The microscope is a slightly smaller than name brand microscopes, yet it does not fail to produce the same results as name brand microscopes. The microscope comes with a 5x, 10x, 40x, and 100x objectives. Again the OMAX come with 4 main objectives (5x,10x, 40x, and 100x) and 2 sets of ocular objectives (10x and 20x). UPGRADES - The ocular objectives are removable, so these can be swapped out for better ocular objectives, Also the main objectives (5x, 10x, 40x, and 100x) are removable, so these can be swapped out for better objectives. THE PACKAGE - The OMAX came with the microscope along with the 4 main objectives and 2 ocular objectives. The OMAX also came with a two ocular covers, so if one would like to store the microscope the ocular objectives can be removed and covers can be placed in the eye piece slots. All I had to do was plug it in and pop in the ocular objects to begin viewing things under the microscope. This is a great high quality microscope that produces the same results as name brand microscopes. Some people might be tempted to purchase a microscope for more money because of the rationale that more money equates to better quality but the OMAX delivers the same results as the Olympus and Nikon microscopes for a fraction of the price. If your looking to buy to buy a microscope to do college or professional work or use just looking to buy a hobby microscope look no further. With the OMAX i can view probably about 95 percent of the slide because the X axis does not have the same range as high end microscope, but this is not an issue for me. I was hesitant to buy this microscope because of the low price, but was pleasantly surprised when it came operated like and better than the microscopes on campus."
"And, as we will see below, most microscope kits don't offer any intermediate magnifications between 1000X and the maximum magnification they offer (2000X or 2500X), so that maximum magnification doesn't really give you any extra resolution over a 1000X microscope. Compound microscopes obtain their magnifications by combining the eyepiece magnification with the objective magnification. The objective magnifications usually are: 4X, 10X, 40X, and 100X. The 100X objective cannot be used as is, it requires a special immersion oil (see: en.wikipedia.org/wiki/Oil_immersion for explanation); so in inexpensive microscopes, this objective is usually missing, Regarding eyepieces, you usually get 10X or pairs of 10x+20X or 10X+25X. I still don't have an exact formula, as it depends on several factors including the wavelength of the illumination light, but a comment to this review pointed me to a rule of thumb that I also found mentioned in a Zeiss article on microscopy - that rule says that the maximum magnification that can be expected to be achieved with an objective would be 1000 times the numerical aperture value of the objective - see zeiss-campus.magnet.fsu.edu/articles/basics/resolution.html). The numerical apertures and maximum magnifications for the OMAX objectives are the following: 4X (0.10/100X), 10X (0.25/250X), 40X (0.65/650X), 100X (1.25/1250X). So, if we exclude the false magnifications, these are the magnifications that we can expect from each combination of objective and eyepiece (note that even this is optimistic, because we evaluated the maximum magnification, which we will probably not reach in practice): 10X: 40X (with 4X objective), 100X (with 10X), 400X (with 40X), 1000X (with 100X). A few more things you should know about this OMAX microscope: The objectives come pre-installed, but not everything is configured for optimal operation. There is a focusing rack stop screw that is supposed to help prevent the slides from being pushed into the larger magnification objectives (40X and 100X) - that screw will need to be adjusted as it does not come pre-set and on my sample it allowed the slides to be pushed into the high magnification objectives (40X and 100X - those objectives are spring loaded to prevent damage, but it is better to avoid it by also limiting the movement of the stage using this screw). A few accessories suggested: OMAX A Pair of Rubber Eyecups for Microscopes with 23.2mm Eyepieces. OMAX 60X Achromatic Objective Lens (spring) for Compound Microscopes. Some quick comments on these items: - The rubber cups are very nice and I wish they were included even if they had to bump the price of the package - they really make it more comfortable to use the eyepieces."
"Within one minute of opening the box, I used my Galaxy 5 phone camera and snapped this pic of the microbes on some old cheese."
"I am a veterinarian that purchased this microscope for use in my clinic (for examination of blood, tissue, urine, fecal samples, etc)."
"I put a drop of my blood on a slide and went looking around in it at 1000x seeing things I had no idea of. One thing, I wish it had come with a manual."

"This is a superbly built microscope!"
"Good quality for the price, I am having issues with my USB working - sometimes does, sometimes doesn't, and I've only had it 1 week."
"This is a really nice microscope!"
"I do like this microscope."
"This is a really marvelous piece of equipment for the price."
"I'm a beginner, and this was really easy to set up and get started with."
"I bought this for 8th grade budding scientist!"
The USB digital imaging system captures still microscope images and live video on computer without the hassle of setting up the digital camera. The digital microscope provides light from beneath the stage and are best for viewing biological specimen that allows light to pass through.

"This microscope works great for the purpose I bought it for, and I was pleasantly surprised at the quality of the scope and images for the low price I paid. For print quality images, I prefer to use the higher resolution cameras on the more expensive scopes at the university, but for online image archiving and class use, this scope does a great job."
"Don’t let the description mislead you."
"I got it in ,it works fantastic."
"Great resolution, easy way to use *ALL* the objectives and, really liked the capability to capture images in the PC."
"A high quality optical instrument delivered within days at a value price with a responsive and engaged merchant....I strongly recommend this product."
"Incredible value and quality for the price."

I found that for live, smooth video recording (and for focusing), I needed to use the lowest resolution for quick moving subjects. At first I thought that this and the 5-MP microscope were the same scope with a different camera but, after looking at the details, it appears that the controls and heft of this one is a notch above the less expensive (though I'm sure a good quality) 5 Megapixel CS-M83ES-C50U version."
"This thing is awesome!"
"Impressed with this microscope's optics!"
"If you are wanting a great microscope with a great camara you will love this one."
"The 14 MP camera is amazing and it allows for you to digitally zoom in which allows you to get a even closer view! The only very small detail that I can complain about is that the focus is just a bit off from the camera to the eye piece but that's not a big deal."
"Cons: It comes with camera software but you must purchase an additional TS-M1 micrometer slide to calibrate the scope camera so the software is ready to use. A plus to this is these are $10 slides and inexpensive only if your calibration needs are within tolerance of .01 mm (10 micrometers) but the microscope dealer should inform the consumer of the whole package requirements to get at least a slide measurable."
"I had a problem with the computer disc that came with it but customer support was excellent, I received the links to download the disc from internet within five minuets of contacting OMAX."
"Needed a work around with several attempts so that software would work with it."

"Picture 1 is a fruit fly taken with the 40x objective lens. Picture 2 is a fruit fly taken with the 4x objective lens. Picture 3 is cheek cells stained with an IKI indicator with the 40x objective lens. Picture 4 is an onion root tip with the 10x objective lens."
"I also purchased a gram stain and bacterial growth kit and I am having waaaaay too much fun."
"I bought this to check fecal samples for worm eggs in my animals, to assess wool fiber quality, and to identify bacteria and fungus in cultures."
"I give prepared slides, Greg's Microscope, The World in a Drop of Water, and AmScope The World of the Microscope A Practical Introduction with Projects and Activities along with it."
"Very high quality and solid metal frame."
"My biggest disappointment is the optics are not very clean but good enough for looking at bugs, and goo with my five year old grandson."
"Long story short, I guess I was stupid for thinking that a microscope would come with glass slides included."
