Do you want to purchase a microscope? Before you start researching what's being offered, you will find certain things you need to know if you want to avoid creating a mistake.
You realize that the microscope is basically an instrument in which one lens is put in front of another lens, to create objects look big. But that doesn't signify a microscope is all about magnification. All depends on what you need to utilize it for.
If your microscope has x30 magnification, it indicates an object seen with its 30 times larger than as seen with the naked eye.To see tiny bacteria, you would need x1000 magnification, but you can see an individual blood cell at x500. Magnification of around 400X is enough for most people. You can read more information about microscopes at https://www.microscopeinternational.com/product/olympus-cx23-binocular-microscope/.
These have just one eyepiece, which means you keep one eye closed. They provide you with a three-dimensional (3D) view of an object. The magnification is usually low, between x20 and x40.
An advantage of using them is that you could examine samples in their natural state, and need to do little or nothing to organize them.
They are great for taking a look at insects, coins, stamps, gems, plants and etc, so can be especially suited for education and for collectors and naturalists. But they're no use for taking a look at cells
