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.

Para el uso que yo lo quiero esta bien el microscopio. Me llego con 3 filtros de diferentes colores, no traía aceite de inmersión, tiene buena iluminación pero he notado que en ocasiones se baja un poco la intensidad de luz. Al encenderlo y durante el uso se escucha como un zumbidito.La relación calidad-precio me parece justa.Los fabricantes nunca me contestaron para mi factura.En general y para uso personal, me parece una buena compra ya que cumple con el objetivo. Lo recomiendo siempre y cuando no sea para uso laboral intenso.Las fotografías que agregué son tomadas con el objetivo de 40X, 10X y 4X.

Excellent microscope, found my first tardigrades with it :-) I wish I had the trinocular version but it as a lot more expensive.

I have used various light microscopes in academic and research settings for 45 years. Now that I am retired, I needed a low cost microscope to quantitate parasite eggs in goat feces at about 100x magnification. A $55 toy microscope might work well enough for this but I did not think that I would be satisfied with that and I might want to examine animalcules at higher magnification for entertainment. The Amscope B490B microscope appears to be a good compromise for the factors of cost, optical quality, and mechanical stability for a microscope.Specifically, the packaging was secure, the components were clean, and microscope assembly was easy. There were no missing parts. It had a plastic dust cover, an extra illuminator bulb, a spare fuse, and some immersion oil.All components (coarse focus, fine focus, stage transit, objective turret rotation, etc., worked smoothly. The microscope body appears to be well built with fairly close tolerances (except, perhaps, for the slightly loose oculars).The microscope illuminator was centered and the illumination was intense (and adjustable). The objectives are reasonably parfocal. Image quality is good, especially for the price (compared to a $10 research grade light microscope system.The manual was written with some strange phrases and terms but the content was adequate for me.The attached image was recorded with an hand held iPhone from the B490B LM eyepiece.

I have a BSc in Bio/Zoo but have never actually worked in that field but retain fondest memories of my microscope work (Cell Biology, Microbiology, etc) including some summer-break field stints as a Limnology student. Still, my passion for Bio/Zoo has never really diminished. As I move into retirement, I wanted to pick up a scope to resume my interest in aquatic invertibrates. I looked at some great used scopes but chose this one because of its price and I free shipping (Canada). I have only had the scope for a couple of days but have already put in about 5-6 hours of observing (mostly old slides I made back in '78, my own blood, and some pond water.) So far, I have REALLY ENJOYED this unit. Everything works as described. The objectives are achromatic but this is just fine for me, it was only really noticable when I was viewing some live Euglena at 1000X. The only concern I had is that the 100X objective is not marked "oil"...I have since confirmed with Amscope Customer Service that it is, in fact, an oil lens. I hope this is useful...I would buy this scope again.

I'm in a medical lab tech program and routinely work with $2000+ microscopes - this unit performs comparably well for a tenth of the price. As the top review notes, the field of view is a bit smaller than what you'd get with a clinical grade scope, but the resolution within the field of view is impressive. A few reviewers have said that the focus knobs are loose/imprecise but I've had no issues with them. The microscope seems very sturdy and well built.A few minor annoyances: there are no assembly instructions (although it's easy to put together) and it makes a buzzing noise when it's on. It comes with immersion oil, but no lens paper or cleaner for some reason. I've attached a photo of cheek cells and bacteria at 1000x, but it doesn't really do the scope justice because it was taken by holding my crappy phone camera up to the eyepieces. The image is much sharper in in real life.Overall an amazing microscope for the price.

I had bought my 6 year old daughter a toy microscope last Christmas. It was difficult to work with and not very satisfying. But, it did spark my daughter's interest. So, I determined that I would get her a "real" microscope for her 7th birthday. I looked around on Amazon.com until I found this one. The other reviews indicated that not only was it a good product, but a good product for a child (some of the reviewers were home schoolers). We set it up on my daughter's birthday, and it was clear as we unboxed it that this was a solid, quality, professional microscope. I had also bought a box of 100 prepared slides from Amazon so that there would be something to look at after we got the microscope set up. It really is a good microscope and I'm sure that it will follow my daughter through life as she grows up. Since then, I have also bought a slide making kit from Amazon so that my daughter can prepare her own slides. A side benefit is that my daughter's uncle is a scientist, so he can show her the joys of microscopy even more than I can! I was also going to get a stereo microscope to serve as a bridge between the "real" world and the microscopic one, but my brother beat me to it!. I don't have much experience with microscopes, but I did know as I was putting the microscope together out of the box that this was a solid, quality instrument.
