Today's microscopes use convex lenses.
The simple microscope, defined as having one lens, was enhanced by Leeuwenhoek. Many of the compound (multiple lensed) microscopes were blurry, but Leeuwenhoek ground his own lenses.
I think that in most school microscopes, it is 10x
It is an optical instrument that gathers light from the object being observed and focus the light rays to produce a real image. They are also called objectives. In microscopes, lenses are found at the bottom near the sample. They are mainly used at telescopes, microscopes and cameras.

A compound microscope has2 convex lens.
Microscopes have 2 convex lens and telescopes too while microscopes are used to look at cells and microscopic organisms.
There are many good companies that one can chose to purchase quality used microscopes. This includes companies such as Metallography and Gradient Lens.
Light microscopes are called compound because a light microscope has more than one lense.
Today's microscopes use convex lenses.
You can use a low power microscope for looking at large insects. Most low power microscopes are called "Stereo" or "Dissecting" microscopes and have two eyepieces and a separate objective lens for each eyepiece lens.
