AmScope T490B 40X-2000X Professional Trinocular Lab Education Biological Compound Microscope with 3D Two-Layer Mechanical Stage
AmScopeT490B features a unique simul-focal optical system with an adjustable trinocular port to enable well-focused clear images on your computer or video screen while simultaneously obtaining sharp, focused images through the eyepieces. In addition, the T490B's industry standard 23mm photo port can be converted into a C-Mount port by attaching the included C-mount adapter, allowing you to attach most microscope digital cameras and video systems on the market. The T490B includes a 30-degree inclined 360-degree swiveling trinocular Siedentopf head, a 3-D mechanical stage, and an intensity-variable halogen illumination system. This versatile microscope is also capable of being upgraded with various accessories and attachments listed in the optional section for additional functions. It is a perfect laboratory instrument for clinics, Vets, Doctors, and professional students. It arrives brand new in a factory sealed box.
Simul-focal Optical System
Most trinocular microscopes allow you to view either through the trinocular port or the eyepieces only, forcing you to switch between the two. Since these trinocular ports are not simul-focal with the rest of the microscope optical system, you have to re-focus the microscope after each switch. The T490B, however, erases this step by providing simul-focal viewing. Especially handy for teaching demonstrations, clinical examinations and laboratory applications, the simul-focal feature allows your students or colleagues to view clear images simultaneously while you work through the eyepieces.

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. AmScope has been manufacturing microscopy equipment and accessories since 1996, headquartering in Irvine, CA.

I also bought the Phase Contrast Kit (Model PCT) directly from Amscope for $684. When I was purchasing it, I thought it was a bit strange that Amscope priced the contrast kit so high since the microscopes it was designed to be used with cost only a fraction. I thought maybe the quality of the contrast kit might be high. Unfortunately, that wasn't the case. It was not really useable so I ended up returning it.
The reason why I mention the Phase Contrast kit is this. For anyone considering buying anything from Amscope, buy from Amazon if you can. Returning anything to Amazon is exceptionally easy. That's not the case if you buy directly from Amscope. I had to call 3 times to get an RMA number, then call 3 times to get a refund processed. They eventually refunded the full price less shipping cost but it took too much effort to make that happen. Their technical support is non-existent.
In terms of bang for the buck, this may be the best techie man toy ever.
Impressive presentation. It's huge, at 14-1/2 inches tall without a camera and almost 20 inches tall with a compact digital camera on the trinocular port. It would be a little taller with an SLR/DSLR camera.
Well constructed with a really solid feel to the whole thing. Knobs that move, such as the focusing knobs, the condenser positioning knob, and the stage positioning knobs, all move smoothly.
The optics are quite good. Achromatic (and not planar), obviously, at this price point. But certainly good enough for students and hobbyists like me.
This is no toy in the cheap sense of the word. This is a serious instrument.
Overall, a great value at the $380 I paid the T490B-DK kit. (Which is this T490B microscope bundled with its optional DK-DRY100 darkfield condenser). I recommend you save yourself $90 by buying the T490B without the darkfield condenser. You can add the condenser at any time.
Ideal for homeschooling.
As an 8-10 year old child circa 1950, I was given a cheap chemistry set and a toy microscope. I was never able to do anything with the chemistry set and the microscope was a useless piece of junk. Great idea. Encourage your kids to develop an interest in science by giving them scientific toys that do nothing but frustrate them.
If you're lucky enough to have a child who's interested in science, the smartest thing you can do for them would be to buy them this microscope and a few (2-4) boxes of prepared slides. The benefit is not just in the `discovery' value in getting really good views of really small things.Read more ›
The ability to attach a video camera/camera via the monocular port is an awesome feature. Canon cameras can attach without the current adapter if you purchase a Canon specific adapter by Amscope, which cost around $90.
My major dislike is the lighting. It works ok, but I personally find it not bright enough. I also found that the higher resolution I want to go, the light becomes duller, though still functional. The lighting is classic halogen, not LED, but I knew that when purchasing. Only a month afterwards did I have an opportunity to use an LED microscope. Boy, that lighting will spoil you. The LED lighting is super bright, producing a pleasant viewing experience (makes for better microscope pictures too). The super power efficient LED lasts for a long time with no heat build-up like a halogen.Read more ›
I love this microscope so much I can barely tear myself away. This is no toy, but a high quality microscope priced within reach for anyone. And you may be seriously surprised at the quality of the photos you can get with your phone.
