd say that the 10x was designed to look nice, and the 20x was designed to work. The field of view might actually be slightly bigger than the 10x, and the relief is definitely better. I've switched to the 20x as the "normal" piece now. Even for the 100x objective it's better. Yes you see more diffraction patterns and there really isn't much more detail than you can see in the 10x, but I find it's still nicer to have the image blown up a little further. Neither design is exactly good, and I think I may spring for a better set as one of my first upgrades. Strangely all the AmScope lens upgrades are for 30mm mount. This looks like one area where Omax is doing better. Other notes: Take the oil out of the box and throw it straight in the trash. Actually you might want to wear gloves while you do that. Some of it has probably seeped down the side of the bottle. This stuff stinks, gets everywhere and burns the eyes. It's ceder oil, and while very traditional it's not very good compared to what's available now. If you're getting this scope, buy some synthetic objective oil that won't evaporate and plasticize. That way you don't have to clean the oil off if you're not going to use the scope for a little bit. The download key for the manual is on the outside of the box. I was tempted to get the dark-field condenser model, but then saw it was air only. So instead I colored in a circle on some clear plastic packaging material and saved $50 with a home made stop filter. It works great on 4x and 10x, and sort of decently on 40x. Maybe I'll buy a dark-field oil condenser some day and be able to do 100x. If you want to try this, I made the circle the exact size of a nickle. I doubt this is the perfect size, but it did work. Another simple mod you might try is covering half the lamp lens with some paper. This biases the light, providing amazing contrast and lets you see a bit of depth so the critters no longer look like squashed circles. Like another reviewer, my scope had no branding or markings. I don't really care, but it's kind of funny.
