AmScope T490B 40X-2000X Professional Trinocular Lab Education Biological Compound Microscope with 3D Two-Layer Mechanical Stage
From Manufacture:
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.

About Microscopes
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.

Tolles Preis Leistungsverhältnis, bei Objektiven sollte man natürlich keine Wunder erwarten.Artefakte im Bildhintergrund bei höheren Auflösungen, die mit der Beleuchtung etwas kompensiert werden können.Bei planen Motiven wie Planktonproben ist bis zur 2000 fachen Auflösung eine ausreichende Qualität ohne Öl für digitale Aufnahmen möglich.Hinweis zur digitalen Fotografie: der obere Trinokularkanal ist optisch leider nur für APS-C Sensoren ausgelegt und mit modernen spiegellosen Digitalkameras wie der Sony A7 R nicht zu gebrauchen ohne sich eine eigene Balg Konstruktion in Kombination mit Reduzierlinsen zu bauen.Eine Investition in diverse Adapter oder Reduzierlinsen lohne sich nicht - es reicht ein T2 Adapter auf die Okulargrösse am rechten Auge in dem Fall auf Sony E-Mount. Die Kamera wird vorne statt dem Okular eingeschoben und der 60 Megapixel Sensor mit ca 2/3 abgedeckt. Für Laborarbeit, Biologie und Ökologie eine kostengünstige aus meiner Sicht ausreichende Lösung !

Prior to ordering saw same scopes on Ebay for considerably less money, but were "open box". Consciously decided to pay the extra to purchase new from Amazon. What arrived had rust/corrosion on two different parts. There were remnants of hastily cleaned contaminants and small metallic scrap. Scope head had a gouge/scrape from previous use of set screw. Also missing the immersion oil. Lenses came in open resealable baggies. Bare filters jammed together into Styrofoam. There was some kind of perpetually tacky substance in a well defined pattern across (and probably into) the bulb heat vents. Sent email to Amscope and waited. A month later still no response and return window has expired. Not what I expected when I thought I was purchasing from a reputable source.

Ho acquistato il microscopio dopo una breve ricerca online, sembrava un buon compromesso. Lo è sicuramente. La meccanica è precisa, messa a fuoco e spostamenti del tavolo portaoggetti sono morbide e fluide. L'ottica piu' che buona per il costo dello strumento, quasi irrisorio.Il microscopio arriva in una scatola di polistirolo, forse l'unica pecca è la mancanza di una cassa con alloggio per i vari accessori (2 paia di oculari, prolunga per connessione a PC, fusibili, filtri, olio, lampadina di ricambio). Ha comunque un copristrumento in plastica che è efficace per tenere lontana la polvere.Dopo un paio di settimane di prove sono pienamente soddisfatto del funzionamento. E' vero che la lampada potrebbe essere piu' luminosa, ma ho lavorato con facilità a 2000x (obiettivo ad immersione) senza problemi.Non posso dire nulla dell'attacco PC perché non ho avuto modo di provarlo, per ora ho fatto qualche foto in proiezione oculare con un cellulare, come si vede dagli attachments la risoluzione è ottima. La prima foto è fatta a 800x, la seconda a 2000x in immersione.Assolutamente consigliabile per chi vuole divertirsi con la microbiologia.

Great scope! I also bought the Omax 9mp camera to use with it (through my Mac laptop and supplied Troup Lite app) and I'm getting some terrific photos. It's a waste of money buying a higher res camera for this work. Originally I was going to buy a special photo eyepiece for my Canon SLR, but I'm glad I went the way I did. Anyway...I'm going to put an LED lamp in place of the halogen (which gets hot, and will dry your wet samples). I've been using two gooseneck LED lights to include top lighting (like with a dissecting microscope)...getting really nice photos with three-dimensionality this way. Great scope for the money, and works as well as my old Olympus (which cost 6k at the time). I particularly enjoy the the Siedentoph head, much easier to get real binocular image with this than with the Omax scope I had to return (because of this issue). It's nice that quality scopes are so affordable these days. p.s....I'm going to get a 60x objective to use in place of the supplied 100x oil immersion objective. Sharing my photo of Black Oak pollen, apx diameter is 0.04mm (used sub-stage halogen and two top LED sources (one on each side) can vary illum output of each to enhance 3D effect). My three-way cheapo gooseneck LED lights are better than the single brightness unit I never use now. Hope this helps.

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.

Very robust construction. Great quality and very smooth focusing and panning. I've only used the 10x eyepieces with the 4x, 10x and 40x objectives. Nothing more that that yet, but so far I've enjoyed the views. I've also been able to attach my Panasonic Lumix G2 camera to the trinocular port using the included C-Mount adaptor. This required purchasing a cheap C Mount Lens to Micro 4/3 Adaptor.

I purchased this scope to replace a budget microscope from AMSCOPE, and I can honestly say I'm well impressed. The optics are really clear and build quality of the microscope is hard to beat, compared with my previous models from other companies who I won't mention. I think as a user of microscopes this is finally the last one I'll buy. The camera mount is great, I would advise getting an AMSCOPE camera just incase you run into comparability issues. This microscope fits all my wants by ticking every box. Love it thanks AMSCOPE.

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.
