## Overview

The AmScope T490B is a professional-grade compound trinocular microscope offering an impressive 40X-2000X magnification range. Designed for veterinarians, breeders, and clinical labs, it features a simul-focal trinocular head with a 23mm photo port and included C-mount adapter for seamless imaging. Its 3D two-layer mechanical stage with low-position controls ensures precise specimen handling, while warm halogen lighting provides superior color rendering and reduced eye strain. Built with ergonomic 30° angled eyepieces and adjustable spacing, the T490B supports extended use with comfort and reliability, backed by a 5-year manufacturer warranty.

## Description

The T490 is our hardest-working, go-to microscope. The top choice for veterinarians, breeders, and clinics, this instrument has proven reliability and optical quality. It boasts features such as a compensation-free Siedentopf head, smooth stage translation, and a precision focus system with easy tension-adjustment and vertical-lock. The simul-focal trinocular head provides a dedicated photo port which can be used simultaneously with both eyepieces. The 490 series offers a wide range of optional accessories to expand the functionality. The magnification range can be expanded with a large selection of objective and ocular lenses. Specialized condensers are available for dark-field and phase-contrast applications, ideal for bloodwork, fluid-analysis, and pathology. To customize the microscope to your viewing comfort, the eyepiece spacing can be easily adjusted using a precision Siedentopf mechanism. A diopter is available on the both ocular tubes to compensate for asymmetry, and the ocular tubes are angled at 30° to comfortably accommodate a seated position without neck strain. The 23mm photo port is height-adjustable to match focus with the eyepieces, and can be replaced with an optional CX series C-mount port which have built-in reduction, and can directly interface with C-mount cameras. The 2-layer mechanical stage provides smooth and precise movement for examination of specimen slides. The stage's low-position controls are conveniently placed near the coaxial focus knobs for a streamlined workflow. Examining specimen slides is intuitive and precise for users at any skill level. Halogen sub-stage lighting provides bright illumination with excellent color rendering. The warm lighting is better suited for prolonged use, causing less eyestrain than LED and fluorescent lighting. The Abbe light condenser has a high 1.25 numerical aperture for oil-immersion, and an iris diaphragm to optimize contrast and depth-of-field. The condenser holder uses rack-and-pinion movement for precise height adjustment.

Review: Great microscope, great company! - As a retired high school biology teacher I am indulging in my lifelong passion for interacting with the living world by exploring local pond micro-organisms. Hence, my purchase of this scope. I had, admittedly, an inauspicious start. About 15 minutes into its first use, the illumination system failed. I tried everything - switching to the supplied replacement bulb, testing both bulbs for continuity, replacing the fuse, checking source voltage, etc. It was a serious disappointment! But, hey, stuff happens. The situation quickly improved. I can only say wonderful things about the tech support at AmScope. It was all done by email. My first email got a very quick and courteous response suggesting a few things to check which I did to no avail. Josiah from tech support then immediately sent out a replacement illumination base which installed easily and has functioned perfectly for a number of hours since. Kudos to AmScope support! Now, to the microscope itself. From college through 50 years of teaching I have used microscopes ranging from cheap to very high end. I am impressed with how close a microscope at this price point comes to matching performance of far more expensive instruments. The base, stage, turret, and eyepiece mount are solidly built and stable. There is no vibration in the image when changing focus or moving the slide. All lighting adjustments are easy to perform. The lamp itself has a dimmer control and the substage Abbe condenser moves smoothly. I still have to physically look for the diaphragm adjustment arm on occasion - something I should be able to do by feel, but that's a minor problem. The coarse and fine focus work smoothly with no slippage and no backlash when changing up and down focus. (There is also an adjustment for level of friction in the focusing mechanism.) The moving stage and its controls for x-y axis movement of the slide is a pleasure to use (particularly on swimming protists at higher magnifications!). Movement is smooth and precise on both axes and changing directions is immediate with no slipping at the control knobs. Most important - the optics. There are 4 objectives included (4x, 10x, 40x, and 100x) plus a pair of 10x and 20x eyepieces. I have not used the 100x oil immersion objective since it has limited utility for my purposes. I have made use, however, of the other three objectives with both sets of eyepieces. All combinations show even brightness across the field of view (if substage illumination is correctly set), no focus distortion (coma) at the edge of the field, and no color distortion. In short, excellent optics. Also notable: an object in focus and in the center of view at low magnification appears in the center of view when higher power objectives are moved into place and only minor focus adjustments are necessary at each change. I also cannot comment on the vertical viewing port since I have not attempted photography but look forward to trying it out in the near future. In sum, I'm thrilled that such a good instrument could be had at this low price. Spending more, even a lot more, would only produce diminishing returns.
Review: Great lab quality microscope - Purchased this for field study and home use. I love the stage, the generous size and coordinates make exploring your slides easy. With the trinocular port you can capture images while observing in real time, or show your work in real time on a external monitor which is why I purchased a real trinocular instead of a binocular with a camera port. I have used a cheap webcam, DSLR camera, cellphone camera and a point and shoot to take pictures and HD video successfully. I use this mainly for micromorphology and soil samples but have also observed tissue samples and cells with excellent clarity. The condenser and lamp are easily adjusted and as bright as you can stand, the body and construction are sturdy and of quailty material. The turret for the eye and camera pieces is a nice touch and works well and the objectives and eyepieces were dust free and come with good cases. Overall I couldn't be happier with my purchase so far after around three months.

### ⭐⭐⭐⭐ Fantastic microscope..BUT lighting could be better.
*by N***K on January 29, 2014*

I am a student who purchased this microscope to learn more on my own instead of relying on school labs that are typically rushed, feeling like a factory assembly line with massive students in queue. I like to observe things at length without time constraints - that is part of my learning personality. This microscope is a beast! A solid piece of equipment! It feels exactly like a lab microscope. It arrived packaged with a few things like a plastic cover to store it from dust, adapter for monocular, and color filters. Everything feels solid from the focusing knob, fine-focus knob, to the articulating stage. I love that you can articulate the stereo eyepiece and that it is not fixed like some microscopes. I have read that the optical lenses are made by the same company that makes lenses for Leica, Olympus, and other brand names in the microscope arena. The build of this microscope and lens feel superb! 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. But behold, if you Google 'microscope led hack,' you should find a few sites on how to LED your microscope. Amscope also sells an LED microscope light attachment for $30 bucks, which I think it can be used (or hacked) for this model. You may find the microscope light fantastic as it is. It does work fine, but I personally think it could be better, since LED is a more quality light and actually cheaper than halogen. It also seems that LED technology is now becoming the standard lighting in modern microscopes. Ever lived in a house/apartment with standard incandescent bulbs and you noticed how everything became vivid-like after changing to fluorescent bulbs (or even LED)? That's the similar effect you'll find with a microscope with LED. The star rating is 5 stars for the microscope, and 4 1/2 stars on the light. OH, for beginners, don't forget to calibrate (or adjust) your light/diaphragm on the microscope. I don't think this is quite important, as it was never taught in lab. It is like a 1 minute process that involves placing a paper under the light (one of the methods I came across), and adjusting other stuff like diaphragm to get a clearer, defined view. Doesn't hurt. Google 'adjusting microscope' or some type of variation like that.
