What is a USB microscope?

It is basically a small digital microscope that can connected to your via a USB port. This allows you to view the image on your computer screen as opposed to looking through an eyepiece, this is achieved using software that accompanies your microscope.

What should you look for in a USB microscope?

Image quality – in terms of image, you shouldn’t be expecting the most high quality image, however you should have some reasonable expectations. For instance, the best ones typically have a 200x zoom, yet you’ll find the cheaper models don’t provide this and the 200x will seem more like 40x zoom. The image quality and optics is the most important criteria when selecting your microscope, as let’s face it, what’s the point in having one, if the image is bad?

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 with easily operated and clear controls.

Structure – all things small are that much easier to break or damage, that’s why it’s crucial to choose one that is well made with robust components. You will find that the very cheap models are incredibly delicate, while the ones that cost a little more will be a bit more enduring.

Price tag – the average one costs around $70, therefore if you pay more you should be expecting much more in terms of image quality and a more resilient structure.
