T690C Trinocular Compound Microscope, 40X-2500X Magnification, WH10x and WH25x Super-Widefield Eyepieces, Infinity Objectives, Brightfield, Kohler Condenser, Double-Layer Mechanical Stage

I conduct a lot of fungi collection projects and this scope has been great. Well built, hefty, great clarity with objectives, and smooth controls. Only limitations for clarity is the camera you choose and your skill level.

I bought a Amscope microscope, and kept within box until 2 months later. So, with some use, this objective was not working anymore: final lens unglued, and worst, immersion oil was spread insight objective's body. My Hope is that you warrant a brand new objective, since ita was not related with misuse. Anyway, I really appreciate this microscope: robust precise and very qualified optics. I am sure my next microscope will be American Opticl again.

Excellen quality product. Fast service. highly recommended. Fantastic price. A very professional grade instrument.

Excellent imaging tool, esp.for microphotography! Optics are superior to non-achromatic objectives in that the peripheral areas remain in focus with the achromatic lenses. With my Varimag adapter I am able to shoot and Live View slides without the usual vignetting, so little to no editing of images are necessary. Technical support is wonderful. The manual is horrible as it not comprehensive and much guess work and trial and error are likely in figuring out the various controls. A very worthwhile investment, overall.

When you pay for a microscope like this, you have to assume you’re not getting an Olympus or a Nikon, which is the case. I use this microscope at home, for diagnostic pathology review and CME. Works fairly well for that. However, it’s not parifocal between magnifications. If you expect the image to stay sharp between 4x and 10x, this is not the microscope for you. On the other hand, its not wildly off, so I don’t think it’s that much of a problem. The camera is not parifocal with the microscope either, so you have to focus it separately on the computer screen, which is not easy. I tried taking several pictures moving the focus know slightly between each picture, and then did stacked them using other software. That worked pretty well, but it’s added work. Also, I have not been able to use the Mac version of the software because it’s not approved by Apple and the OS will not let it run, but the Windows version, which also has more functions, works. The software is not great, but functional, once you get the hang of it. You do have to do the white balance adjustment, but one you set it, you don’t have to do it again. If you don’t know what this is, and your pictures are horrible, you need to read more about photo microscopy. The other major problem with the camera, and the microscope itself, is that, at 4x, there is a central hotspot and significant vignetting. There is a claim of even Koehler illumination, but this is not true at 4X. This is not as noticeable at 10x, and absent at 40x. The images were also too bright. You need to set the exposure to “Manual”, and adjust it yourself. This made much better pictures. As for overall sharpness, a tough of increased vibrancy and sharpness with Photoshop or Lightroom works well, after you’ve done your focus stacking. Images taken with more expensive microscopes often need this too. I tried the oil immersion lens. Worked well. It’s not used often, but when you need it, you really need it. Pictures are a tad soft, and lack contrast, but you can fix that in your favorite picture remediation software. The microscope itself is built like a tank, and is quite heavy and solid. If need be, you can use it as a weapon. Overall, although not a premium microscope, the view through the eyepiece, and the pictures you take, are serviceable, assuming you know what you’re doing. Clearly, the ability to see what you need to see is not dependent as much on the quality of the microscope, as to the ability of the person looking through it. If you know how to use a microscope, you’ll do ok. This means knowing enough to overcome its limitations.

So, I had to already return the first of these I bought as the head was damaged and wouldn’t stay in place. So, this is my second and this one has a condenser ring assembly with a closed ring. As such, that makes the maximum height of any condenser it can use no more than 9mm. However, this phase contrast condenser has a height of 13mm. When I look at the pics showing of the microscope it does not have the same stage assembly as mine, specifically the condenser ring assembly. The one shown in the pics has an open ring assembly, thus allowing the taller phase contrast condenser to slide into place. However, as before, my ring assembly has a closed ring and thus blocks the taller phase contrast condenser from being able to be placed. Getting REALLY mad. Seems like a Mickey Mouse operation, but, then again, I don’t want to insult The Mouse as at least Disneyland runs with precision and professionalism. Where was this built? A spare bathroom in an abandoned building tilting to the left, with spare parts and the lights out?

It's better than other "name brand" ones we have looked at and have used. The optics is very good; the digital camera is cool (and can be used on other microscopes in the lab); and the service (thru online live chat and email) is excellent. I highly recommend it!

This trinocular compound microscope is super nice, the microscope has a high-end professional quality look and feel to it, the magnification and clarity are very impressive and the vertical camera and binocular mount is a nice added feature, another nice feature is 360° rotation, it makes a lot easier to share the microscope with lab partners, I also like that the focal wheel or knob has a tight feel to it, so it turns nicely and to free allowing me to get a slow and precise focuse of the specimen, the holgen bulb also has a rheostat to control the intensity of the light as well as a Kohler condenser with 2 iris diaphragms, so the light is super easy on the eyes, all in all I am super happy with the overall quality and performance of this trinocular compound microscope and although it is very pricey, I still feel it's definitely worth the investment.

Ojala vuelvan a venderlo lo acabo de comprar y mencionan que no estará disponible nuevamente, seria bueno cambien a iluminación LED
