What is a magnifier and what magnification does it give?

A magnifier is the simplest of magnifying devices. It consists of a magnifying glass inserted into a frame. The magnifying glass is convex on both sides. A distinction is made between handheld and tripod magnifiers. The handheld loupe has a magnifying glass inserted into a frame with a handle. The handheld magnifier magnifies objects by 2-20 times. A tripod magnifier has two magnifying glasses inserted into a frame fixed on a stand – a tripod. A stage with a hole and a mirror is attached to the tripod. A tripod magnifier magnifies objects by 10-25 times.
