a compound microscope
An optical microscope uses light and one or more lenses to view cells. An optical microscope with two or more lenses is called a compound optical microscope.
A light microscope is called a compound microscope because it uses multiple lenses (a compound of lenses) to magnify the image of a specimen. This allows for higher magnification and resolution compared to a simple microscope.

Early lenses were called eyepieces.
They are called objective lenses.
The compound microscope is called compound because the modifier compound means "two or more." A compound microscope has two or more lenses lenses. This is to be distinguished from a simple microscope which has one lens. Such a microscope is structurally equivalent to a magnifying glass, though not necessarily a hand held lens.
The lenses attached to the nosepiece of a microscope are called objective lenses. They are used to magnify the specimen being viewed.
If a microscope has more than one lens, it is called a compound microscope.

The ocular lenses on a microscope are located at the top of the microscope's eyepiece tube. They are the lenses that you look through to view the magnified specimen on the microscope slide.
