Product Description

The AmScope M158C monocular compound microscope has interchangeable 10x widefield and 25x widefield eyepieces, a forward-facing nosepiece with three DIN achromatic objectives, rheostat-controlled LED illumination, coaxial coarse and fine focus, a 0.65 NA single-lens condenser, and a plain stage. The forward-facing revolving nosepiece has 4x, 10x, and 40x DIN achromatic full-glass objectives that provide high-resolution color-corrected images. The monocular viewing head has one 10x widefield eyepiece on a fixed 45-degree vertical inclination to reduce eye and neck strain and 360-degree rotation capability to provide a more comprehensive view and enable sharing. A compound microscope is used for inspection and dissection of specimens when two-dimensional images are desired.

The microscope has lower (diascopic) Brightfield illumination that transmits light up through the specimen for enhanced visibility of translucent and transparent objects. Brightfield (BF) illumination allows the specimen to absorb light, resulting in a dark image on a light background. LED illumination provides bright, cool light for working with temperature-sensitive or live specimens. Rheostat control capability allows the viewer to control light intensity. The 0.65 NA single-lens condenser and disc diaphragm control the amount of light illuminating the specimen. The plain stage is 3-1/2 x 3-1/2 inches and has an opening for light transmission and stage clips to secure the slide or specimen in place while viewing. A stage stop prevents the stage or specimen from coming into contact with the objectives. Coaxial coarse and fine focus knobs are nested to speed focusing for left-and right-handed viewers. All mechanical components are constructed of metal for precision and durability, and the solid-metal frame has a stain-resistant enamel finish. The microscope is powered by a 110VAC adapter (included) or by three AA batteries (sold separately) for field use.

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.

United Scope manufactures microscopy equipment and accessories under the brand name AmScope. The company, founded in 1996, is headquartered in Irvine, CA.

The microscope itself is pretty solid. The included 25x eyepiece, which is needed to reach 1000x, doesn't fit the scope securely as far as I can tell. There may be some way to do it, but the instructions won't help you there. If you're like me and try to do it anyway, be prepared to grab a magnet to fish up the tiny (TINY) screw that holds the 10x eyepiece in place. For the 4x and 10x objective lenses, you can use cheapo slides, stacked 2 high. This is good enough to check out plasma cells flying around, hair structure, fly wings and other commonly available things that strike your nerdy fancy. As a casual hobby microscope, this thing is totally worth it.

HOWEVER: The 40x objective can't focus that high above the stage. You'll need thin (.8mm or less) or depression slides, which are slightly more expensive, and slips in order to really get in tight for microbes, amoebae, and carbon fiber robot building (you should probably have a pro 'scope for that, anyway). It shouldn't deter you from buying, but be sure to add the right slides/supplies to your order.

Also, if the portability is a seller for you, I'll add that there is clearly a battery compartment in this model. However, and I'll concede that I may just be stupid, I can't figure out how to get that bad boy open.

EDIT: 6 months later, I found myself in a situation that required the use of the battery, and I decided to go for broke. Pliers remove the cap easily, and the fastener beneath the cap is sturdy enough that it won't cause damage. Disregard my portability complaint.

I purchased this product as a Christmas gift for my child. We did a lot of comparison shopping and had a lot of fun selecting this one because it was mid-range in price and appeaered to be a good quality item.

When the scope arrived, we opened it right away. That is when our dissapointment began. The scope is not "all metal." The body is indeed metal, but many of the other parts, including the casing around the light, are not.

Nevertheless, the unit appeared sturdy enough, so we decided to give it a whirl with some slides I had purchased as well. We got the light to work, but every time we even slightly moved the unit to insert a slide or adjust the view, the light flickered on and off.

We promptly contacted the seller, who seemed happy enough to take the unit back. He sent me a mailing label and apologized for my inconvenience. That is when the fun started. This seller only refunded part of the cost of the unit. When I emailed him to ask why, he informed me that he had been able to get the light to work for five hours continuously by plugging it in at his shop. Because of this, he charged me a $20 shipping charge. Of course, I also got the light to work when the unit was just sitting there, but this is not a lamp, it is a precision instrument.

We then proceeded to exchange emails abour this all day. I am not sure how much this guy makes an hour. Given his poor customer service ethic and obvious overpaying for postage, I am sure it is not alot. But I am also sure it cost him more than $20 of his time to exchange emails with me and insult me by insinuating that I was lying about the defective condition of the microscope.

Bottom line, this is not a good product or a good seller. I highly recommend moving on.

Great microscope for the kitchen biologist. The optics are decent (not amazing) and it a fairly solid unit. The adjustable brightness of the light is very helpful and the micro-adjusting knob is essential on a microscope of this power. Overall, a good buy if you want something for non-professional use.

Ordered this for my son that is homeschooled. We needed the microscope for his Biology class. He loves it. Having this microscope available has made Biology much more exciting to study.

I enjoy this microscope. It has everything that I would need and then some. It's an excellent price for something of this quality in my opinion. Everything works just as expected... but I wouldn't necessarily use a plastic locking mechanism in my fine lens TBH.

I got this microscope to check for parasites. Perfect! Works great and good price. Light is bright. Ac plug or 3 aaa, comes with both and cover. Will need to buy slides. I use this when checking my koi for parasites. Easy to grab and check a sample right at the pond. When serious $$$ is involved, the right tools is needed. A must have for serious koi keepers.

Very happy with this purchase. I received it within a reasonable time. The price is great for what I got. I am a home school mom and will be able to take advantage of my daughters natural curiosity to explore. The instructions could be a lot better. It was confusing to change the lens out. However, I was able to find information on line that helped me. Overall... Great product for a great price. Best of all, she will be able to use this thru High School. I would recommend purchasing some prepared slides to get started. Not the Lab quality scopes that I was used to working with in the Lab, But this is a great quality started scope that gets the job done.

Great customer service and product. I received the microscope on time, however the ocular piece was defective as it would not remain intact due to threading misallignment by manufacturer. Although Amazon mistakenly offered to give me a refund inc s&h without contacting the seller, assuming Amscope would not be able to replace it, Amscope had contacted me immediately regarding the issue, once my disappointed feedback was posted. Within 2 days, I received a new microscope at excellent condition and free s&h. No stress involved! I just need to send the previous one back, also s&h prepaid by the Amscope. Gladly, I removed the negative remarks.

Re: microscope, all metal body. Knobs are not metal, but overall, very sturdy and will be great for a small classroom of students. The movements are very smooth...great buy!
