Using a Microscope

Microscopes are like super-powered magnifying glasses that let you explore a hidden world of cells, bacteria, and other tiny structures. They work by using lenses to make objects appear much larger than they actually are.

Every microscope has essential parts you need to know. The objective lens does most of the magnifying work, whilst the ocular lens (eyepiece) is where you look through. The stage holds your specimen in place with clips, and the illuminator provides light from below to brighten your sample.

Getting a clear image takes practice, but it's dead simple once you know the steps. Start with the lowest magnification objective lens - this gives you a wider view and makes it easier to find your specimen. Always move the stage to its highest position first, then slowly bring it down using the coarse adjustment wheel.

Top Tip: Never start with high magnification! You'll spend ages trying to find your specimen and might miss it completely.

The fine adjustment wheel is your best friend for getting that perfectly sharp image. Once you've got a good view on low power, you can switch to higher magnification objective lenses to see incredible detail that would be impossible to spot otherwise.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Samantha KlichAndroid user

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
