To magnify very small objects
A light microscope.
A simple microscope has only one lens and is used for magnifying small objects, while a compound microscope has multiple lenses and is used for magnifying very small objects with higher magnification and resolution.
simple or dissecting microscope -
A compound microscope consists of several lenses operating together, whereas a simple microscope is one lens, like a magnifying glass. A compound microscope gives higher magnification and also better resolution than a simple microscope.
The microscope used to discover bacteria was the light microscope, specifically the compound microscope. Anton van Leeuwenhoek, a Dutch scientist, first observed bacteria through a simple microscope he created in the late 1600s.

It was an extremely simple refraction microscope
The first microscope was called the "simple microscope" or "single lens microscope". It was developed in the late 16th century and consisted of a single convex lens used to magnify small objects.
The first microscope was a simple handheld magnifying glass, known as a "simple microscope." It had a single convex lens and was used to magnify small objects. The compound microscope, with two lenses for greater magnification, was developed later.

Yes, two lenses can make a simple microscope. More are usually used. A magnifying glass - one lens - is the simplest microscope.
