Whether you are a scientist or a hobbyist who wants to know more about the small things in our world, investing in a good USB digital microscope is a huge step forward to examine tiny structures in detail.
In this article, we show you what aspects you should consider before buying a digital microscope and how to choose a microscope that fits your requirements.
Finally, we show you a top list of our favorite USB microscopes. Now, please click a link below for quick navigation.
Finding the right microscope for your task
Choose your platform
Some digital microscopes work on several operating systems (Windows, OSX, Linux, iPhone, Android..). Some also come as a stand-alone device with the possibility of transferring data via USB or SD card to your computer.
So you should ask yourself: Which interfaces are required? (SD card, USB connection, internal storage, WiFi, HDMI…)
What magnification do you need?
Before you try to put tiny things under the lens of your device, you need to know if your object is even visible when using less powerful microscopes. Overall, you need enough magnification for your ask. Typically the magnification of digital microscopes ranges from 20x up to over 1000x.
In general, the higher magnification is, the more details you will see. But higher magnification also requires more prep works. This can include proper placement on the glass, adding immersion oil and cleaning the microscope from oil when you are done.
For example, with a 20-40x lens, you can already see single leaf cells.
Moreover, you’ll need a 400x lens to get a good look at a bacteria and over 1000x for professional high detailed microscopy.
How expensive is a digital USB microscope?
Prices for microscopes range from $20 up to over $2000. Thus you need to think about how much money you are willing to spend on your new magnifier.
Maybe, when you get a peek at the wonders of the world around us, you’ll be thankful you invested in a more advanced model.

Differences between digital and analog microscopes
Digital USB microscopes allow you to plug your microscope to your computer.
Thus, you don’t need to look through an eyepiece and you can see the image on your computer. This helps a lot when zooming in and out.
Moreover, a USB microscope makes it easy to save screenshots on your computer and quickly edit images.
Compared to traditional analog microscopes, USB microscopes are an advantage for every scientist and hobby user. But, if you need a tool to look into pipes and holes, you should check our article about borescopes and endoscopes.
back to menu ↑What can you do with a Microscope?
If you own a microscope, there’s no need to leave it in a cupboard gathering dust. There are plenty of creative ways to use your device, with all kinds of practical, artistic and educational benefits.
Let’s have a look at a few possibilities.
Discover the hidden life of ponds and lakes
If you live near a body of water, it’s a treasure trove of quirky creatures and wondrous sights. Just take a pipette or two of liquid from your local pond and place it on a slide, then apply the cover slip very carefully.
When you look at it in more detail, you’ll see a little world of critters such as protozoa.
Study the differences between leaves
Ponds aren’t the only area of the natural world that look magical under standard microscopes. Leaves, grasses, flowers and ferns are just as fascinating.
Look closely to see the stomata (holes used by plants to breathe), as well as how the epidermal cells create a barrier to protect the spongy cells underneath.
Find the tardigrades in a moss sample
Moss is another great source of microscopic sights. If you gather a small sample of moss or lichen and soak it for a few hours in pure water then dry it, you should find the resulting sample is teeming with “tardigrades.”
Also known as water bears, these amazing little creatures resemble tiny walruses or bears and can only be seen under a microscope.
Get a good look at the dust in your home
If you have the stomach for it, it’s also fascinating to magnify the dust in your home (we all have some hanging around).
When you do so, you can really uncover some secrets about modern life. For instance, you’ll see tiny flakes of cosmetics, plastic particles and glass, as well as fearsome dust mites that can give you a shock at first glance.
Analyze technical materials
A microscope lets you analyze the cross-section of technical materials. For example, you can find material defects like pores, cracks or structural defects.
A typical application for a microscope in technical analysis is also the weld seam analysis of weld seam cross sections. Under your microscope you can see if the weld penetration depth is sufficient and you can check if there are no cracks in the weld seam.
