AmScope SM-2TZZ-LED Professional Trinocular Stereo Zoom Microscope, WH10x and WH20x Eyepieces, 3.5X-180X Magnification, 0.7X-4.5X Zoom Objective, Upper and Lower LED Lighting, Pillar Stand, 110V-120V, Includes 0.5X and 2.0X Barlow Lenses

This scope works as expected, so I'd recommend it. However, in my experience I think the microscopy experience is enhanced with a scope camera. Don't skimp on a cheap camera for the scope though.

I bought this microscope in August and left it in the box until today, when I needed it for an experiment. Upon opening the box, I discovered that they sent me parts that did not fit together properly (nor did they send me the correct assembly booklet), making the microscope virtually useless. After trying to return the item, I was informed that the item was no longer eligible for return. I now have an extremely expensive paperweight.

Fair product for the price. Very convenient to have around the house. People told me it was like Zeiss, but cheaper. That's not true. Alignment on some things is a little off. The base isn't quite designed for the scope, so the object isn't in the middle. It doesn't go quite low or high enough for some uses. The tube on top is a little hard to attached dSLRs to -- AmScope adapters are poorly reviewed. Focusing makes a grinding noise. Etc. The edges of the field are also not all too sharp, for photos. You get what you pay for. But none of those really detract from the core use. It's easy to do fine work under, and it's interesting to see the world around us. Do price out combo vs. parts separately. I overpaid. Basic scope+parts was cheaper than buying as a kit. If I were buying again, I'd pass on the higher magnification Barlow lens. The images just aren't that sharp. It'd also be nicer with an aperture. Depth of field is a little limiting. The bottom lighting is essential. Many plants, fabrics, and similar are much nicer lit from the bottom. A few lamps around are also nice. Where the light comes from makes a big difference on what you can and cannot see.

This scope would have earned 5 stars if the included LED ringlight had glowed steadily instead of flashing on and off. This started after about 15 minutes of use, and made the ringlight useless. I ordered a new, separate ringlight rather than go to the trouble of returning the entire unit, and now I'm very happy with the system (it really does deserve 5 stars). The optics are very clear and sharp, with good flatness of field. The included extra eyepieces and supplementary objective lens give the unit a very high maximum magnification. Construction quality is excellent, with very smooth movement when focusing. I added an AmScope MU1003 camera to the trinocular port, and an AmScope GT100 X-Y stage for precisely moving the specimen. This is a basic stereoscope, nothing fancy, but it is solid optically and mechanically, and should serve very well for routine laboratory use.

Estoy muy satisfecho con este estereomicroscopio trinocular. Ofrece una buena nitidez de imagen en el plano del espécimen u objeto que estás observando, digo esto por la profundidad de campo que es muy limitada si el objeto ofrece relieves, resaltos o protuberancias. Has de enfocar más o menos para observar con nitidez el objeto que estás viendo. Si el objeto que estás observando es totalmente plano verás la imagen completamente nítida. Viene con lentes accesorias para ver los objetos o especímenes, ya sean muy diminutos o grandes (lentes 0.5x y 2x). Me he quedado sorprendido por la capacidad de magnificación que ofrece al ver una hormiga (Monomorium sp.) de sólo 2 milímetros. La he visto gigantesca. Le compré además una cámara que recomiendo (véanse mis opiniones/reseñas) para realizar fotos y vídeos, así como el adaptador con lente para acoplársela, y también un anillo de luz, aunque ya viene el estereomicroscopio con luces propias (incidente y transmitida). Pero me resultó útil y barato comprarle además este anillo de luz. Viéndose bastante bien. Para la identificación de insectos es ideal, ya que me dedico al control de plagas. Es un producto de calidad y tiene un precio bastante razonable. Sinceramente, habrá otro estereomicroscopio que valga el triple o más (Leica), pero este modelo (SM-2TZZ-LED de 3.5X-180X LED, así como la cámara de fotos y vídeos que además le he comprado (consultar mis reseñas) me ha dejado muy satisfecho. Lo único que he echado de menos (no venían con el paquete o caja) han sido unos protectores de goma o caucho para los “eyepieces”, ya que soy miope y uso gafas. Este estereomicroscopio viene con una funda antipolvo protectora. Le he comprado, además, un armario pequeño a medida para poder guardarlo y protegerlo del polvo. Le doy 5 estrellas.
