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 since 1996, headquartering in Irvine, CA.

As a home-schooling mom of 6 I can't say enough about this scope. We have struggled with several under $100 microscopes and I wish we would have started with this one. It is simple enough for our 4 year old to use and advanced enough for our son in college. The mechanical stage is a definite plus making it easy to find all sorts of creatures and to give coordinates for science assignments. This is better than the scope I used in college and we have had a great time with it. I would recommend purchasing slides, a good how to guide etc because you will quickly become addicted. Nothing beats the right tool to get the job done and all of a sudden, science is the favorite class. We have studied parameciums to stem cuttings. The only thing I can think of that makes this less than perfect is that I need a case. The desciption neglects to tell you what is included - 2 light filters, a lighting iris diaphragm to control light levels, dust cover - in short it was more than I expected. Crystal clear images and with some maneuvering we can get a 3d image.
The price can't be beat (especially with free shipping)- I HIGHLY recommend this scope and can't imagine a kid not mesmerized examining his own blood,cheek cells, dust mites, algae, pond creatures, pollen, bees' legs, flies' wings etc, etc

Item arrived on time, well packaged and in perfect condition.
This microscope is well made and of metal construction. I have wanted a microscope for many years but the models I found in local hobby shops were either way too expensive or cheaply constructed of plastic. Thanks to Amazon, I was able to find and select this quality product. Upon receipt, I performed the simple assembly within 10 minutes and was viewing paramecium, amoeba, planaria and other creatures in a drop of water from my backyard pond in no time at all. After about a month of ownership, I purchased a Celestron digital USB imager for less than 50 bucks and I can now view and photograph excellent images as well as create videos of anything seen through this microscope using my PC. The microscope comes with both 10X and 20X eyepieces as well as color filters (which I would love to know how to use if anyone can advise me how to mount them) and a fantastic X / Y micrometer type clamping device which allows one to find an object, note its coordinates, move on and return to it easily rather than moving a slide with your fingers and possibly creating a mess. If you are looking for a well made hobby grade microscope for a very reasonable price, this is it. Do not be put off by the fact that this is not a well known name brand.

I'm a research scientist and know high quality microscopes in my lab and even for the classroom are pricey. This is a very economical microscope that is of excellent quality. My kids and I have had a blast looking at pond water (algae, paramecium, round worms), small ticks (Here we used it to see if the entire tick was removed...it was), molds (hyphae and spores), budding yeast, etc. My ten year-old is picking up a lot of info and my 4 year-old is also enjoying it...who knows how much he is picking up and who cares, he's engaged. I am making the slides, finding the items, and focusing, all that will come with time for the kids.

I did not find it difficult to assemble, but I have some experience there. It seemed pretty intuitive to me. It came in about 4 parts that were preassembled (body, stage, eye piece unit, slide holder). The light is very bright/effective, even at 100x and it comes with one replacement bulb. There is a lever to control the light passing up through the lenses. Not sure why one would want to use the color filters...these remain in the styrofoam packaging. All four objectives are excellent and you can use either the 10x or 20x eyepieces, which are also clear.

I got tired of waiting for the university sales where they sell their old microscopes. Getting a new 'scope is even better!

You will need microscope slides and cover slips, but those are also easy to find on Amazon. It comes with immersion oil for the 100x objective. It does not come with lens paper or cleaning solution to remove the oil off the lens or for general maintenance of the lenses.

We home school and had tried another microscope that was around 50-60 bucks cheaper. We got it and returned it, as there were several issues with the quality. We decided to try this one instead.

The construction is much better and feels solid. This scope is like the ones I worked with in undergrad - much more satisfied.

The only problem I've encountered is that the mechanical stage attachment isn't stable. I've triple checked and I have it attached correctly, but whenever turning the knobs to move the slide, there is a "wobble" in it that causes the view to be distorted and you have to refocus. This also causes the "latch" that catches the slide and fixes it into place to ride a little high and have trouble securing the slide into place consistently. I have "jury rigged" it by sliding a piece of folded paper under it to keep it more stable.

Overall pleased. Just curious as to why the mechanical stage attachment is a little off.
