Featuring a unique simul-focal optical system, it allows simultaneous sharp viewing through eyepieces and an adjustable trinocular port for imaging or third-party observation. Equipped with a heavy-duty 3D two-layer mechanical stage, coaxial coarse and fine focusing, and a variable halogen illumination system with Abbe condenser, this microscope delivers vibrant, distortion-free images ideal for clinical, educational, and research applications. Its robust metal build and versatile camera compatibility make it a top choice for professionals seeking precision and reliability. ## Description The T490B 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. 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. In addition, the T490B's industry standard 23mm photo port can be converted into a C-Mount port, 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.Features : - Eight magnifications: 40x-80x-100x-200x-400x-800x-1000x-2000x - Coaxial coarse & fine focusing with CA knob tension control - Fully coated optical system with high resolution - Abbe condenser with iris diaphragm & filters - Rack and pinion adjustment for condenser - Full optical glass elements - Review: 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: Can even see red blood cells, nice and sharp without a dark field condenser if you close the diagram a bit. I'm very satisfied with this purchase. ## Features - Three unique features: 1) Simultaneously views sharp clear images through the trinocular port and eyepieces; 2) Has both 23mm photo port and C-mount; 3) The Length of the trinocular port is adjustable - Professional widefield optical system offers eight magnification settings 40X-80X-100X-200X-400X-800X-1000X-2000X - Heavy-duty graduated 3D two-layer mechanical stage with coaxial coarse & fine focusing, rack & pinion adjusting Abbe condenser and iris diaphragm - High quality intensity-variable halogen illumination system provides full spectrum light, giving the most colorful microscopy images - Trinocular port uses the third port for camera capabilities, or a third party to view as well, giving you the remaining two ports to view your specimen ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004QEFO1Q | | Brand | AmScope | | Color | Black/White | | Compatible Devices | Camera | | Customer Reviews | 4.5 4.5 out of 5 stars (196) | | Enclosure Material | Metal | | Item Dimensions L x W x H | 50.8L x 43.2W x 26.7H centimeters | | Light Source Type | Halogen | | Magnification Maximum | 2000 x | | Manufacturer | United Scope LLC | | Manufacturer Part Number | T490B | | Model Number | T490B | | Objective Lens Description | 40X-2000X | | Power Source | Battery Powered | | Real Angle Of View | 30 Degrees | | UPC | 013964470000 | | Unit Count | 1 Count | | Voltage | 220 Volts | ## Product Details - **Colour:** Black/White - **Light source type:** Halogen - **Material:** Metal - **Product dimensions:** 50.8L x 43.2W x 26.7H centimeters - **Real angle view:** 30 Degrees ## Images ![40X-2000X Full-Size 17 Lbs Professional Trinocular Lab Biological Compound Microscope with 3D Two-Layer Mechanical Stage - Image 1](https://m.media-amazon.com/images/I/61hsZ81p48L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by J***C on 12 September 2017* 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.

I'm very satisfied with this purchase. ### ⭐⭐⭐⭐⭐ Review *by A***R on 11 June 2019* 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. ## Frequently Bought Together - AmScope T490B Compound Trinocular Microscope, 40X-2000X Magnification, Halogen Light, Abbe Condenser, 2-Layer Mechanical Stage, High-Resolution Optics, Awarded No. 6 Among The Top 10 Microscopes 2016 - AmScope BS-50P-100S-22 Pre-Cleaned Blank Ground Edge Glass Microscope Slides and 100pc Pre-Cleaned Square Glass Cover Slips Coverslips - AmScope Microscope Slide Preparation Kit Including Slides, Stains --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.it/products/268127921-40x-2000x-full-size-17-lbs-professional-trinocular-lab-biological](https://www.desertcart.it/products/268127921-40x-2000x-full-size-17-lbs-professional-trinocular-lab-biological) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-09*
