Best USB Microscope – A Comprehensive Guide

USB Microscopes are a great modern innovation which has made the use of microscopes far more convenient and accessible for both professional use and fun alike! They can be used by both the professional and the hobbyist and although they lack the magnification and precision of classical compound microscopes, they are still an interesting tool to have at your disposal.

USB microscopes allow specimen images to be saved at the click of a button so that they can be stored, viewed and even printed later on, fantastic for a kids school project or for comparing materials. There are many USB microscopes, that’s why it’s a wise idea to understand how they work in order to ensure you secure yourself with a good model that’s worth your money.

What is a USB microscope?

It’s a small digital microscope that can be connected to your computers, laptops or other compatible devices via a USB cable. This allows you to view the image on a screen as opposed to looking through an eyepiece, this is achieved using software that accompanies your microscope. This can be much more user-friendly and is also useful to display the blown up image onto a projector to be shared to a whole room, very handy for science class.

They can be used by an array of different people from homeschooling parents to professionals who compare samples in their field and even auctioneers; you can have great fun with the kids and carry out an engaging learning experience with them.  Stamp, coin, rock and other collectors also benefit greatly from the convenience and affordability of them.

Due to their basic design and materials, they are incredibly cheap for the manufacturer to produce and as a result can be bought for next to nothing. However this has resulted in a myriad of new companies popping up and producing very low-quality versions, so how do you choose the best USB microscope? And make sure you know what to avoid?

What should you look for in a USB microscope?

Image quality – In terms of image, don’t expect an image quality that you would find with decent compound microscopes. For instance, the best USB ones typically have a 200x zoom but this would typically depend on the amount you wish to spend, there are cheaper products which can have as little as 40x. Image quality would also depend on the size of the monitor that the resulting image is being presented.

Software – Nearly all digital microscopes come with software which allows you to install your new microscope, take photos and film your investigations. For this reason, it’s essential your software is easy to use and appealing.

Functionality – One of the key reasons they are so popular is that they are supposed to be easy to use. Therefore you want to opt for one that is easy for you to set up; only being as complicated as you need them to be. This will come into how easy it can be adjusted and how portable they are.

Structure – All things small in design are that much easier to break, damage or even lose, that’s why it’s crucial to choose one that has robust components that are secure to reduce exposure to liquids and particulates. You will find that the very cheap models are incredibly delicate, while the ones that cost a little more are more likely to recover from drops and knocks.

Price tag – The average USB microscope costs around $70, therefore if you pay more you should be expecting much more in terms of image quality, features, and user-friendliness; if not, you are wasting your money.

It’s very enjoyable to find samples at home and see what you can find under a microscope, taking note of the tiny structures which make up the physical world. Some would like to take a closer inspection of themselves as well as the world around them just out of interest or to do a quick checkup.

This USB microscope makes it easy for you to do that as it comes with multiple attachments, allowing you to check inside your ear, check your skin and teeth. Of course, it’s not wise to be doing any home diagnosis but it’s still interesting nonetheless and if you did, for example, feel something odd in your outer ear, there’s no harm in giving a quick check just to confirm if there was any blockage or problem before checking in with the doctor.

The microscope has a magnification range between 10x and 200x, similar to most models, and a 1-megapixel pixel camera with 1280 x 720 – suitable for most monitors. It’s also connectible to Windows and Mac operating systems and even Android devices; with an app downloadable from the Google play store. The camera head is waterproof too so inspection of submerged samples is possible.
